It's an electronically-controlled gas pedal. One of the most important things it does is keep you from doing burnouts down the street--it monitors the wheels and, if they break loose, backs you out of the gas until they hook up again. This way you don't tear stuff up.
Electronic Pedal Control
Electronic Pedal Control (EPC) is Volkswagen's electronic-accelerator-pedal system.
Means Electronic Pedal Control--fly-by-wire for the gas pedal.
electronic pedal or power control
EPC stands for Electronic Power Control
EPC means Electronic Pedal Control. Fly-by-wire for your gas pedal--instead of a mechanical cable that pulls an accelerator linkage on the engine, there's an electronic device on the gas pedal, an electronic device on the throttle body and a wire between them.
EPC means Electronic Pedal Control. Volkswagen uses an electronic system, not just a cable running from the gas pedal to the throttle, to control engine speed. It would make implementing cruise control REAL easy, if nothing else. If you have an EPC light on...that's the car's Check Engine light.
You can get a 1960 VW gas pedal diagram from most auto parts stores. The diagram can be found in a VW repair manual.
The epc alarm on a VW Jetta is the electronic power control. When this light comes on it is to warn you of some sort of problem with the accelerator pedal control. This can come on because there is a serious problem or just because of a bad sensor, the best thing to do is to have a diagnostic test done to make sure there is nothing seriously wrong.
The EPC (Electronic Pedal Control) is the "fly by wire" system that controls the throttle, it took the place of the cable that went from the gas pedal to the throttle body on VW. If this light is on and there is also a P0102, MAF (Mass Air Flow) related code stored in the vehicle's computer, the EPC may be caused indirectly from a faulty MAF. If the EPC is on and there is no other codes stored, it could be a faulty electronic throttle body or need to be re-programmed. The vehicle's computer must recognoze the throttle body so when replacing it with new or used it will need to be programmed at the dealer. Recently I replaced a MAF (a common problem on VW's) on a VW Golf and when I cleared the code the EPC went off as well.
