Engine emission fault light is on, how to solve it

For the causes of engine emission failure, we can Avoid problems through the following ways. For example, maintain and repair the car regularly and in a timely manner; correct bad driving habits; go to a regular gas station to refuel, and add qualified gasoline according to the car fuel standards, etc.

The ways to solve the problem that the engine emission fault light turns on include - timely maintenance of the vehicle, inspection and replacement of the filter. - Check whether the gasoline pump is working normally, and determine whether there is any abnormality in the gasoline injection. - Check whether the amount of oil is normal, and if necessary, add the correct oil brand.

Start and turn off the vehicle three times in a row, or unplug the negative pole of the engine battery, wait for 30 seconds before connecting. After completing the above method, check whether the engine fault light on the dashboard is still on. This method is only for false engine failures.

The solution to the engine emission fault light is to read the fault code to confirm the fault part, and then replace the damaged accessories. The fault light of the engine emission system indicates that the engine system is faulty. It should be checked and repaired in time to avoid the consequences of deterioration of vehicle performance, reduced kinetic energy, and shortened engine service life.

The topic I want to talk about today is how to solve the engine exhaust exhaust fault light after it turns on? If the exhaust emission warning light occasionally turns on during the use of the car, many of the reasons are that the fuel quality does not meet the standard, resulting in insufficient combustion of the engine mixture.

The topic I want to talk about today is how to solve the engine exhaust exhaust fault light after it turns on? If the exhaust emission warning light occasionally turns on during the use of the vehicle, many reasons are that the fuel quality does not meet the standard, resulting in insufficient combustion of the engine mixture. In this case, when choosing a gas station, you can go to small gas stations as little as possible.

How to solve it after the engine exhaust exhaust fault light is on

1. In addition, avoid refueling after changing the oil at the gas station. After refueling, you can add some good quality fuel additives to improve the quality of fuel. .

2. In addition, it can also prevent the gas station from refueling after changing the oil. After refueling, you can add some good fuel additives to improve the quality of fuel.

3. The solution to the problem that the car exhaust exhaust fault light is always on is as follows: start and turn off the vehicle three times in a row, or you can unplug the negative pole of the engine battery and wait for 30 seconds before connecting. After completing the above method, check whether the engine fault light on the dashboard is still on.

4. After refueling, you can add some good fuel additives to improve the quality of the fuel. If the exhaust light is always on, it is necessary to check the current fault storage in the engine with a special detection instrument, and further check according to the content of the fault storage and the data status of the engine oxygen sensor and other systems.

What is the reason for the engine emission fault warning light on

1. The reason for the engine emission fault light alarm: it may be a fake fault; the quality of domestic oil products causes damage to the oxygen sensor of the ternary catalytic system or the poisoning of the ternary catalytic converter; it may also be a fuel pump or Caused by the failure of the ignition device. The reasons for the alarm of the engine emission fault light are as follows: the engine has a false fault.

2. The specific situation analysis is as follows; sensor problems;The sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or signal interruption, the ECU of the car cannot accurately obtain the engine data, which will cause the engine fault light to light up.

3. The throttle valve is a serious carbon inside the engine, and the engine computer will detect the signal, so that the fault light will turn on. The fuel used by the vehicle is of poor quality and the parking time is too long to deteriorate.

4. The fault light of the engine exhaust system is mostly caused by damage to the oxygen sensor in the ternary catalytic system or the poisoning of the ternary catalyst caused by the quality of domestic oil products. If the light lights up while driving, please slow down immediately and drive to the nearest maintenance service station for overhaul.
