Must be you have one of the ones with slots instead of holes for the screws, eh?

Well, I do recall someone on here posting the suggested voltage range for a TPS sensor, at idle and WOT. Let me see...

Looks like about .5 v at idle, and 4.5 at WOT should be fine. I didn't find actual suggested numbers, but that is a reading from a good running car. Just adjust the sensor until you get readings somewhat close to those. If memory serves me, there are three wires going into that sensor, 5v in, variable voltage out, and ground. Just probe the ground and variable voltage with a multimeter to get your readings. I don't know which is which, just probe until you find the right combination.

Even if you have it adjusted right, it might still be off from what your old sensor was reading. It might take a while for your ECM to re-learn that.

Well, keep in mind that you need to do this with the wire harness connected, because the sensor requires input voltage to give an output voltage.

I can't say off hand what wire is which, but I think one might be pink/black, which would be your input voltage. Don't probe that one. Probe the other two. Doesn't matter which probe to which wire. Just ignore the - in front of your reading, if you get it backwards.

Alternately, you can just probe one of the wires, and touch the other lead to a body or engine ground. But then you have to figure out which wire is the output/signal wire. Trial and error worked for me, but maybe someone else will know and post which wire is which.
