EPC is the fault indicator light for the vehicle's mechanical and electronic control system. When the car displays EPC, it means there is a malfunction in the engine's power control management system, requiring troubleshooting and repair. The following are specific reasons for the appearance of EPC: 1. Intake system issues: Faults, leaks, or blockages in the intake system. 2. Throttle problems: Dirty throttle body, excessive carbon buildup, etc., causing the EPC fault light to illuminate. 3. Poor fuel quality: Substandard or poor-quality fuel. 4. Cylinder pressure issues: Abnormal cylinder pressure, poor operating conditions.
