What is the problem when the EPC light of Refine is on?
2 Answers
When the EPC light of Refine is on, it may indicate the following two issues: 1. Dirty throttle valve, which should be cleaned. 2. Brake light not working, requiring bulb replacement or inspection of the brake switch and wiring. Here are some relevant details: 1. A constantly illuminated EPC warning light indicates a fault in the engine management system or electronic control, often accompanied by unstable idling or cold start engine vibrations. For domestic car owners, this is usually caused by the quality of fuel and dirty driving conditions. It is recommended to drive to a service station as soon as possible for inspection, and cleaning the throttle valve can resolve the issue. 2. The EPC indicator light will illuminate when the ignition is turned on for a function check. If this light comes on while driving, it indicates a fault in the engine power electronic control system. The engine must be checked immediately.
A few days ago, the EPC light in my JAC Refine came on, which was really unsettling. As a long-time owner, I've experienced similar issues several times. The EPC light indicates an Electronic Power Control system fault, which could mean a faulty throttle position sensor or loose wiring connection. I checked the battery terminals myself and found them slightly loose - tightening them made the light go off. But sometimes the sensor is genuinely damaged, requiring a visit to the repair shop for diagnostic computer scanning. When the light is on, the car may experience sluggish acceleration, seriously affecting driving safety. I suggest not delaying - either perform simple self-checks or seek professional help immediately. Regular throttle maintenance like cleaning every 20,000 km can prevent this issue.
