Upon puttining in a new tps I can't get the correct ohm reading at wot. Fully closed I got .8 but at wot I get 2.6. My manual is calling for 3-10 at wot. I tried to adjust the set screw but to no avail, so I took the tps back to autozone they tested it an said it was fine. Please help

Did you try measuring the resistance VTA-E2 with the TPS off the truck? If you can get the full spec resistance (3.3k-12.1k ohms), then the problem is not with the TPS, but you may have something bent in your throttle linkage.

What happened at Autozone? Did they measure the part with an ohmmeter?

 

I would check the wiring coming to the TPS to make sure it wasn't being 'slightly' shorted somewhere along the line... I'd check them for continuity and resistance. I believe you can test the voltage coming to the TPS. I believe there is a tutorial, check youtube.

 

i'd like to know how autozone was "testing" it.

 

dont go to auto zone. they only know what the computer tells em. Napa is your best bet. or toyota.
