What is the issue when the EPC light is on in a Chery A1?
2 Answers
Chery A1 EPC light is on due to a dirty throttle body or an air intake system leak. Here is the relevant information: Dirty throttle body: If the throttle body is dirty, simply cleaning it and then performing a reset can resolve the issue. Air intake system leak: An air intake system leak causes the engine control unit to detect the problem and illuminate the EPC warning light. Severe or obvious vacuum leaks are not the issue; only minor leaks that the control unit cannot effectively detect. When the compensation adjustments made by the control unit exceed the limits allowed by its internal program, the control unit will determine that there is a problem with the electronic throttle system, and the EPC fault light will turn on.
I've been driving a Chery A1 for several years. The last time the EPC light came on, it was due to an issue with the electronic throttle control system. Common causes include a faulty throttle pedal sensor or signal errors caused by a dirty throttle body. It could also be due to a blown fuse, poor wiring contact, or the ECU unit detecting an abnormality. If the light comes on while driving and you notice sluggish throttle response or weak acceleration, don't push it—pull over promptly. Try restarting the vehicle to see if the light goes off. If it doesn't, head to a professional repair shop for inspection, otherwise the car might not start after stalling. My experience shows that regular throttle cleaning can prevent such issues.
