Getting weirder.
2004 Yukon XL Denali. Everything was working as it should. Battery died. Installed new battery. Immediately, I got CEL and a message that stabiltrac was turned off. Scanned and got codes P0120 (TPS circuit a) and P2135 (TPS circuit b).
Cleared codes but they came back. Don't see how I could have disturbed wiring at throttle body, but checked anyway. All connections are clean as can be.
Anyone run into this before?
