You’re driving your car and the EPC light suddenly appears on the dashboard. What does it mean? What is the cause? How can you fix it? There are many questions about the EPC warning light because it’s a common cause for concern, as it usually means that there is an issue with the car. EPC What Is The EPC Light? The Electronic Power Control system is monitored by the engine-, brake-, transmission- and steering control units. The Electronic Power Control (EPC) warning light indicates a problem with your throttle system; which includes the throttle body, accelerator pedal, cruise control and/or traction control.  The EPC light generally shows up with the Engine-, ABS- or ESP light, depending on where the problem is coming from.   Common EPC Light Causes When the EPC warning light is on, your cars’ performance is limited. The most common causes of the EPC light showing are a faulty throttle body, faulty brake pedal switch, faulty ABS sensor or a cracked ABS ring. Here are a few more issues that could trigger the EPC light:
  • Throttle body failure
  • Bad/faulty ABS sensor
  • Failed brake pedal switch
  • Cracked/faulty ABS ring
  • Faulty brake pressure sensor
  • Faulty engine sensor
  • Internal engine problems
  • Power steering failure
  • Faulty steering wheel sensor
  • Wiring issues
  Can You Drive With An On EPC Light? You should always have the EPC light checked out as soon as possible. When this light goes on it means there could be a few issues/faults in your vehicle. Because the EPC is integrated with the steering and brake system, it could cause engine damage and accidents because of limited brake or steering functions.
