Cleaning TPS on DBW?
Alright guys I'm driving home and CEL comes on so I stopped at parts store. I didn't get the code but they said TPS needed cleaned/replaced. Truck is '07 Tahoe with dbw throttle body. Is it gonna hurt anything to take servo unit off and clean it? If I need to replace do I need to replace whole unit? Truck idles and runs normal. I'm confused.

There is a recall on the NNBS TPS sensors bieng faulty . But I believe the recall only covers 08 up vehicles , which sucks . But if yours isn't covered go buy a new one , they aren't very expensive. What happens is condensation gets inside the TPS and damages the two gears inside , they mesh together , but the condensation makes one or both slip and get out of index with each other giving bad info to the PCM. I had mine replaced on my Denali.
