Re: Throttle position sensor
Apparently they're not supposed to be serviceable, everything I found says just to replace the whole throttle body (ouch.)
Just found a TSB about that DTC:

Re: Throttle position sensor
Had a check engine light problem last winter and it was the tps... the whole throttle body was replaced.
Re: Throttle position sensor
dang....thanks for the info guys
bad part tho is that ive taken my throttle body off and ive driven my car through water, i know that the dealer will be able to tell ive taken it off becasue they use markings to determine it so they probably wont cover it under the tsb. plus, i dont like hassling with dealers so im gonna order the part myself and replace it.
