What does it mean to check the engine emission control system

1. Please check the emission system means that the engine's emission system is faulty; when our vehicle fails, these faults will form a series of codes. After the ECU reads the fault code, it will It is displayed on the electronic dashboard in the form of an indicator light.

2. It means that the emission system is faulty. It may be a failure of the fuel supply system, ignition system, etc., the engineOverheating and tempering, resulting in the sintering and peeling of the ternary catalytic converter carrier, and the increase of the exhaust resistance, etc. The specific reasons and solutions are as follows: Most of the fault light of the engine exhaust system is caused by the quality of the oil.

3. Checking the engine emission control system is a problem of the engine emission system. After a failure, the exhaust emissions of the car will increase, and the power performance of the engine will also decrease. The automobile exhaust system mainly discharges the exhaust gas discharged by the engine, and can also reduce the emission of pollutants and reduce the noise generated by the engine during operation.

What does the failure of the engine emission control system mean

The failure of the engine emission control system refers to the problem of the engine emission system. After a failure, the exhaust emissions of the car will increase, and the power performance of the engine will also decrease.The automobile exhaust system mainly discharges the exhaust gas of the engine, which can also reduce the emission of pollutants and reduce the noise generated by the engine during work.

The failure of the engine emission control system refers to the problem with the engine emission system. After the failure, the exhaust emissions of the car will increase and the power performance of the engine will also decrease.

The failure of the engine emission system indicates that the exhaust system has failed. It may be due to failures such as oil supply system and ignition system, overheating and temping of the engine, resulting in sintering and peeling of the ternary catalytic converter carrier, increasing exhaust resistance, etc. You can go to the 4S store for specific inspection.

How to solve the failure of the engine emission control system

The failure of the automobile emission system can be solved by restarting the car and then turning off the engine three times in a row, or unplugging the negative pole of the engine battery and waiting for 30 seconds before connecting it. The failure of the engine emission control system means that the engine exhaust system has failed.

The handling method is as follows: the fault light of the engine exhaust system is mostlyDue to the damage of 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.

When the engine emission fault light is on, first of all, keep calm and don't panic. The following is my personal opinion on solving the problem of the engine emission fault light: First, observe the color and shape of the fault light. If the fault light is yellow and there is an exclamation mark, it usually means that the discharge system is faulty.

The internal fuel combustion of the engine is not good, and the high-quality smoke oil needs to be replaced and the throttle valve needs to be cleaned. The quality of the gasoline used is not good, and it is necessary to change the gas station to add fuel. The low-carbon on the top of the piston of the engine is cleaned up the carbon part.The oxygen sensor of the vehicle is faulty and needs to be replaced.

The failure of the engine exhaust system may be caused by damage to the oxygen sensor or the failure of the ternary catalyst. If it is caused by a ternary catalyst failure, only the ternary catalyst needs to be replaced. If it is caused by damage to the oxygen sensor, the oxygen sensor needs to be replaced. There is a ternary catalyst at the head of the exhaust pipe of the automobile engine, which is used to purify the exhaust gas.
