I'm trying to find the TPS and checks its proper operation. Is it attached directly on top of the TB or below? What are the operational specs? I think mine's bad and causing other issues. Can I get a parts diagram blow-up? Thanks.

 

mine on my 03 p5 is on the right side of the TB...it's a black plastic piece with a connector going into it. There will be 3 wires. white, black and green (iirc). You'll test the green (signal wire) There should be a sweep of 0v-5v. If it's not constant or doesn't reach either voltage limit then there's a problem.

 

TPS failure is rare IMHO.

We need the year/engine of the vehicle and I can try and get that blow up.

 

TPS failure isn't rare on my rx7!! hahaha, that thing sucks!

 

That's a whole different critter.

 

Yeah... I checked it out yesterday on the multimeter. It seemed okay: 2.0L 2001. Resistance between two of the three connections (not signal wire) was 1150 to 4590 Ohms from closed throttle to WOT. Not sure if within specs but definately working. I was ruling it out as part of my ATX troubleshooting procedure. [see thread in general area.]
