Hello Loren, thanks for all your suggestions. I did finally fix the boxster. I found the wiring schematics for the dme and with your first suggestion of a short circuit of the wiring harness. I decided to work on the throttle body wiring to the dme. I initially thought something was wrong w the dme as it was not sending the signal that i needed but upon further investigation and the intake connections removal i found the issue. Rats had chewed into the harness at two locations under the intake manifold. I had the throttle problem and oil level sensor problem and both were attributed to chewed up wires. I was able to repair the harness and i performed the throttle adaptation. The engine started right up and problem fixed. Thanks for your input. Much appreciated.

Loren thanks for your response. I dont feel like its the throttle body as i have tried 3 separate throttle bodies and all three are clean. The check engine code for P1503 can not be erased and immediately comes on before the engine even starts up. I will try to examine the wiring harness from the throttle body to the dme and hope to find something. Any help or insight you give me is much appreciated. Would you happen to know the wiring schematics from throttle body to dme?

Sorry for bringing this issue up from the past but any help would be greatly appreciated. I have a 2002 boxster 986 w the e throttle also. I have very similar issues as above. I have replaced the throttle body assembly and the accelerator pedal potentiometer at the pedal assembly. Both with now resolve. My code is P1503 DVE fault position deviation which i believe is also the throttle body. Your post is the only one which says replace the DME resolved the issue. May I ask how you replaced the DME? Does it have to be new (from dealer and programmed to vehicle) or used is ok? And if used do I have to get the immobilizer also? How did you do it is what im asking.
