I just realized today that my TPS is bad not my KS! WOOO! Just saved my self a lot of money and the hassle of trying to replace a knock sensor. So you guys that think you have a bad knocksensor should make sure that is exactly whats wrong. Has anyone ever changed there TPS? Is it hard?

 

It has 2 bolts and 1 clip plus its on the throttle body. Should take less than 1 hour to replace.

 

How did you figure out your TPS was bad? I've been trying to do the test based on the Haynes manual but am not excatly sure if TPS is bad or not. FYI the 2 screws are small and hard to remove, if you can't remove it initial spray some liquid wrench, and let it sit overnight.
It work for me.

 

I got the CEL code0403

 

if u wanna know if its bad or not take it out and take it to autozone, they will test alot of **** for free. i know because i work there. and gawdaym a KS for a maxima is 250 buks

 

It's easier with the TB off the car to get the TPS off. Just a warning, those screws are on very tight. Normal screwdriver won't able to break them loose. You will need an impact screwdriver. I could take some pictures if you want. I have a spare TB.
