2009 Chevrolet Silverado 1500 6.0L mil lamp on hesitation

Truck problem:

This truck goes on limped mode while being driven on the road and won't past 35 km per hour. Check for codes and it has a code:

p0325- Tps 1 and 2 correlation

Looking at the dash panel, the traction control light and the stability control lights are on when the transmission were on limped mode. We did all the basic checks like servicing the throttle body and reflashed the ecm using Tech 2 scanner. Also replaced the APP or throttle pedal but the problem is still there. We are not at a loss on how to proceed.

ATS Adviser:

You need a new throttle position kit for this code and this is free from GM as per their bulletin #11273 B and the recommended part number is 19259452 which is under warranty for 10 years. I am sure they will give it to you if you give them a call.

FINAL FIX:

The GM dealer near our shop performed the warranty repair as a warranty job under 10 years or 120,000 miles coverage. Thanks!
