Exhaust system fault light is on. What's going on here?

The automobile exhaust system mainly discharges the exhaust gas from the engine, and at the same time reduces the pollution and noise of the exhaust gas.

The related reasons leading to the lighting of the exhaust system fault lamp are as follows.

First, the vehicle engine has too much carbon deposit, and the three-way catalyst of the exhaust system is blocked, which leads to the fault light. In this case, it is necessary to clean the carbon deposit in the throttle and engine and clean the three-way catalyst.

In general, the recommended cleaning cycle of three-way catalytic converters is about 30,000 to 40,000 kilometers.

Secondly, this phenomenon is caused by the problem of fuel quality. In this case, it is necessary to clean the oil circuit. Under normal circumstances, it is suggested to add gasoline and fuel additives to regular gas stations for corresponding relief.

Thirdly, this phenomenon caused by the failure of sensors related to the exhaust system is mostly caused by oxygen sensors. It is necessary to read the fault code of exhaust system by computer. If there is something wrong with the oxygen sensor, you can directly replace the damaged sensor to solve the problem.
