What does engine EPC mean?
1 Answers
EPC stands for the Engine Electronic Stability System. Generally, there are two possible reasons for the EPC light to illuminate. One is a dirty throttle body, which should be cleaned. The other is malfunctioning brake lights, requiring inspection of the brake switch and wiring. Additionally, poor fuel quality can also trigger the EPC warning light. Solutions for an illuminated EPC light include: 1. Troubleshooting the intake system, using compliant fuel, and cleaning the throttle body. 2. Removing carbon deposits and performing cleaning in relevant areas. 3. Reflashing ECU-related data (this applies when other issues are resolved but the problem persists). 4. Other faults cannot be ruled out, so specific repairs should be based on actual vehicle diagnostic results.
