What are the reasons for the EPC light coming on and the car shaking?
1 Answers
epc light coming on and the car shaking are caused by: 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; 6. ECU failure; 7. Sporadic faults or false alarms. The EPC corresponds to the electronic throttle, which is an important control component of the car engine, ensuring precise control of the throttle opening. If any of the above reasons occur, the electronic throttle cannot accurately adjust the throttle opening, leading to a decrease in engine power and resulting in car shaking.
