The reason for the EPC light coming on while driving and then turning off after restarting is: Dirty throttle body: The EPC light mainly illuminates due to a dirty throttle body; Solution: In this case, simply cleaning the throttle body and then performing a reset can resolve the issue. Faulty intake system: If there is a fault in the intake system, the engine will detect this fault after starting and illuminate the EPC warning light. Solution: This situation requires inspection and repair at a service station. The main reasons for the engine fault light coming on are excessive carbon deposits in the throttle body or inside the engine, and a malfunctioning oxygen sensor causing an imbalance in the air-fuel mixture, which easily triggers the engine fault light. If the fault light comes on in a new car, it is usually due to the use of lower-grade fuel.
