What to Do When the EPC Light Comes On in a Car?

[DeSabrina]

When the EPC light comes on in a car, the following solutions can be applied: 1. Check if the intake system has any faults; 2. Use high-quality fuel; 3. Inspect the electronic throttle body for excessive dirt and clean the throttle if necessary; 4. Remove carbon deposits from related components; 5. Rewrite the ECU-related data. The EPC in a vehicle stands for the Engine Power Control system, also known as the electronic throttle. When the EPC light appears, it indicates a fault in the electronic throttle. Possible causes include: 1. Brake light not functioning; 2. Throttle or wiring issues; 3. Damaged brake switch; 4. Faulty clutch switch; 5. Abnormal cylinder pressure leading to poor performance; 6. Leaks or blockages in the intake system; 7. ECU malfunction; 8. Occasional false alarms due to sporadic faults.
