For the driver of the Peugeot 408, it is no secret that the indicator on the dashboard "Check-Engene" is a Peugeot malfunction signal. In a normal state, this icon should light up when the ignition is turned on, at this moment all Peugeot 408 systems are checked, in a working car the indicator goes out after a few seconds.

If something is wrong with the Peugeot 408, then "Check-Engene" does not go out, or it lights up again after a while. It can also blink, which clearly indicates a serious malfunction. This indicator will not tell the Peugeot owner what exactly the problem is, it draws attention to the fact that diagnostics of the Peugeot 408 engine is required.

Since all foreign cars, not excluding the Peugeot 408, are tightly tied to electronics, a huge number of sensors monitor the operation of the car. Therefore, diagnostics of the Peugeot 408 engine is, by and large, checking the most important unit of the car, with the exception of the suspension, which is checked mechanically.

There is a large number of specialized equipment for diagnosing the Peugeot 408 engine. There are compact and fairly versatile scanners that not only professionals can afford. But there are times when ordinary portable scanners do not detect malfunctions in the Peugeot 408 engine, then diagnostics must be carried out exclusively with licensed software and a scanner from Peugeot.

Peugeot Diagnostic Scanner shows:

• Throttle valve opening percentage;
• Engine speed in rpm;
• Peugeot engine temperature 408;
• Voltage in the Peugeot 408 on-board network;
• The temperature of the air sucked into the engine;
• Ignition timing for Peugeot 408;
• Fuel injection time by the injector. Displayed in milliseconds;
• Peugeot 408 air flow sensor readings;
• Peugeot 408 oxygen sensor readings;

Before diagnosing the Peugeot 408 engine, you should listen to it, in normal condition it works quietly, monotonously, confidently keeps the speed. When you press the gas pedal, it steadily, without jerking, picks up speed, without extraneous sounds. The exhaust is almost invisible. Also, in a normal Peugeot 408 engine, there can be no increased consumption of fuel and other liquids.

1. To diagnose the Peugeot 408 engine, first of all, the engine compartment is inspected visually. A serviceable engine should not have any leaks of technical fluids, be it oil, coolant, brake fluid. In general, it is important to periodically clean the Peugeot 408 engine from dust, sand, dirt, this is necessary not only for aesthetics, but also for normal heat dissipation!

2. Checking the oil level and condition of the Peugeot 408 engine, the second step of testing. To do this, you need to pull out the dipstick, and also look at the oil by unscrewing the filler cap. If the oil is black, and even worse black and thick, then this indicates that the oil has changed for a long time.

If there is a white emulsion on the filler cap or you can see how the oil foams, then this may indicate that water or coolant has entered the oil.

3. Checking spark plugs Peugeot 408. Remove all plugs from the engine; they can be checked one at a time. They must be dry. If the candles are covered with an insignificant layer of yellowish or light brown carbon deposits, then you should not worry, such carbon deposits are quite normal and permissible, and do not affect the work.

If there are traces of liquid oil on the Peugeot 408 spark plugs, then the piston rings or valve stem seals are likely to be replaced. Black carbon deposits indicate an over-enriched fuel mixture. The reason is improper operation of the Peugeot fuel system, or a too clogged air filter. The main symptom will be increased fuel consumption.

Red plaque on Peugeot 408 candles is formed due to low-quality gasoline, which contains a large amount of metal particles (for example, manganese, which increases the octane number of the fuel). Such a plaque conducts current well, which means that with a significant layer of this plaque, the current will flow through it without forming a spark.

4. The Peugeot 408 ignition coil does not often fail, most often this happens due to old age, insulation is damaged and a short circuit occurs. It is better to change the coils in accordance with the mileage according to the regulations. But it happens that bad candles or broken high-voltage wires cause damage. To check the Peugeot coil, it must be removed.

After removal, you need to make sure that the insulation is intact, there should be no black spots or cracks. Next, a multimeter should go into the course, if the coil is burnt out, then the device will show the maximum possible value. You should not check the Peugeot 408 coil using the old-fashioned method for the presence of a spark between the spark plugs and the metal part of the car. This method takes place in old cars, while on the Peugeot 408, due to such manipulations, not only the coil can burn out, but also the entire electrics of the car.

5. Is it possible to diagnose engine malfunction by smoke from the exhaust pipe of the Peugeot 408? Exhaust can tell a lot about the condition of an engine. In the warm season, no thick or bluish smoke should be visible from a serviceable car.

If white smoke is visible, then this may indicate a burned-out gasket or leakage in the Peugeot 408 cooling system. If the smoke is black, then at best it is a problem due to an over-enriched fuel mixture. At worst, problems with the piston group.

If the smoke has a bluish tint, it means that the Peugeot 408 engine uses oil. In the best case, it will require replacement of the valve stem seals, in the worst case, the repair of the piston group. All this fumes clogs up and shortens the life of the Peugeot 408 catalyst, which cannot cope with cleaning such impurities.

6. Diagnostics of the Peugeot 408 engine by sound. Sound is a gap, this is what the theory of mechanics says. There are gaps in almost all moving joints. This small gap contains a film of oil that prevents parts from touching. But over time, the gap widens, the oily film can no longer be evenly distributed, friction of the parts of the Peugeot 408 engine occurs, as a result of which very intense wear begins.

Each node in the Peugeot 408 engine has a specific sound:

• A loud, frequent sound heard at all engine speeds indicates the need to adjust the valves;
• An even knock, which does not depend on the speed, is caused by the valve-distributor mechanism, which indicates the wear of its elements;
• A distinct short knock, increasing at higher revs, warns of the imminent end of the connecting rod bearing.

This is only a small part of the possible sounds as a result of certain malfunctions. Every Peugeot driver must remember the sound of a normally working engine in order to react quickly to any changes in it.

7. Diagnostics of the cooling system of the Peugeot 408 engine. With proper operation of the cooling system and sufficient heat dissipation, after starting the engine, the liquid circulates only in a small circle through the heater radiator, which contributes to the rapid warming up of both the engine itself and the Peugeot 408 interior in the cold season.

When the normal operating temperature of the Peugeot 408 engine is reached (about 60-80 degrees), the valve opens slightly to a large circle, i.e. the liquid partially flows into the radiator, where it gives off heat through it. In case of reaching the critical level under 100 degrees, the Peugeot 408 thermostat opens to the full, and the entire volume of liquid passes through the radiator.

Together with this, the fan of the Peugeot 408 radiator turns on, it contributes to better blowing out of hot air between the radiator cells. Overheating can damage the engine and require costly repairs.

8. Typical malfunctions of the Peugeot 408 cooling system. If the fan does not work when the critical temperature is reached, then first of all it is necessary to check the fuse, then the Peugeot 408 fan itself and the integrity of the wires to it are examined. But the problem may turn out to be more global, the temperature sensor (thermostat) may have failed.

The performance of the Peugeot 408 thermostat is checked as follows: the engine is preheated, a hand is applied to the bottom of the thermostat, if it is hot, then it is working properly.

More serious problems may arise: pump failure, leakage or clogging of the Peugeot 408 radiator, breakdown of the valve in the filler cap. If problems arose after replacing the coolant, then most likely an air lock is to blame.

»Check engine lit up - what to do?

Check engine lights up - we understand the reasons for the car malfunction

Many owners of light vehicles for the time being do not pay attention to devices and bulbs that do not give "distress signals". The owners of cool foreign cars stuffed with electronics, which stands for Check Engine, do not know.

For us drivers

When a light comes on, at best, drivers ask themselves the question: why did it light up and what to do?

Indeed, what measures need to be taken when?

1. First, there can be several reasons for the light signal to come on.
2. Secondly, the problem often has to be looked for for a long time and one cannot do without computer diagnostics.

A little educational program

Most of the cars that have left the factory gates today are equipped with a check engine mounted on the dashboard.

An active light indicates that it is necessary to check the power unit. The control unit has detected a problem and informs you about it.

In the early 1980s, cars were equipped with mini-computers to control the carburetor. Gradually the field of application expanded. Currently, on cars, the "silent controller", which has undergone a serious evolution, monitors:

• behind the composition of the feed mixture,
• fuel consumption,
• speed of the power unit,
• the moment of ignition.
• controls gear shifting in automatic transmission.

Which of this far from complete list of control functions can you make a logical conclusion? That's right, there are more than enough reasons for the check light to come on.

Consequently: without certain knowledge and practical skills, it is extremely difficult to identify the cause of the warning light coming on.

So what needs to be done, what action to take? Let's figure it out together!

Check engine caught fire , how to proceed?

Did you know,

that the check engine light comes on is an inconclusive verdict of an engine malfunction?

1. If the Check Engine indicator, when starting the power unit, signals problems and immediately goes out, do not worry. Your engine is not susceptible to "technical diseases", is in good condition and cannot be "treated".
2. When you turn on the engine after the light warning appears, the Check Engine does not turn off for a long time - it's worth considering. There must have been problems. They can be large-scale or minor. It is better not to risk it and turn to specialists.

What makes the check engine "blush"?

• If while driving, you notice that the Check Engine light comes on, the likely cause may be an insufficient oil level in the power unit. In this case, it is recommended to make a stop and, without turning off the engine, open the hood to listen to the operation of the unit. If the motor runs smoothly: there is no grinding and extraneous noise or knocking, pay attention to the tightness. You may find smudges on the engine housing. It is recommended to seek advice and resort to the help of service station masters.
• The Check Engine warning light may be related to the spark plugs. Most likely, one of them is out of order (misfire).
• The check is capricious when the fuel is of poor quality, which is often the case when refueling. This problem manifests itself as soon as you leave the gas station.

Consider the options for lighting the Check Engine light and ways to solve problems

About problems and methods of liquidation
	Cause of malfunction	How to fix
1	Low-quality fuel filled.	It is recommended to drain the contents of the fuel tank and refuel with “normal” gasoline or high-quality diesel fuel.
2	Problems with spark plugs: cracked insulator, gap not adjusted, carbon deposits.	Check, replace if necessary.
3	Failure of the ignition coil.	Check the spark with an ohmmeter. The recommended coil resistance at the output is 1–4, 2–3.
4	Lambda probe.	Check oxygen sensor. If it fails, it is recommended to replace it.
5	Catalyst.	Functional check required. If necessary.
6	Injector problems.	Verification is required to find out the reason. Clean if necessary.
7	Fuel pump "junk".	Checking the pressure in the rail. The normal state is up to three atmospheres.
8	Fuel filter problems.	Having found a problem, clean the filter, and or completely replace the gas pump.

This is an incomplete list of reasons that influence the Check Engine light on.

You can eliminate the errors that have occurred without using a diagnostic scanner yourself. Experienced drivers eliminate the error in this way. Unscrew the battery terminals. Put them aside, avoiding a short circuit.

Waiting time is not more than 20 minutes. If, after connecting the battery and starting the power unit, you see a reset clock and an extinguished control check Engine light you have completed the task. However, it must be remembered that in this way accumulated errors are removed. The real problems of the power unit will appear on the second day of vehicle operation.

How to check high voltage wires

The check engine light came on

Could it be high voltage wires? Sometimes it happens.

Advice: follow and follow the instructions exactly.

Fill a saucepan with liquid. You can use a regular saucepan. Necessarily made of stainless steel. Add some salt. 1 tablespoon will be enough. Take a megohmmeter by dipping the wires into the water. The ends should be on the surface.

We connect the device to 1 handpiece. We fix it with a clamp. 2 we put the clamp on the container where the wires are left on the surface of the water. If the resistance shows more than 1 megohm, the insulation is in good condition. In some cases, a value of at least 500 kOhm is allowed. If the indicators are below the critical mark, the wires need to be replaced.

Recommendation: if the methods of self-conducted diagnostics did not give a positive result (the check engine light is still on), specialist intervention is required. And it's urgent! Otherwise, the problems can be massive.

Tips for those on the road

No matter how well you know about cars, but specialists, who are armed with special equipment, understand more about the occurrence of this or that cause of the "alarm". Moreover, service station masters have constant practice, and this experience cannot be taken away!

Experts do not advise to take any measures to eliminate the malfunction if you are not confident in your abilities, it is best to call a tow truck and send the car to the nearest service station.

As a rule, for many car manufacturers, the check engine light comes on when engine malfunctions are associated with a violation of injection and deterioration of exhaust, which will greatly affect the environment.

Diagnostic work is the first step towards identifying possible problems. A brief diagnosis will show what influenced the lighting of the light bulb, and the master will outline the essence of what is happening.

When heading to a service station and driving a car, you must take precautions.

• Do not load the power unit
• Try to drive at a constant speed not exceeding 60 km / h.
• Monitor the speed level. Avoid going beyond the 2500 rpm mark.
• Reduce loads. Somehow disconnect the air conditioning system and other additional equipment. Give up for a while from your favorite multimedia system. Switch off electrical devices that do not affect the normal and safe movement of the vehicle.
• Drive smoothly, avoiding sudden acceleration and emergency braking.
• Plan to drive to the service station during daylight hours. At night, the headlights create additional loads on the power unit. You can move at night, subject to increased attention, in compliance with the above conditions.

Habitual driving style is possible after checking the car and recommendations of the workshop specialists.

And further

It should be understood that the check engine light can come on at any minute. This is not a reason for panic, but only a warning about possible malfunctions. It is not recommended to ignore the check engine warning signal. Since the consequences of neglecting warning devices are fraught with serious consequences.

Diesel will not start, malfunctions and reasons
Instrument panel icons - what they mean Airbag error - airbag light is on Peugeot errors 308, 408, 3008 Why did the diode bridge of the generator burn out? Lamps in Peugeot - Replacing light bulbs in Peugeot

The unstable operation of gasoline engines of the Franco-German development of EP6, which are installed on the Peugeot 308, is quite common. The engine starts to run cold, the fan turns on, the check is on, in a word, there is little pleasant. There are plenty of reasons for this behavior of the motor, it remains for us to consider them and try to find a solution to restore performance.

Why does the fan turn on when the engine is tripled on the Peugeot 308

Check for all possible causes.

A constant fan on, regardless of the coolant temperature in the system, is a symptom of almost any engine problem.

Even with one inoperative spark plug, the fan will blow at maximum speed and this is quite normal in this case. If several more problems are attached to the fan, then it is possible to localize or at least assume the cause of the malfunction.

Here are the main causes of motor vibration (troit and intermittent):

• one of the spark plugs does not work;
• one of the ignition coils does not work;
• misfiring in one particular or in several cylinders;
• air leaks into the combustion chamber;
• failure of the catalyst, incorrect removal of the catalyst without updating the ECU firmware;
• incorrect operation of the gas distribution mechanism;
• poor quality fuel.

Perhaps these are the main reasons for this behavior of the motor, and they will have to be considered individually.

Troit the engine: checking candles and coils

Naturally, when this bunch of faults appears, it is most correct to get to the diagnostic center. There, an accurate check will be carried out on the diagnostic equipment and errors () will be installed. However, at the initial stage, you can carry out diagnostics with your own hands, starting from the readings of the on-board computer, and sometimes without them.

The most common cause of an unstable cylinder is a failed coil, spark plug or nozzle.

Which cylinder is troit (cold test)

We find out which cylinder does not work on cold at idle:

1. Open the hood, remove the plastic head cover.
2. We start the engine.
3. We remove the impulse wires from the ignition coil of each cylinder one by one.
4. If the operating mode of the engine changes sharply when one or another cylinder (coil and) is turned off, then everything is in order with it.
5. Disabling the idle cylinder does not in any way affect the operation of the engine at idle.

Suppose we figured out the number of the idle cylinder.

Spark plug and coil performance

Old candles are one of the possible reasons.

Now it remains to check the performance of the coil and spark plug.

Swap places presumably a non-working coil with a working one and start the motor at idle. Removing the signal wires from these coils one by one, we find out whether the assumptions about the inoperative coil were confirmed - if the healthy cylinder stopped working, the coil is to blame. If the non-working cylinder continues to be silent, the candle is to blame. Conclusion - we replace the ignition coil and, if possible, the plugs in the cylinders.

Attention: when replacing candles, in no case should a new candle be thrown into the well, otherwise there is a danger of knocking down the gap between the electrodes, then the new candle may not work. It is carefully lowered into the well and twisted strictly along the thread with a special key.

If at this stage it was not possible to find a malfunction, we proceed to more radical measures.

Peugeot 308 misfire - what is it?

It is possible to determine gaps in spark formation without diagnostic equipment. Here are the main symptoms:

• engine troit;
• the check is on;
• the fan is constantly running;
• power drops sharply and;
• an error message appears.

On the Peugeot 308, the misfire error codes start with P1336 (misfire, cylinder undefined), in order up to P1340 (misfire in the 4th cylinder).

Actual errors.

There can be a lot of reasons for a pass - from poor-quality fuel to insufficient compression in a certain cylinder. If we have already replaced the candles, everything is fine with the coils, then we measure the compression. Denomination - 12.6-13 atm in each of the cylinders. If the compression is abnormal or one of the cylinders has low compression, this will indicate that compression rings are buried, possible air leaks, malfunctions in the gas distribution mechanism.

Injector problem

Clogged nozzle.

Errors Р1336 – Р1340 can also occur due to a faulty or clogged nozzle.

In order not to remove the ramp, you can check the resistance at the injector leads. This requires a multimeter in resistance measurement mode.

The nominal resistance of the nozzle is 12.6–12.8 Ohm.

You only need to check it at the time of the malfunction. If everything is fine with the resistance, it remains - it is better to do this on a flushing stand with a special liquid.

Timing problem

It is not easy to identify and fix problems with the gas distribution mechanism with your own hands.

To do this, it is necessary to remove the block head and carry out diagnostics visually, as well as measure the valve lift. For example, on an EP6 engine, the valve lift at idle speed is 0.4 mm , and at high speeds - about 4 mm ... The BMW VVTi system is responsible for changing the phases, which is quite difficult to understand.

Frequent breakdown on 308s - misaligned or missing valve seat , carbon deposits on the valve, which will also cause the above errors and symptoms.

Air leaks

Air leaks can appear in several places:

• block head gasket;
• intake manifold gasket;
• suction through the pipes connected to the intake manifold;
• failure or clogging of the EGR valve.

conclusions

Most of these malfunctions are eliminated and diagnosed at the service station, however, the most common and simple problems can be easily eliminated on your own. Keep your engine running smoothly and keep the roads smooth!

Last night, leaving the yard, out of habit, he pressed the gas and got Jackie Chan. There was a squeak and an inscription appeared on the display - "The engine is faulty, repair the engine". Resetting the battery terminal did not help. Signed up for an OD check. This morning I was driving to them, when the car asked for refueling and I decided to refuel before arrival .. After refueling, I start the car and I understand that the check is gone. But still I decided to drive to Peugeot.
The master inspector said that most likely it was due to low-quality fuel or the exhaust gas sensor was buggy, in general they did not check it.
But still, the trip was not in vain because under the guarantee they changed the protective plastic on the door racks. :-D

05.11.2015, 13:31

Vin7421, oh-oh-oh how, our drivers rub their ears that in Ufa salara, God forbid, presses into the back with terrible force: -D. Accordingly, fuel economy immediately went, dvigun immediately like that works smoothly. Hike business you need to slip through in transit: -D.

05.11.2015, 13:47

So before that I did not complain about the quality of the fuel .. Everything was fine. Refueling is strictly Lukoil and sometimes Bashkirnefteprodukt.

05.11.2015, 19:53

All was good. Refueling strictly Lukoil
I spent two years refueling on Lukoil, and then it happened that I was returning from another area at night, a light came on, I had to look for Lukoil, and here at the entrance to Moscow along the Entuziastov highway there is BP, filled a full tank and drove to sleep ... the engine started working more pleasantly and even a bit of hassle, yesterday I repeated refueling at BP again, suddenly it didn't seem like it :)

05.11.2015, 20:07

I don't particularly sin on fuel, and the tank was almost dry already ...

It was nevertheless necessary to count the mistakes. With such symptoms, the cooling fan resistor burned out. From time to time "Check" appeared and sometimes almost immediately, and sometimes after some time, having managed to switch the engine to "safe" mode, it disappeared. After two months and 8 thousand mileage was still replaced under warranty.

07.11.2015, 15:51

It will appear again, I'll go to shoot mistakes, be sure.

10.04.2016, 09:04

Hello!!! I do not know what topic to write, so I decided here! (correct if anything). The problem is the following, as the inscription `` engine malfunction '' and a check, respectively, was displayed, was driving around the city, I did not notice losses in traction, only the sound of the engine was floating. I muffled, threw off the stigma, it took about five minutes to put it on, the check is on, but the engine runs smoothly, after the third plant within 10 minutes the check disappeared. I thought that he didn’t like the fuel, and after that I drove 350 kilometers the check didn’t burn. Yesterday I made a diagnosis and here are the results in the archive: error P0088 excessive pressure in the ramp (instead of the supposed 400-something, it was 1000-something). The error has not yet been repeated and I hope it will not happen again, before I caught the check I slipped and pressed the gas pedal to the floor (there was a need) and immediately drowned it out, then after a couple of hours I started it and drove off. The error has been deleted from the archive! More errors that could not be removed P 2133, P 2134 short circuit to + accelerator pedal. The question can someone enlighten me with a high pressure fuel pump or a pump nozzle, is it worth it for me to prepare to replace the high pressure fuel pump and what is its price, well, advice will be useful, maybe someone has come across or what he thinks about this

10.04.2016, 23:10

we have a high-pressure fuel pump, but I think it has nothing to do with it.
My version: the problem is in the pedal, most likely in it two channels work in parallel for each parameter, which the computer then compares.
excessive pressing damaged one of the circuits, a signal came to the computer according to which it did not correctly issue a command to the pressure control valve.
when turned on again during self-diagnosis, the computer detected a faulty circuit and turned it off.
now works on the remaining healthy circuit and reports an error.
in principle, you can ride, that's okay.
Well, in order to find out the reason, you first need to throw a known working pedal and see if the error goes away.

DV 6C TED4
SIEMENS / VDO DV 6C TED4 system is a modification of systems for DW type engines and is used on a wide range of Peugeot, Citroen, Ford, Volvo, Mazda models with an engine capacity of 1600cc. A distinctive feature is the use of a high-pressure fuel pump with two plungers, which are located vertically at an angle of 180 degrees to each other. The high pressure pump includes a standard transfer pump in the low pressure line, VCV and PCV valves, and can develop a maximum pressure of up to 1600 bar with 200 bar at idle

11.04.2016, 09:59

Thanks! I already thought about trying to change the pedals, but where can I get it not to buy it, the cheapest price is 8200! I have a cruise control knob with a limit, can it conflict and give these two errors p2133 and p2134?

11.04.2016, 21:52

12.04.2016, 10:56

yes indeed, p2133 and p2134 from cruise, looked at myself - the same
Thank you so much!!! I think if you put the joystick without a limit, errors should disappear ...

14.04.2016, 07:56

Last night, leaving the yard, out of habit, he pressed the gas and got Jackie Chan. There was a squeak and an inscription appeared on the board - "The engine is faulty, repair the engine". :-D
One to one, it happened again last night. But the tank was full, just refueled .. But this time resetting the battery terminal helped. I don’t even know to go not to go to OD.

15.04.2016, 08:49

One to one, it happened again last night. But the tank was full, just refueled .. But this time resetting the battery terminal helped. I don’t even know to go not to go to OD.

Make a diagnosis, you need to understand what errors pop up, perhaps the fuel quality is not very good

31.10.2016, 16:02

Please tell me what you can do yourself or what to be ready for. the machine is not under warranty. I calmly drove to the village 135 tons km, turned off the engine. After 5 minutes I turn on the ignition, an error is displayed: "engine malfunction: repair the car". The engine runs quietly, the thrust is not lost, in general, nothing ordinary.
The only thing I have frozen is "non-freezing" summer and I periodically made money on the washer, in the hope that the system defrosted. After a while, I noticed that the pump did not make a characteristic noise. A little later, the pump started working. Even before the trip, I refueled at a suburban gas station "Gazprom", although I always refuel at Gazprom, but at the same one within the city. Therefore, I sin on fuel, but again the engine runs smoothly. And the last thing I noticed is that the head unit is very hot. During the trip back to the city, the radio spat out the disc, the disc was very hot, even with the radio turned off, the disc inside was heating up, the plastic near the radio was very warm, and a little further cold. Hence the dumka, maybe it is shorting somewhere?

31.10.2016, 16:26

Grifq, I would start with diagnostics, see what the error is, and then on the results. Is the radio working or not? The radio can get very hot due to the short circuit of the wires to the speakers between themselves or to ground. Are the speakers and wiring to them standard? If changed to others, check for a short circuit, at least visually. It is not uncommon for speakers with a greater landing depth to be installed and the wires from them cling to the glass when it is lowered. Could tear off the wire from the speaker and short to ground ...

31.10.2016, 16:47

Everything is regular, nothing has been done and has not changed

31.10.2016, 16:50

I calmly drove to the village 135 t. Km,
However, your village is not close * CRAZY *
In general, of course, you need to start by reading errors and already build on from this.

31.10.2016, 16:58

I hope it won't be expensive ...

31.10.2016, 22:46

In general, in the evening the "check" disappeared. However, the radio tape recorder is buggy, it reads disks and a flash drive, it does not read. The radio is on. Perhaps because of the weather, wires, or something else that's damp, I don't know. An entry in the engine fault log was not saved, in any case, it is no longer displayed on the display.

31.10.2016, 23:52

01.11.2016, 11:41

135 km)) I started talking about the radio tape recorder because it began to glitch in front of the "check" icon. The disc is very hot, or rather not normally hot. It is clear that it is warming up, but it also warmed up (now it is no longer) even with the radio turned off. I also specifically turned on the cold stream without a stove, and the turned off radio tape recorder (the radio was also off) remained hot. In general, I will not scan anything, until the next "check". The radio tape recorder seems to have worked.

Many of us have faced such a problem as the inclusion of an indication of the engine icon (Check engine ...), the appearance of which scares car drivers. Here are the 5 most common reasons why an engine check comes on on the dashboard.

The engine gauge icon usually appears without warning. The reason for the appearance of the Check engine cannot be immediately understood. Even if there is an auto diagnostics in the car (for example, in such cars as,), which scans all systems of the car for errors and, if any, displays a decryption on the information panel, the reasons for the appearance of the engine check will not be decrypted.

For most drivers, the appearance of this warning symbol on the dashboard means that they urgently need to go to a car workshop to diagnose and eliminate the cause of the engine check warning sign. But in fact, in most cases, when the "Check" indication appears, it is possible, and in some cases, perhaps, to eliminate the cause on your own without a trip to a car service, which will save your money.

1. Replace the oxygen sensor (lambda probe)

The oxygen sensor in your car is part of the exhaust gas system that monitors how much oxygen is not burned out in the engine's combustion chamber. This sensor helps to monitor the fuel consumption of the vehicle. A malfunctioning oxygen sensor (lambda probe) means that the car computer receives incorrect data, which can significantly increase fuel consumption and reduce engine power. Most cars have 2 to 4 oxygen sensors. If you have a home car error scanner, then by connecting it to the car, you can easily find out which sensor needs to be replaced.

For what reason the oxygen sensor in the car becomes unusable: Over time, the sensor becomes covered with a layer of used and engine oil (oily soot), which reduces the accuracy of the sensor readings to regulate the gasoline mixture and distribute the optimal one. A malfunction of the oxygen sensor in the car leads not only to, but also to an increased content of harmful substances CO2 in the exhaust.

What needs to be done: If you do not replace a faulty car oxygen sensor, then this can lead to the failure of your car's catalyst (may burst), which will result in expensive repairs. The cost of new catalysts is very high due to the content of precious alloys in them. On some cars, there are several catalysts, the cost of which can go up to 90,000 rubles. So do not delay replacing the sensor. Although the replacement of the sensor and its cost is not very small, it is incommensurate with the cost of the exhaust gas neutralizer system. You can also save on replacement costs by doing it yourself. Many car manuals have detailed instructions on how to replace the oxygen sensor yourself. If you know where the oxygen sensor is, then it will not be difficult for you to disconnect the faulty "lambda probe" and replace it with a new one. Remember that you cannot pull to replace this important element!

2. Check the fuel filler cap

Many drivers in most cases, when the "check engine" indication appears, will think about serious problems in the car's engine, but will not even think to check the tightness of the fuel system, which may be broken due to a defect or insufficiently tightened fuel filler cap. This is a very common cause of the "Check" engine icon.

The reason for the error: Leakage of the fuel system due to the passage of air, the fuel filler cap, will increase the fuel consumption of the car, for which the car diagnostic system will give an engine error by turning on the "Check engine" indication on the dashboard of the car.

What needs to be done: If, when the "Check" indication appears, your car has not lost power, and there are no sound signs of engine damage (knocking in the engine, hum, creaking, etc.), then first of all check the tightness of the gas tank. Your gas cap may be cracked or not tight enough. If the cover was not tight enough, then after tightening it all the way, continue driving the car for a while to see if the engine error disappears. To prevent an engine check from appearing for this reason, regularly check the fuel filler cap. Remember that periodically the cover must be replaced with a new one!

3. Car exhaust gas catalyst

The car catalyst helps the car to make the engine exhaust gas cleaner. It converts carbon monoxide and other harmful substances into harmless compounds. If your exhaust gas catalyst has become unusable, you will notice this not only when the engine badge (check) appears, but also long before that, when the car's power drops by 2 times. For example, when you press the gas pedal, the car, as before, will not have good acceleration dynamics.

Because of what the automobile catalyst can fail: if you regularly service your car, in accordance with the maintenance regulations of the car company, then the catalyst should not fail. The main reason for the failure of the catalyst is the untimely replacement of a faulty oxygen sensor, as well as irregular replacement of spark plugs at the end of the expiration date. When the oxygen sensor or spark plugs are faulty, the conversion of carbon monoxide in the catalyst into harmless chemical elements stops, which leads to overheating of the catalyst, which can fail as a result.

What needs to be done: If your catalyst has become unusable, then you cannot drive the car, since the engine will not work correctly, warning about this by an indication on the dashboard with an engine icon (check). Also, your fuel consumption will be greatly increased, and there will be no engine thrust. Although replacing a catalyst is a very expensive repair, there is nowhere to go from repairs. Although there is an alternative to replacing the catalyst with a flame arrester, this is not a 100 percent option. Unfortunately, if you are not an experienced auto mechanic, you will not be able to replace a faulty exhaust gas catalyst yourself. In any case, you will have to go to a car repair shop. Remember that timely replacement of oxygen sensors and spark plugs protects your catalytic converter from damage!

4. Replace MAF sensor

The mass air flow sensor regulates how much air must be added to the gasoline mixture for optimal fuel ignition. The sensor continuously informs the vehicle computer of the amount of oxygen supplied. A defective MAF sensor increases fuel consumption, increases CO2 levels in the exhaust gas, and decreases engine power and ride comfort. Also, with a faulty sensor, poor acceleration dynamics is observed. In cold weather, a car with a faulty sensor will not start well.

What are the reasons for the failure of the mass air flow sensor: Most sensor failures occur due to improper installation of the air filter during its scheduled replacement. Also, if you do not regularly change the air filter, as required by the vehicle maintenance schedule recommended by the manufacturer, the MAF sensor may fail.

What needs to be done: In theory, you can drive for a long time with a broken MAF sensor (several weeks or months). But you will notice that the longer you drive, the more fuel consumption increases. Replacing a sensor in a car service is not that expensive, since the work itself does not take much time and is quite simple. The main costs are related to the cost of the sensor, which for some car models can be 11,000-14,000 rubles if it is an original sensor or up to 6000 rubles if it is an analog substitute. Replacing the sensor yourself is very easy. But due to the low cost of replacing the sensor, you can entrust this work to the master in the car service. Remember that you need to regularly change the air filter, observing the vehicle maintenance regulations!

5. Replacing spark plugs and high voltage wires

Spark plugs in a car are the main parts for igniting the fuel mixture. With faulty spark plugs, the spark is incorrectly supplied to ignite the gasoline mixture. In faulty spark plugs, there is often a lack of spark or an incorrect spark interval, which affects engine malfunction. If the spark plugs do not work properly during acceleration, especially from a standstill, you may feel small jolts.

What are the reasons for the failure of spark plugs: Most spark plugs in vehicles prior to 1996 need to be replaced every 25,000-30,000 kilometers... In newer cars, spark plugs last over 150,000 km. However, these spark plug replacement times can be reduced due to various factors related to fuel quality and driving style.

What needs to be done: If your spark plugs have not changed for a long time, or you feel dips associated with ignition in the engine, then you must immediately replace them with new ones without delay. Do not try to save money on untimely replacement of spark plugs, as the cost of spark plugs is not very expensive, as well as the work of replacing them. Replacing old spark plugs will improve engine performance and reduce vehicle fuel consumption. Replacing spark plugs yourself is easy enough. Mostly they are easily accessible under the hood of the car. You need a regular spark plug wrench to remove the spark plugs from the engine. It is also advisable to monitor the condition of high-voltage wires, since over time they can become unusable and allow electricity to pass, which is transmitted to the spark plugs, which will reduce the strength of the spark. Remember that regular replacement of spark plugs, in accordance with the maintenance schedule of your car, keeps your exhaust catalyst from damage, and also improves engine performance!
