TPS issues and P0123 code

[jpdido2]

Just got back from a long wheeling trip up at Windrock. Drove the Jeep there wheeled 5 days and drove back. The next day I go and start the Jeep and it’s idling really high 1500 rpm and the check engine light comes on. So I go get a scanner and throw it on there P1294 and P0505. So I get a new IAC valve and put it on. Clear the codes start up the Jeep and the. It throws a P0123. Go to the parts store grab a new TPS non mopar, I know bad idea, because it didn’t work same thing. So I order up one from mopar. Get it installed and it’s still throwing the same code. Any suggestions? Does the TPS need to be adjusted? Did I get a bad one from Mopar?

Check a few things that don't cost you anything...
Check the (3) 32 pin harness connector pins and clips for the ECM for oxidation and ensure they are snapped firmly into the ECM receptacles.
Then check the harness that wraps around the back of the valve cover on the drivers side where is comes in contact with a head stud; the stud has a tendency to rub thru the wiring insulation and bare wiring can occasionally short to ground.

I am completely out of ideas I have checked the wiring the connector I replace the connector I’ve gone through everything that I can think of check for vacuum leaks everything. I replaced the throttle positioning sensor twice both times Mopar factory parts still throwing P0123 code

There’s no shame in taking it to a mechanic if you truly have exhausted ideas.

After reading threads on other forums. I checked a few things and found out I have a bad clockspring. I didn’t even know what that was but definitely what’s been throwing fits in my Jeep

Damn, thanks for the update! At easy it’s an easy fix.

Interesting that the Clock Spring can cause those symptoms....
Hope the problem remains solved...
