What is the fault of automobile display epc?

The car EPC light is on, which is an electronic throttle fault.

Several possibilities of causing EPC lamp to light up;

1. Check the electronic throttle. If there is dirty carbon deposit in the throttle, it may cause the EPC light to light up.

2. The air intake system leaks or is blocked badly.

3. The fuel added by the car is unqualified.

4. Abnormal engine cylinder pressure leads to poor working conditions.

5. Unexpected failure and false alarm of the system lead to the lighting of EPC lamp.

Treatment of sudden lighting of EPC indicator light during driving

Park the vehicle in a safe place, put out the fire first and then restart the vehicle, and observe whether the EPC indicator light is still on. If EPC is not turned on, there is generally no problem, which may be a false alarm caused by sensor interference; If it is still on, the owner must first check whether the brake light of the vehicle can be on.

If the brake light can be turned on, the owner should go to the official service station as soon as possible to test it with special instruments. If the brake light goes out, but the brake system works normally, it may be because the brake light bulb is broken and you can drive normally, so it will be fine to replace it with a new light bulb in the future.
