Engine emission control What is the reason why the fault light of the system is on?

The fault light of the engine exhaust system is on. The main reason is that there is too much carbon accumulation inside the throttle valve or engine, resulting in the misalignment of the mixing gas ratio. When the engine computer detects some signals affecting the emission requirements, the fault light will turn on. Like.

There may be many reasons why the engine emission fault light turns on. First of all, it may be due to a failure of the engine's fuel system or ignition system, such as poor oil quality or oil blockage.Secondly, it may also be due to a failure of the sensor or actuator, causing the engine to not work properly.

The reason why the emission fault light is on: the fuel combustion condition is not good, the fuel is not burned or burned insufficiently, the engine bursts, and the temperature inside the engine is too high. Clean the throttle valve.

The fault light of the engine emission adjustment system is a problem of the fault of the emission system caused by the unstable working condition of the automobile engine.

The common problems of engine emission failure are as follows: poor contact with the engine sensor makes the car's acquisition of engine data inaccurate. Fuel was not added according to the automobile fuel standard, resulting in insufficient combustion of the mixed gas in the engine. The driver's irregular operation behavior increases the operating burden of the engine.

[TooPingyang Automobile Network] Most of the engine exhaust system fault lights are 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 turns on while driving, please slow down immediately and drive to the nearest maintenance service station for maintenance.

Engine exhaust system fault light

If the exhaust system fault light is on, it may be that the oxygen sensor is broken or the ternary catalyst is broken. After the fault light of the exhaust system is turned on, the fault code should be read to confirm the faulty part, and then replace the damaged accessories. There are aerobic sensors and ternary catalysts in the exhaust system of automobiles.

The reasons why the engine exhaust system fault light is on are: the quality of car gasoline is poor and the oil is poor, which may lead to abnormal mixing ratio, electronic equipment failure and abnormal exhaust system. The failure of electronic components of the air intake system, such as oxygen sensors, carbon tank solenoid valves, throttle valves, engine carbonisation, etc.

When the engine exhaust system fault light lights up, the first step should be to slow down and find a safe place to park and check.The fault light may be due to problems with one or more components in the exhaust system, such as oxygen sensor failure, catalyst damage or exhaust pipe leakage.

How to solve the engine exhaust fault light

1. How to deal with the exhaust fault light: The indicator light of the exhaust emission control system will light up when the ignition switch is turned on. After starting the engine, the indicator light The indicator light must be turned off.

2. 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 it. 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.

3. CleanTrottle valve If you often drive a vehicle, too much mileage will cause the vehicle throttle to become dirty, causing the engine exhaust system fault light to turn on. Therefore, you should clean the accelerator of the vehicle regularly. It is recommended to clean the vehicle every 20,000 kilometers, which can effectively prevent the exhaust system from turning on.

What is the reason why the fault light of the engine emission control system is on

The fault light of the engine exhaust system is on, the main reason is that there is too much carbon accumulation in the throttle valve or inside the engine, resulting in the misalignment of the proportion of the mixed gas. When the engine computer detects some signals that affect the emission requirements, the fault light will turn on.

The reason why the emission fault light is on: the fuel combustion condition is not good, the fuel is not burned or burned insufficiently, the engine bursts, and the temperature inside the engine is too high.Clean the throttle valve.

The fault light of the engine emission adjustment system is a problem of the fault of the emission system caused by the unstable working condition of the automobile engine.

The common problems of engine emission failure are as follows: poor contact with the engine sensor makes the car's acquisition of engine data inaccurate. Fuel was not added according to the automobile fuel standard, resulting in insufficient combustion of the mixed gas in the engine. The driver's irregular operation behavior increases the operating burden of the engine.

[Pacific Automobile Network] Most of the engine exhaust system fault lights are 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 turns on while driving, please slow down immediately and drive to the nearest maintenance service station for overhaul.
