IT WAS A TEMP SENSOR ON THE SIDE OF THE BLOCK, NOT THE ONE FOR THE GAUGE $15.99 FOR 1YR OF CHASING AND CHANGING HIGH DOLLAR PARTS TO FIND THIS LITTLE JEWELL IT ALSO FIXED THE NO POWER & SHIFTING ISSUES I HAD COME TO FIND OUT IT GIVES THE COMPUTER INFO. AND IT CHANGES TIMING WHICH CHANGES SHIFT PATTERNS[/quote]
What year was yours again?
I think I still hold the record for taking the longest to find the temperature sensor on jeep, like 18 months. Mine is an 87 Renix, and they hid it up under the intake/exhaust manifolds then. Never new it was there, and it wasn't even connected (which is why I never found it before). Then of course Renix has 3 of the bloody temperature sensors, and I knew where two where so I never bothered looking for a third one.:dunno: By 97 (I think) Chrysler discovered they could use just one Temperature sensor and save money, LOL.:clap:
But once I found it, I tested it, and it was OK, then I reconnected it and I still had no power and no down shift on the AW4. Mine turned out to be a bad TPS causing the poor power shifting and poor engine power problems.
Interesting that the same symptoms can be caused by such different parts.
I am now wondering if the power problem with mine was extra difficult to solve since it was being caused by more than one thing? By the time I got the 87 XJ, almost everything on it (except the engine, tranny and drive train) was on its last legs, the cap, rotor, wires, distributor, CPS, TPS, IAC, IATS, 6 new non-leaking injectors, just to start with all died in less than 12 months. They were either the original parts (18 years old at the time) or past their end of life, Junk yard pulls that should have been left there. It would now be easier to list the parts I have not replaced on my 87 XJ. The good news for me is there is very little left on it that is not new, that can wear out any time soon.
