My epc light went on in my 2002 volkswagen jetta

the glove box users guide lost?
it tells what to do for EPC>
sure get the car serviced is the answer.
Electronic Power Control warning light, is an indicator pointing to issues with your Volkswagen's throttle system. This could mean that the throttle pedal, throttle body, traction control, or cruise control unit need attention.

it means get it service,
or if DIY, not told that.
we scan the PCM .
it then tells my which end is failing, TB or right foot throttle. pots.

EPC, when glows, the cars power is restricted to 20 mph on most carfs
or if bad engine, the car can;'t drive at all.

Toyota was sued for 1billion bucks with a B. and now all car makers are
really scared. they be next and like magic, TWB throttle by wire is now on all cars. made. no more throttle cables to rust and jam and mom runs over kids.
it is SOLVED.
get it serviced
or get it scanned or you scan it.
your choices
and answered here over 1000 times and 1million times googled.
TBW loves top fail.
gee it lasted 19 years,.
even a simple dirty TB, throttle body now cleaned can fixed, it.

first google hit,(overkill to the max ) 2 things can be wrong. scan it and fix it.

EPC light should have nothing to do with the shift interlock,(EPC is traction control) should be a small cap or plug on the console, near the shifter that has the interlock disengage button,usually done with a key,check shift interlock in the owners manual.

You may have blow the fuses check all of them.

you need to change your

Crankshaft Sensor that will fix you problem !!

try unplugging the battery and replugging it and then starting the car. hope that helps

GO TO AUTOZONE OR ADVANCE HAVE THEM PULL CODES USUALLY FOR FREE DEALER CHARGES 99 THEN POST CODES I CAN HELP

need to recalibrate the throttlebody

Call dealerto replace brake light switch, some of them were covered under warranty. They were **** and they replaced all of them.

sounds like you need to reset readiness ,which resets throttle and several other things. unfortunatly it needs to be done with vagcom or vcds software, so back to dealer or a reputable VW repair shop
