I just got my car back today from the dealer. I had a problem with my TPS. Well i got home and looked at the paper explaining everything it said reprogrammed keys and pcm per DTC DIAG. P0633. I know that codes comes up when you have stage 1. Also it didn't even say anything about the P0122 code. My question is: Is there anyway that they could have reprogrammed my computer back to stage 0? I don't know if thats a dumb question or not but would they no the difference between stage 0 and 1 when they do that?

 

they probably didn't know it was a stage 1 ecu. no, they can't turn it back to a stage 0. they actually probably didn't do anything. if they did manage to get rid of the 633 code for you then that's a good thing.

 

Another question where is the TPS located at exactly?

 

On the throttle body, whick is bolted to the intake manifold
