Hmmmmmm...... damn. Somehow the TB and pedal aren't talking, which could in turn lead to a dangerous situation. You'd hate for it to goof up at WOT. I'd definitely take it to the dealer and let them do what they need to do. I'm sure it's a learning thing that may need to be done with a StarScan. Bite the bullet and let them figure it out. I hate drive by wire. It can be such bullshit sometimes.

did you ever try to replace the throttle position sensor?

did you check to see if the wiring to the TPS are damaged?

try doing a TPS sweep with a volt meter.

no, the sensor right behind the pedal is the pedal position sensor.

the throttle position sensor is on the throttle body. since these are drive by wire, and what controls the actual throttle is a motor, it's most likely built within the motor. probably pretty pricey (if it is in fact that)

but harrison could be right. could just be something stupid like a re-learn.

Check all connections to the PCM and swap batteries while its disconnected.
I agree with Mike.
