The TPS is mounted to the side of the throttle body.
Hello, do you have a black box attatched to your throttle body?
Ok so sounds like you have an electronic throttle body(no cables attached)? Are you setting codes(check engine light)? what codes?
Yes it setting codes:
Ok sorry asking so many questions, I just don't want to lead you in the wrong direction.
There are actually 2 throttle position sensors built integral(not servicable) to the throttle body, this mean the only way to replace the sensors is to replace the throttle body. However I have been able to clean the throttle body and that has fixed a couple. What happens on an older or higher milage vehicle the throttle body gets coked(carboned up) and it gets very sticky when warm, to sticky for the throttle actuator to open the throttle plate. So my advice would be to clean the throttle body. Cleaning it will repair this issue about 80%, 20% of the time you need to replace the throttle body.
