2000 Jeep Grand Cherokee Laredo PO123

4.7L jeep
the p07 code is tranny error.
cutting off all power means , power to rear wheels or DC battery power to some things ,electrical things die?)
on all cars, DC power must be good first or the computers fail or go mad.
P0455 is gas cap loose, ignore it until all else is cured.
unless cap is missing sure.
Shift Solenoid "D" Malfunction. 0755

fix DC power distribution problems first.
bad grounds, bad connectors, alternator weak or dead
fuses blown or loose
loose wire lugs, or connectors.
rusty ground lugs wires.

title ,DIES Driving.
so dies means engine stalls. not tranny slip right.?
if is stalling can you save the stall before it completes the stall
by fast right foot actions
when it stalls tell the helper all other electrical things that die at the event. Radio dead, head lamps and parking lamps dead.
heater or AC cool blower dead?

Seems to me a pure electrical failure so far.

use a real scan tool
only that works.
you need to see all jeep DTC error.s

It is most likely the TPS sensor for the P0123 code(TPS voltage out of range). If P0123 occurs again, repair. The P0162 may be a result of the P0123 failure. So repairing the P0123 may also correct the P0162 fault.


The P0162 appears to be Jeep enginr specific. The following link may be of help.

P0162 DTC For Mitsubishi Jeep

P0123 is a TPS/Pedal Position Sensor A Circuit High Input code. P0162is an 02 Sensor Circuit Malfunctoin (Bank 2 Sensor 3) problem.

take it to autozone or auto part store; have to pull your codes for you.

yes it will

Keith Heavilin had the right answer to the problem. Thanks again Keith!!! When i ran a scan on the jeep it came up po123, which is tps sig input a high. Keith told me to replace the clock spring and now it is fixed. He said this is a common problem on jeep grand cherokees. i wish i would have known this before i spent 100$ on a tps unit

i have a 2000 grand laredo jeep cherokee that is leaking fliud bad i think it the water pump how do i fix it ??

bulb holder fault or bad earth on light cluster ,try putting side lights on and then indicator if it all goes flashing between the two then its a dodgy earth connection .
