So today I was adjusting the TPS on my Renix Cherokee and i had my multi-meter out checking how many ohms where going through the 3 prong connector. As i was doing that i went ahead and wiggled the wiring harness and i was getting readings of 70+ ohms as i was wiggling it. So obviously I have a bad ground somewhere even though i have already refreshed all the grounds. When i went to look up how to fix this i wasn't able to decipher what wire was needed in order to be refreshed, mainly because the wires are caked in dried grease and are horribly faded from years of neglect. I was wondering if anybody has any advice for finding the wire or maybe some pictures of where the wire meets the 3 other wires so i can pretty much get an idea of what to do. It's a 1987 Jeep Cherokee.

 

Here ya go.

Ok so today I wired and soldered everything up and i got readings of 0.5 ohms. just for an extra measure i wiggled the wiring harness while i had it hooked up and it stayed stable at 0.5 ohms. After that was done i proceeded to adjust the TPS and i started to get 0 volts on the output side of the connector. I tried to adjust the TPS even though it said it was at 0, but i was still getting nothing. It stayed at 0 the whole time. So now i'm going to assume that the TPS is bad and needs replacing.

 

Yup.
