07 Hummer H2 no throttle control

This is basicley a Chevy 2500 w/ LQ4.

I just backed the H2 up a little I think it was idel throttle to back up just after putting in gear an letting off brake.

Throttle was working fine a few weeks ago.Now I don’t have throttle
edit I don't drive this vehical much so I dissconnect the battery usaley I dissconnect the positive but this time I dissconnected the negative.

doe's this sound like I need to relearn the throttle position sensor?if yes a video or the procedure would be a big help
please advise

3 things happen on the throttle bodys for them GMT800 line
Either a mouse has chewed the wiring near the TB
The TB has gone bad (infrequent, but does happen)
A mouse has chewed a wire set for the canbus. I have seen everything from the fuel pump control module, air ride control module, and a few others, cause this.

Diagnostics would be required to narrow it down.
Obviously, the easiest to just change out would be the throttle body, but it may not fix the problem, or it may fix it, or it may fix it for a week or 2, and then the problem may come back

I guess it's time to order the OBD2 code reader that Mooseman recomended.

I wouldn't be a bite surprised if a mouse chewed a wire but have read they only chew wires that have a battery connected they like the little shock they get off on it.however I place moth cakes inside engine compartment in both these stored vehicals H2 & the express.

you know we'v had a familey of feral cats move in under the H2 image.
momma an 3 babies maybe there eating mice? I hope there's not a mouse infestation in backyard. I do have posumes an I catch an relocate them they can be disstructive.

will method 2 &3 possiably resolve the no throttle no mention of vehical type.

thanks

maybe this el cheapo scanner would be better?

also can just dissconnect the computer an reconnect in hopes of cleaning off the connections? sorry to be such a newb I don't even know where the computer is mounted on the hummer.

maybe also dissconnect an reconnect the throttle bodys harness also maybe spray w/ electronic cleaner on both plugs
thanks for advise
