My 07 tahoe threw a check engine light. Went to autozone and they said it was the TPS. Got a new one and about to install. My question is after I install am I going to have to take it to the dealership to get them to relearn the new sensor? I know if I were replacing the throttle body I would have to. Just don't know if I will need to with just the sensor being replaced. Thanks for any input. P.S. This is My first time posting to this forum.
