Default My TPS resistance

Is 1.3 kOhms closed and 4.55 kOhms WOT. Is that normal? I was wondering if not quite reaching 4.7 was a problem.

How would I check the voltage? My multimeter has the typical point style probes.

Harpoon the wire with a pin (needle) making sure it does not touch ground, measure the voltage of the pin to ground.

Not sure of the resistance though sorry

Got .49v to 4.22v. I'd like 4.5, but does 4.22 sound okay? The FSM says you need above 4v.

Are you getting any driveability issues or check engine light on?

I found the best way to test the sensors is with a paperclip that I insert into the sensor connector from the back. Typically the TPS should be reading .38V to .44V at idle. I always set mine at .4 volts. You should be looking for 4.5 volts at WOT. Make sure that you have a good 5V reference signal and a good ground going into the sensor. Measuring the resistance is not the way we measure the TPS unless you are looking for a flat spot which could be detected via resistance. Hope this helps

I don't think I have any problems related to the TPS, I'm just getting a little happy with the multimeter.

My current problems are:
PCM trying to dump boost
Heatsoak

I don't think any of those are TPS related, unless the PCM thinks my boost is too much for just under WOT.
