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?

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?

P1502 Pending
Finally got a code reader hooked up and saw a P1502 Pending. When I clear codes while the vehicle is running, the car runs like there is nothing wrong. Reading codes after clear codes, there are no faults active or pending. But on the following start, it will go back into reduced power mode and have P1502 Pending. Based on what I've learned so far, it won't learn "egas" and it is failing some throttle code during key up. However, I think it's failing falsely as once the code is cleared, the vehicle runs flawlessly. Not really sure what to do at this point. And thanks for the followup, Paul.
Any help would be appreciated.
Robert
