What does it mean when both the EPC light and engine light are on?
1 Answers
When both the EPC light and engine malfunction light illuminate, it may indicate a fault in the engine power electronic regulation system, requiring immediate engine inspection. Common causes include a dirty throttle body, vacuum leaks in the intake system, a faulty brake switch, or delayed engine updates. Below is relevant information about the EPC light: 1. Introduction: EPC stands for Electronic Power Control (electronic throttle). The EPC light warns of common faults in the electronic throttle system. If this light stays on, it suggests a potential issue within the system that may affect normal vehicle operation. 2. Self-check method for EPC light: A continuously illuminated EPC indicator signifies a fault in the engine or electronic systems. During startup, the EPC light will briefly illuminate for a few seconds as part of the vehicle's self-check and then turn off. If the light remains on or flashes after ignition or while driving, it indicates that the management system has detected an engine or electronic system fault, and professional inspection should be sought immediately.
