Throttle position sensor troubleshooting

[Sargas3]

I got it! Ok so I tested everything working my way back to the PCM And Again I started in the wrong direction. The plug had the correct 12 volt but the pin inside had been pushed in just a little when I put it together. It was enough. I reseated all the pins. (tip using a large sowing needle to line up each pin as I pushed the plug back together) It started right up. No codes!!!! Again thank you everyone willing to get on here and give me a hand! I really apricate it!

Well. Freaking. Done man. Troubleshooting is the most rewarding part of wrenching to me. There’s nothing like using methods and techniques, and following the clues to isolate an issue. Things like “clean your grounds”, blindly ripping apart a wiring harness to check wires, or automatically sending off a PCM to be tested are common advice on here. A test light can answer almost all these questions in an instant and eliminate guess work and down time.

With the lack of quality in the aftermarket parts market, now more than ever, our TJ’s are going to require actually troubleshooting the issue. Firing the parts cannon and blindly replacing perfectly good sensors with aftermarket junk, and in turn, introducing new faults to an already existing problem can muddy the waters so bad it’ll make your head spin.

You followed the path straight to your answer. Congrats brother.

Thank you! Just got back from a drive and its running better than it ever has. And 1 crank to start now. Again that you for all the help! I hope this thread helps others as well.
