What is wrong with epc yellow light?

The yellow light of epc indicates that the power control and management system of automobile engine has failed.

Generally speaking, the common fault of EPC light is that the throttle valve is dirty, or the brake light is not on or the oil used is not good, which leads to the EPC fault light.

The solution is to clean the throttle, or check whether the brake switch and circuit are normal, and then eliminate the fault.

If the EPC fault light appears, it indicates that there is something wrong with the engine power control management system. The main reasons for this problem are as follows:

The first one is that the brake lights don't work. When the brake light of our vehicle is not on, the EPC fault light will appear.

Second, the throttle fails. If there is something wrong with the throttle or wiring of the engine, EPC will also light up.

Third, the brake switch is damaged. If the brake switch is damaged and fails due to excessive wear, EPC will also appear.

The fourth is that the clutch switch is broken. Like the brake switch, EPC will appear when the clutch switch is broken.

What's the problem? I suggest you use the maintenance computer to check and find the problem according to the fault code.
