I am getting a check engine light with code P1502 showing with "no dtc definition found.
This seems to be the theft deterent fuel enable code or something. Car started and idled fine but would not respond to throttle input. Then shut off and restarted and would respond. Drove car to parts store and had code read and that is what is said. Still boosted and would kick down (tip) so not in limp mode. Any ideas? Could it be battery in key fob? car does lock and unlock with fob.

 

Porsche OBDII manual P1502 mention a problem with your throttle. Was there anything done to the throttle lately or a reprogramming of the ecu?

 

no nothing with throttle or ecu done recently. Could it be a wheel speed sensor? I have heard several things could cause p1502 but not sure why throttle would have not responded that one time.

 

Not familiar with this relation... You did not disconnect the battery lately? If you did try the throttle adaptation mention in the OBDII manual (copy posted previously)

 

brake pedal switch?
