What does the EPC warning light mean?
1 Answers
The EPC warning light stands for the Electronic Power Control system of the engine. After starting the engine, the vehicle begins a self-check, and the EPC indicator light will illuminate for a few seconds before turning off, which is a normal phenomenon. If the EPC light remains on after the vehicle starts, it indicates a malfunction in the vehicle's mechanical or electronic systems. Generally, an illuminated EPC light could mean that the throttle body is dirty and needs cleaning, or it could indicate that the brake lights are not working, requiring inspection of the brake switch and wiring. EPC, or Electronic Power Control, is also commonly referred to as Electronic Stability Control. This system consists of components such as sensors and controllers. When a sensor malfunctions or detects an abnormal condition, the control system will take appropriate measures based on pre-set programs.
