My Ming Rui has an exhaust emission control indicator light. What is the reason? How to rule it out?

1, you should find a safe place to stop and check whether the engine has abnormal sound and oil leakage. If there is no abnormality after the inspection, it may be a false alarm of fault induction lamp. When the pollution light is on, the engine will not shake or slightly shake. At this time, the owner does not need to worry when using it. It can be used normally, and sometimes it can be checked or maintained when it is convenient.

2. Generally speaking, the fault lights of vehicles are caused by the fuel discharge system. Start and stop the vehicle when the fault light is on. After starting the vehicle three times, observe whether the fault light is still on. If it is still on, you need to go to the store to check the fault code in time to see if it is an engine fault or a sensor fault.

Extended data:

Causes of engine exhaust system failure;

1, the engine exhaust system fault light comes on, mainly because the throttle valve or the engine has too much carbon deposit, resulting in unbalanced mixing ratio, so when the engine computer monitors some signals that affect the emission requirements, the fault light will appear.

2. When the engine is at low speed, often hanging high gear will lead to this phenomenon.
