The OBD shows codes PO113 & PO123. It won't shift into overdrive and the cruise won't work. Also missing out
Trouble Code: P0113
IAT Sensor Circuit High Input
Possible Causes:
IAT Sensor signal circuit shorted to VREF (5v)
IAT Sensor signal circuit is open, or the ground circuit is open
Trouble Code: P0123
TP Sensor/APPS Circuit High Input
Possible Causes:
Related TP Sensor engine DTCs present
Intermittent wiring or connector problem
TP signal circuit is open or is shorted to battery voltage or to 5v supply circuit
TP sensor has failed
TP sensor ground circuit is open
PCM has failed IAT Sensor is damaged or it has failed (an internal open circuit)
PCM has failed
SOURCE: I have a 1999 jeep grand Cherokee larado V6.
The P1391 code indicates that the crank or cam sensor(s) have sent an intermitant code to the ecm. The most common cause for this is loose wiring or debris on the contacts of one of the sensors.
SOURCE: 94 jeep grand cherokee will not shift into overdrive
chk. and see if fuse is ok. fuse box in car and under hood
SOURCE: 2000 jeep grand cherokee limited starts in 3rd gear
oil pressure problem should be checked independently of other problems...Use a good accurate mechanical gauge to check. If pressure is good (no less than 15psi at idle hot (I prefer to see at least 20) check dash grounding, block ground and if OK, change sending unit. Dash and body ground can influence operation of shift and body control modules so indirectly your problem may or may not be related, depending upon what you find while testing. And it could turn out to be a defective module! They are expensive and just plugging new ones in may work, but then again, it might not. I might be totally incorrect on this...that's the value of actually being there instead of doing this by "remote control".
If you read the numerous posts pertaining to all vehicles, you will see that you are not alone with electrical problems...As long as the engineers who design this stuff, keep using "modules" to replace ordinary simple and reliable systems, we will continue to have these problems. Do some testing and I'm sure you will find a solution! (I'm still waiting for someone to make a program for a PC that will give a complete readout of every system in a vehicle, including exact faults instead of general system "suggestions")
Good luck
