20 Most Recent 1994 Jeep Grand Cherokee Questions & Answers


These conditions MUST be ruled out entirely.
Check for any of the following conditions/mechanical problems.
AIR INDUCTION SYSTEM - must be free from leaks
ENGINE VACUUM - must be at least 13 inches in neutral
ENGINE VALVE TIMING - must be within specifications
ENGINE COMPRESSION - must be within specifications
ENGINE EXHAUST SYSTEM - must be free of any restrictions or leaks
ENGINE PCV SYSTEM - must flow freely
TORQUE CONVERTER STALL SPEED - must be within specifications
POWER BRAKE BOOSTER - no internal vacuum leaks
FUEL - must be free of contamination
FUEL INJECTOR - plugged or restricted injector; control wire not connected to correct injector.

Unfortunatly, a scan tool will be required to monitor o2 sensor voltages while the engine is running in closed loop. This code you are displaying is NOT an easy solution to trace down. I expect you had an exhaust leak and is why the cats were replaced? Anyway, if so, the PCM can reset the light after a few GOOD trip readings occur that will satisfy the PCM's no fault signal, otherwise the JEEP dealer is going to be your only solution and a pressure test should be performed.

You have a blown power booster. It is leaking vacuum and you will have a hard brake pedal and find it tough to stop your vehicle. Replace the power booster and you will have brakes and no more leaking air sound.

I'm having a problem with my tranny not wanting to shift automatically at all. Seems like a dead stop its stuck in low gear. Have to manually shift and does not go into overdrive. I have a 1993 Jeep Grand Cherokee. Can anyone help me cause I've swiched out throttle control sensor, filter change, new tranny cooler and heavy duty lines. I'm at a loss and scratching my head. Any advice would be greatly appreciated

first place I'd look is around the perimeter of the heads (I assume you mean head gaskets?) Make sure you haven't inadvertently gotten a wire pinched in between the head & block somewhere.

I would try finding all the ground wires on the vehicle and cleaning them to make sure they are getting a good ground. 12 volt systems are very sensitive to bad grounds. I seriously doubt that turning on the light had anything to do with it, but a bad ground could give low voltage to the radio, relays, etc. and make them turn on and off. The more things you turn on the more the bad connection will give problems. I hope this helps.

try disconnecting the NEGATIVE cable on the battery for 10-20 minutes. re-connect it. start the vehicle and drive it for a few miles to let the pcm reset. (make sure the key is off and out, just to make sure you don't fry something when you remove the negative-black wire cable!!). don't short it against the positive-red!
make sure the negative connector (on the cable) is isolated from the frame, or it will still be grounded! wrap some plastic around it, or something!
good luck!

so all 3 FOBs are dead? is that it??????
so the which part of the system is failing
the ASD relay cuts starts, 7 ways, one is security. called VTSS.

i guess the security light is telling you, that it is not happy? in the dash cluster, is that it?
94 or 96?
so it , flashes ext. lamps, honks horn, and wont start.
page 8q-1 FSM.

endless post. on topic. read it, try it.

better yet, diagnose it.
scan the PCM to find out why the ASD relay drops out
does it? that is the first test in all, no starter.

if the battery is discharged, bad things happen as the security logic
goes nuts. (the chips dont yet run on "free energy" )

Change your compressor with the new one.

1994 Jeep Grand... | Answered on Feb 23, 2018


no
that is a boot retainer clip and should be attended to as ir prevents dirt getting into the joint
There is a wire around that point that goes to a sensor got the ABS and it may be loose or damaged
have the boot checked out and if it is cracked have a drive line shop replace it

Check your exhaust many times it'll be a o2 sensor wire touching the manifold causing the short to ground. Start there let us know. Hope this helps.

Have you checked it for engine codes? Trouble codes should point you in the right direction.
