Default TP sensor failure


I tried to replace the TP sensor several time, but failed everytime. I can't really take out the old TP sensor from the engine. Mounting bolts looks like 1/4 inch fits on it, but it doesn't work.

I asked the mechanic, but he doesn't know. Even he said, I better take out the cooland in-take hose to replace the TP sensor.

Anybody has ever done this job before? Please let me know what size of wrench should I use, or any other things I have to remember before I mess this.

It'* alot easier if you remove the throttle body entirely. The SE/SSE non-supercharged models are a little more difficult, as you have a TOUGH nut to get to underneath the TB itself. You must remove the crossover pipe heatshield to remove the throttle bracket, then only 3 nuts on the TB studs.

You'll hate yourself if you keep fighting to do it with the TB installed in the car.
