1 Answers
EPC stands for Electronic Power Control system, also known as the electronic throttle. Below are the methods to resolve the EPC light in a car: 1. Troubleshoot the intake system, use fuel that meets standards, and clean the throttle body. 2. Remove carbon deposits from related components and perform cleaning. 3. Reflash the ECU data (use this method if the issue persists after resolving other faults). 4. Do not rule out the possibility of other faults; proceed with repairs based on actual vehicle diagnostic results. The EPC light in a car may appear due to the following reasons: 1. Intake system faults, such as leaks or blockages. 2. Dirty throttle body, excessive carbon deposits, or use of substandard fuel. 3. Abnormal cylinder pressure or poor engine performance. 4. Sporadic faults or false alarms. 5. Valve faults, such as sticking or carbon deposits, or ECU malfunctions.
