What happened when BYD f0 engine light suddenly lit up?

BYD F0 (view the transaction price | detailed description of the vehicle) The reasons why the engine light suddenly lights up are: 1, the throttle valve is too dirty, resulting in too thick mixture; 2. Excessive carbon deposition in the engine leads to unqualified exhaust emission; 3. Engine oxygen sensor failure.

BYD F0 engine fault light is on: Vehicle fault light is usually caused by fuel emission system. When the fault light is on, start and stop the vehicle, and then start the vehicle three times. Observe whether the fault light is still on. If it is still on, you need to go to the 4S shop to check the fault code in time to see if it is an engine fault or a sensor fault.

There are two situations when the engine fault light is on:

One is a yellow symbol light, indicating that the engine has a fault, but this fault does not affect the normal work of the engine, but it must be repaired; Generally, in automobile design, in order to ensure that the engine is in good working condition and the normal working life of the engine, an oxygen sensor is designed and installed on the engine to monitor the combustion state of the engine. Once the engine is in a bad combustion state, it will not only pollute the environment, but also cause fuel waste and excessive engine wear.

The other is a red symbol light. Under normal circumstances, it means that the engine has a serious fault and needs immediate maintenance. If it is under special road conditions, it can be exercised in an emergency, but it is necessary to pay attention to the working state of the engine at all times.
