I've got a 2011 with about 200k miles. 5 LLY, 2X, shell, XDR, MikeL Heavy duty up-grade, 6spd, TransGo, deep pan, de-badged, 65 Gallon replacement Aero tank, LBZ-mp, Kennedy …. Happened when we were at a rest area halfway up GA. Is it just a buy the throttle pedal assembly and go or is this not a common problem, my dealer makes it sound like thats what it is and it's not going to be covered under warranty. So i figured I'll chance it and take it back to the dealer. Although of you have a cel with NOX codes (usually p0023e) sensor replacement will turn out the light. The ECM will use this value until the enable criteria have been met. And that combined with values of 50-100ppm for sensor 1 and 65535 for sensor 2, it makes sense to assume that sensor 2 is either faulty or connected badly. Replacing the turbo may take 8 to 10 hours and cost around $2500. Unscrew the sensor, soak it in brake cleaner first until the plunger moves in/out easily by hand, dry off with compressed air, soak the end in WD40 then reinstall and see if it helps. In this article, we will discuss one commonly found code, P2BAD - NOx Exceedence - Root Cause Unknown. We added more def and - Answered by a verified GMC Mechanic. I think I have it narrowed down to possibly bad thermostats allowing coolant to flow.
