My mechanic (with 30 years of German car experience) can not figure out what's going on. The truck kept going into failsafe mode but would still drive. He thought the gas pedal was bad so he put a new one in and same problem.

He has Autologic tools and has been working with them on the issue. Here are the faults:

230-E6 Pedal travel sensor, signal
231-E7 " " " , potentiometer 1, signal
232-E8 " " " , " 2, "
229-E5 Comparison, supplies, pedal-travel sensor

Also, when it's hooked up to the reader, and just the key is turned to first position (engine not running), it says the truck is at 920 RPMs.

He says something is all balled up in the brain. It's been a real PITA!

Any clues on this??

Thanks!
