1 Answers
Introduction to the situation when the EPC light on the car dashboard is on: 1. Intake system failure, such as leaks or blockages; 2. Dirty throttle body with excessive carbon deposits; 3. Use of substandard fuel; 4. Abnormal cylinder pressure and poor working conditions; 5. Valve failure, sticking or carbon deposits, etc.; 6. ECU failure; 7. Sporadic failure, false alarm. When the EPC indicator light is on, there are several solutions: 1. Troubleshoot the intake system, use qualified fuel, and clean the throttle body; 2. Remove carbon deposits from related parts; 3. Rewrite relevant ECU data. When the EPC indicator light is found to be on, the owner can first try to turn off and restart the engine to see if the EPC light is still on. If it is not on, it means there is no problem, and it is just a false alarm caused by the EPC light being affected; if the EPC light is still on or frequently lights up, then the owner should adopt the aforementioned solutions.
