What are the odds?

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?

Guess the tide is turning. Let it set for two days. Started it up. CEL went out. Cleared codes and drove it. All good now.
