Reduced Engine Power - limted to 11mph

[BobX]

Thanks for all of the help, guys. How do I check the codes on DME, Paul? Is that different from engine trouble codes? I've had the battery charged and still not getting any success. I still do not hear the throttle body motor. Does it matter if I have the hood up or have the battery charger hooked up? Does the boxster have a hood switch?

Where are you located?

[Paul]

The DME is one of several computers that can post codes.



Here's some eGas codes:

Thanks Paul. I live in Ann Arbor, MI. These are p codes so they should illuminate the check engine light, no? Do you think my pedal sensor has failed? what does egas learn do? learn the minimum position?

[Paul]

As you can see from the displays:

Lamp off



Any time the battery is disconnected, the eGAS off throttle settings must be relearned.

Well, the check engine light finally came on. I still cannot "learn the egas". I even tried disconnecting battery just to see if I can get it to learn. No success. I'm going to try to pull codes next. Is there a history of sensor failure in these cars? I did try to crank the engine with a low battery, but I can't imagine that failing accelerator pedal sensors. Anyone know what else I can try before taking it in?

Status please.
