What are the reasons for the EPC light being on and insufficient power?
1 Answers
EPC light being on and insufficient power may be caused by the following two reasons: 1. Engine management system or electronic control failure: Often accompanied by unstable idling or cold start engine shaking, usually caused by poor fuel quality and dirty driving environment. It is necessary to drive to a maintenance service station as soon as possible for inspection and cleaning of the throttle. 2. Engine power electronic control system failure: Dirty throttle valve body, vacuum leakage in the intake system, damaged brake switch, or untimely engine upgrade may all cause EPC faults. The engine must be checked immediately.
