Do you have throttle cables or drive by wire? If you have the cable less system then your TPS is built into the throttle unit. That is why you can not find one.

it is all wire that would explain a lot. so if there was something wrong id have to change whole unit. is there any way to check this

Not without special tools and procedures. We try not mess with them an any cars at my shop, we send them to the dealer. On that note I have never seen a problem with one on a GM. I only have seen problems on Volvo and Nissan.
