EPC= electronic pedal control it is a sensor and is located in front of the brake pedal . Depress brake with one hand ,the sensor with the other and release fast. this should disengauge the EPC lock listen for a thunk made by the EPC lock disengaging.

Go to auto zone. They will use a code reader to help you find exact component or components having errors. If its not the EPC.
it sounds like your mass air sensor or the throttle control sensor may be bad. Your gas and air may not be mixing properly thus causing your car to sputter, hesitate, and idle rough. It could be some other thinks like a bad plug or wire etc. Good Luck hope this helps. Please rate me if this helps thank you.

2000 ford escort 2.0L. plugs, wires, coil pack, alternator, MAF sensor. hard to start and RPM around 1k wants to die (any stops) always runs rough. Says air intake sensor. catalytic converter or CCRM?


Have you cleaned the throttle body and throttle body valve? have you cleaned the idle speed control air bypass valve? are the injectors clean? Are there any fault codes in memory, do the things I mentioned if you haven't already. Also hard engine mounts can cause roughness at idle. Another thing is the timing belt tight?

Most likely if you have the model that is drive by wire aka electronic throttle body the 9 times out of 10 your gas peddle is on it last legs replacing it will most likely solve your issue with epc light comming on

When i turn the AC in my audi a4 the RPM start to playing from 500 rpm to 1000 rpm why


Typically these things happen because the throttle body is dirty and the computer is searching for the propper setting with the idle speed control motor. May also be a vacuum leak .Check all of your small vac. hoses and clean throttle body and that should fix ya. Good Luick.

High rpm's and not going fast


the very 1st thing u do is have the system tested for the trouble code that is stored whenever the check eng light comes on, but most likely u need a transmission speed sensor, u have lost Over Drive by the sound of it.

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.

Check the engine codes, and replace or repair the faulty sensor (most likely the MAF sensor).

Thanks for using FixYa - a FixYa rating is appreciated!!
