Default Loose wire

I have a 95 Cherokee Sport. For the life of me I can't remember, or find where this wire goes. It's one of the ones I didn't take a picture of. Any ideas? Comes out of the harness on the passenger side next to the windshield washer fluid tank.

1990 Jeep Cherokee 4.0 4x4

I power washed the engine bay mainly on the passenger side in prep for leak repairs. I avoided all major sensors also sprayed the bottom of the engine and the trans.

Ever since then the jeep will not downshift to pass, it will not exceed 2300rpm. No matter if WOT or feather the gas. However in park and nuetral I can rev the engine freely to 5000+ rpm without issue.

First gear gets to 2300rpm, 2nd goes to about 2000 then downshifts into OD and I cant floor it and have it downshift to pass or anything. It downshifts when slowing down to a stop perfectly.

What should I look into?

If I recall correctly the Renix TPSes for automagic XJs actually have two sides. One feeds throttle position to the ECU, one to the TCU. Test everything with a multimeter.

Sincr nobody finished this (or I missed this) what he meant to type was drive shafts.

OP since you have an NP242, I would replace the U joints. That transfer case does not lock anything in 4WD Full Time.

I love my jeep but this bucking, sputtering is driving me crazier than I already am...PLEASE any ADVICE is appreciated...I have researched this code and it looks to me like its a guessing game as to the problem....Thanks from a mama that stays on the go!!!
New motor with old sensors? :|

Camshaft Position Sensor sounds like a good place to start for an OBD-II 4.0L but I have no idea if you have the V8... You should try in the Grand Cherokee section as your vehicles is two model generations away from the Cherokee.

Default Missing bolt in transmission face?

Anyone know what kind/size of bolt to use for the area circled in yellow? My 91 Sport seems to be missing that bolt, and I've got a small leak from the area.

Went back to my jeep and it started. Ran all the seafoam out and it ran a little better. It stalled once on the way back but other then that good. I'll get a Mopar CPS tomorrow and install it

Might not be a bad CPS.

Like i said, test it first. Things are expensive...

Replaced mine and didn't tie back the wires. Replaced it again after they melted to the downpipe. $150 later, my CPS is fixed.
