Many of us have come across such a problem as the inclusion of the engine icon indication (Check Engine ...), the appearance of which scares car drivers. We offer you the 5 most common reasons for which the engine check lights up on the dashboard.
The appearance of the engine indication icon occurs, as a rule, without warning. The reason for the appearance of Check Engine cannot be immediately understood. Even if there is a car diagnostic in the car (for example, in such cars, as,), which scans all the car systems on errors and when they are presented, displays the decryption to the information panel, the causes of the engine check will not be decrypted.
For most drivers, the appearance of this warning icon on the instrument panel means the need to urgently go to the auto repair shop to diagnose and eliminate the reasons for which the warning sign "engine check" appeared. But in most cases, in most cases, when the "Check" appears, it is possible and in some cases, it is possible to eliminate the cause independently without a trip to the car service, which will save your money.
1. Replace oxygen sensor (lambda probe)
The oxygen sensor in your car is part of the exhaust exhaust system, which controls how much oxygen has not burned in the engine combustion chamber. This sensor helps to control the fuel consumption of the car. The oxygen sensor malfunction (lambda probe) means that the automotive computer receives not the correct data, which can significantly increase fuel consumption and reduce engine power. Most cars have from 2 to 4 oxygen sensors. If you have a home automotive error scanner, then you, by connecting it to the car, can easily find out what sensor must be replaced.
For whatever reason, the oxygen sensor in the car comes into disrepair: Over time, the sensor is covered with a layer of spent and engine oil (oil soot), which reduces the accuracy of the sensor indicators for adjusting the gasoline mixture and the optimal distribution. The fault of the oxygen sensor in the car leads not only to, but also to the increased content of the harmful substances of CO2 in the exhaust.
What needs to be done: If you do not change the faulty automotive oxygen sensor, then this may lead to the failure of the catalyst of your car (can burst), which will turn into expensive repairs. The cost of new catalysts is very high due to the content of precious alloys in them. On some cars, catalysts several pieces whose cost can reach up to 90,000 rubles. So do not pull with the sensor replacement. Although the sensor replacement and its cost is not very small, but it is incommensurable with the cost of the exhaust gas neutralizer system. You can also save on a replacement by making it yourself. Many auto operating manuals have detailed instructions, as you can independently replace the oxygen sensor. If you know where the oxygen sensor is located, then you will not be much difficult to disconnect the defective "lambda probe" and replace it with a new one. Remember that it is impossible to pull with the replacement of this important item!
2. Check the fuel tank neck
Many drivers in most cases, when the "engine check" appears, will think about serious problems in the car engine, but they will not even think to check the tightness of the fuel system, which can be broken due to a defect or not sufficiently tightened with a fuel tank. This is a very common cause in the appearance of the engine "Check" engine.
Cause of error appearance: The leakage of the fuel system due to air transmission, the fuel tank fuel cap will increase the fuel consumption of the car, to which the car's diagnostic system is issued an engine error by turning on the "Check Engine" indication on the instrument panel of the automotive instruments.
What needs to be done: If, when the "Check" appears, your car has not lost power, and there are no sound signs of engine damage (knock in the engine, hum, creak, etc.), then check the tightness of the gas tank. It is possible that the lid of your fuel tank has cracks or is not tightened enough. If the lid was not tightened enough, then tightening it to the end, continue the car by car for a while to watch the engine error disappear. In order to prevent the occurrence of the engine check for this reason, check the fuel tank neck cover regularly. Remember that periodically the cover must be changed for a new one!
3. Car exhaust gas catalyst
The car catalyst helps the car make the exhaust of the motor exhaust gases are more environmentally friendly. It converts carbon monoxide and other harmful substances in harmless compounds. If your exhaust exhaust catalyst has become unusable, you will notice it not only when the engine icon appears (check), but also long before that when the car's power falls 2 times. For example, when you press the gas pedal, the car, as before will not have good overclocking dynamics.
Due to which the automotive catalyst may fail: If you regularly serve your car, in accordance with the regulations, the automotive company, then the catalyst should not fail. The main reason for the failure of the catalyst is the late replacement of a faulty oxygen sensor, as well as not regular replacement of spark plugs, at the end of the expiration date. When the oxygen or spark plug sensor is faulty, then the conversion of carbon monoxide in the catalyst in harmless chemical elements is terminated, which leads to overheating of the catalyst, which due to this may fail.
What needs to be done: If your catalyst has become unusable, then you cannot ride a car, since the engine will not work correctly, warning about this indication on the dashboard of the engine icon (check). Also, you will be very much increased fuel consumption, and the engine will be missing. Although the catalyst replacement is very expensive repair, it is not where not to go from repair. Although there is an alternative to replacing the catalyst on the planeencitel, but this is not 100 percentage option. Unfortunately, if you are not an experienced car mechanic, you cannot replace the defective exhaust gases catalyst yourself. In any case, you will have to contact the car repair shop. Remember that the timely replacement of oxygen sensors and spark plugs protect your catalyst from breakdown!
4. Replace air consumption sensor
The air consumption sensor adjusts how the amount of air must be added to the gasoline mixture for optimal fuel ignition. The sensor constantly reports the car computer data on the amount of oxygen supplied. The faulty mass flow sensor increases the fuel consumption, increases the CO2 level in the exhaust gas, and also reduces the engine power and the smoothness of the stroke. Also, with a faulty sensor, there is a bad overclocking dynamics. In the cold time, the car with a faulty sensor is badly started.
What are the reasons for the failure of the mass flow sensor: Most sensors breakage occur due to improper installation of the air filter when it is planned. Also, if you do not regularly change the air filter, as required by the car maintenance regulation recommended by the manufacturer, the mass flow sensor can fail.
What needs to be done: Theoretically you can ride a broken air flow sensor for a long time (several weeks or months). But you will notice that the longer you drive, the more fuel consumption consumption increases. Replacing the sensor in the car service is not as expensive, since the work itself does not take much time and is sufficient. Basic costs are related to the cost of the sensor, which on some cars can be 11,000-14,000 rubles, if it is an original sensor or up to 6000 rubles, if an analog substitute. Independent sensor replacement is very simple. But due to the small cost of work on the replacement of the sensor, you can entrust this work and the master in the car service. Remember that you need to regularly change the air filter, observing the regulation of the car!
5. Replacing the spark plugs and high-voltage wires
Spark plugs in the car are the main details to ignite the fuel mixture. With defective ignition candles, the spark is incorrect for inflammation of the gasoline mixture. In defective candles, there is often no spark or incorrect spark interval, which affects the improper operation of the engine. With the wrong work of the candles during acceleration, especially from the scene you can feel small shoes.
What are the reasons for the failure of the spark plugs: Most of the spark plugs in cars until 1996 release must be changed every 25,000-30,000 kilometers. In newer, the ignition candles are more than 150,000 km. However, these terms of planned replacement of spark plugs may decline at the expense of various factors associated with fuel quality and driving style.
What needs to be done: If your candles did not change for a long time, or you feel in the work of the engine failures associated with the ignition, then it is necessary to immediately replace them with new ones. Do not try to save on a late replacement of spark plugs, since the cost of candles is not very expensive, as well as work to replace them. By changing the old spark plugs, you will improve the engine operation and reduce the fuel consumption of the car. Independently change the spark plugs quite easily. Mostly they are in easy accessibility under the hood of the car. You need an ordinary candle wrench to unscrew the candles from the engine. It is also desirable to monitor the state of high-voltage wires, since over time they can come into disrepair and pass electricity, which is transmitted to the ignition candles, which will reduce the spark strength. Remember that the regular replacement of the candles, in accordance with the regulatory of the maintenance of your car, retains your exhaust gas testing catalyst from breakdown, and also improves the operation of the engine!

Many ask what to do if on the panel caught "Check" Engine? Most drivers at least once heard about such a thing as the "Check" or Check Engine. But someone faces it literally every day, and someone may have never seen someone else.
Check Engineor "receipt" If you translate literally, means "Check the engine". This is just a signal lamp of the OBD-2 system, installed on the instrument panel of most modern cars. It looks different, but most often in the form of a symbolic image of a yellow engine.
This lamp is associated with an electronic control unit (ECU) of the engine, and lights up when information about any error or malfunction appears in the ECU. With good car lamp "Check Enin" It should light up when the ignition is turned on, but go out after starting the engine. If after starting the engine lamp blinks or burns constantly, then there is any malfunction. And in modern cars "Check Enin" It may be included not only if the engine system malfunction is malfunction, but also the automatic transmission control systems, electronic security systems, etc.
What to do if when starting the engine caught fire "Check"?
To begin with, you should not panic. In most cases "receipt" It lights up due to non-critical problems, for example, due to refueling fuel or single ignition passes in one of the engine cylinders.
But it is not worth relaxing either.
To begin with, stop the car and turn off the engine. Open the hood and check the engine oil level. Visually inspect the integrity of all systems and elements under the hood, check if there are no cliffs from wires going to the engine sensors. If the fault failed to find, disconnect the battery from the vehicle for 10 minutes.
Then turn it on and try to start the car. If a Check Engine Still burns, you need to get to the nearest service station, where you can scan the ECU for errors and see what the reason for the lighting of the lamp.
Do not take an example from people who are moving with a burning lamp for months "Check Enin"The principle of "rides and okay". Yes, in most cases, even with a burning lamp, the car remains on the go, but at the same time its systems work in the backup mode.
At best, this will lead to an increase in fuel consumption, power drop, etc. In the worst case, will lead to repair. For example, if the lamp "Check Enin" It burns due to skips of ignition of a faulty candle, then soon, if the ECU does not turn off the fuel supply to this cylinder, this may lead to the inclusive gasoline and its pairs will fail the catalyst, which will lead to expensive repairs.
Therefore, if you have caught Check, do not cost to postpone with the diagnosis. It is worth an average of 500-1000 rubles.
In addition, now there are inexpensive USB and Bluetooth adapters, with which you can carry out such diagnostics yourself without any problems.
