dbw problems. tps %is 20 at idle.
 

My friend has a 07 tahoe. And he said one day he was booking it. And after that the transmission dosnt want want to shift it was idle problems. And I hooked up my hptuner and scanned it. And at idle is 20 percent tps. And if I push it all the way and Its says 89 percent. So I'm thinking its the pedal. That can be it no? Where is the tps connected at the throttle body or the pedal? and I have an 04 1500 chevy can the pedal module from that fit it or are they differant?

the tps has a 5v refrence if ur at 89% i would say thats about 4.79V or sumwhere around there and that sounds close to normal i dont think thats ur problem you can hook it up to tech II tho and reset the tps...is there sum big hyphy wheels on it? sumtimes that can fuck things up

Hook it back up to the scanner and see what the TPS reads when you manually open it WOT. Not sure if that works on an elec controlled TB though (if equipped).

Lol yea its on 26s and airbags. Where can I get a hold of a tech 2? Or can I just reset the pcm? And how is that done?

you can get ahold of a tech 2 with a couple g haha

wait for GM to start having yard sales at the dealer lots that are closing LOL
