What does it mean that the automobile instrument shows EPC yellow light?

EPC = electronic power control (full name of engine electronic stability system), which is also called electronic throttle by many people.

Generally speaking, there are three possibilities for EPC lights to light up. First, the throttle is dirty and needs cleaning. In one case, the brake light is not on, so it is necessary to check the brake switch and wiring. Also, due to the oil problem, the EPC fault light will also light up.
