I have a 2002 Jeep Liberty and the oil pressure light comes on in the mornings when it's cold. It doesn't happen when I'm moving, only when I'm stopped for more than about 5 seconds (so not in stop & go traffic, more like at stop lights).
This just started happening about two oil changes ago. I took it to the shop the first time and they spent 2 hours trying to diagnose and/or repeat the problem and couldn't. They charged me for the diagnostics ($110) and their solution was engine oil additive.
I would like to know if:
a) anyone else has had this issue
b) what the root cause might be.
The additive is working, but my fear is that it's a band-aid and something worse will happen down the road if I don't take care of the root of the issue soon.
Chrysler mounted the oil sensing unit on these motors directly above the oil filter. It is very easy to accidently hook the sensing unit with the oil filter wrench and crack or break it. For anyone whose oil light problem developed right after an oil change, this may be the problem. To change the unit, pry up the plastic retaining clip with a screw driver and unplug the wire harness. If the plastic part of the sensor is broken, (or if you break it to facilitate easy removal), you can remove the sensor with a 27mm socket. Once you have removed it, use a piece of CLEAN pipe cleaner to insure the hole isn't plugged with sludge which could also cause the oil light to come on. Screw in the new unit finger tight, then snug up with a WRENCH. You cannot use the socket to tighten it as it would damage the plastic part of the new sensor. Plug the wire harness back on, then start the engine to make sure it doesn't leak oil around the new unit.

Check engine light is on, no speed ohmmeter or odometer working. Took it to auto zone for diagnostic test....they are telling me speed sensor. Where is this located? By looking at the part it looks easy to replace. Help please.

Jeep Liberty 2002 woahs !
by porth21 - 2/1/09 7:35 AM In reply to: Jeep Liberty 2002 speedometer not working by Dannywon
I have a 2002 Jeep Liberty Limited with the same problem. The main problem I have found to be the routing of the speed sensor wires located on the rear difrential. They are 2 blue wires on my jeep and probably the same on yours. The problem is that they rub on the E-brake cable and once the wire is exposed they short and the speedometer and any other options running off they speed sensor quit working and that includes the tranny shift points and can cause the torque converter to not unlock and cause stalls. I am having the same problem for the third time and chrysler and jeep are both aware of the problem and unwilling to repair the problem or post a recall.

jb power fuse drains battery
Posted by wilcoxon1 on
The JB fuse under the hood is the power supply for the fuse box inside of the vehicle, if the battery drain goes away when JB fuse is removed is only because you have isolated the interior from the rest of the vehicle. These vehicles have issues with the body harness connector on the drivers side floor. To access the connector remove the rear seat and pull back the carpet, the connector is located directly below the drivers side rear seat bottom. Unscrew the 10mm bolt that holds the connector halves together and inspect for corrosion. If corrosion is present, repair as needed and your battery drain should go away.

Okay, this is driving me nuts! I have a 2002 Jeep liberty with a blown 3.7L engine. I am going to replace it, but am having trouble finding a 02/03 engine around here locally. I find plenty of 04/05/06 3.7 engines and was wondering if I would be able to drop one of those in? I understand they have different crank reluctor wheels and possibly cam reluctor wheels. I was thinking of putting a 04 engine in and then also swap my PCM for a newer 2004 PCM with the later engine tune that should be calibrated for the 04 engine. Does anyone have any knowledge if this should work? I would expect the wiring harnesses to be the same between the 02 and 04 engines and would think everything would just bolt right up and fire up. Any input would be greatly appreciated, thanks!
Has anyone made this work yet? I have the same problem 2002 jeep 3.7 and just installed a 04 motor. Timing is off. Some one had a good idea of mounting the crank gear to the out side of the harmonic ballancer and mounting the sensor with a bracket. What about the cam gear on the left side. Does the timing cahain have to come off to remove it? Or has any one swaped the wiring harnest, and computer.
Please email me back. [email protected] Thanks for your help.

how to set the timing marks on the cams on a02 jeep liberty 3.7 engine
Posted by Wilma... on
CAUTION Plate behind left secondary chain tensioner could fall into oil pan. Therefore, cover pan opening.
CAUTION Care should be taken not to damage camshaft target wheel. Do not hold target wheel while loosening or tightening camshaft sprocket. Do not place the target wheel near a magnetic source of any kind. A damaged or magnetized target wheel could cause a vehicle no start condition.
CAUTION Do not forcefully rotate the camshafts or crankshaft independently of each other. Damaging intake valve to piston contact will occur. Ensure negative battery cable is disconnected to guard against accidental starter engagement.
CAUTION The silver bolts retain the guides to the cylinder heads and the black bolts retain the guides to the engine block.
NOTE The idler sprocket must be timed to the counterbalance shaft drive gear before the idler sprocket is fully seated.
NOTE It will be necessary to slightly rotate camshafts for sprocket installation.
CAUTION Remove excess oil from the camshaft sprocket bolt. Failure to do so can result in over torque of bolt resulting in bolt failure.
CAUTION Ensure the plate between the left secondary chain tensioner and block is correctly installed.
NOTE Left and right secondary chain tensioners are not common.
CAUTION After pulling locking pins out of each tensioner, DO NOT manually extend the tensioner(s) ratchet. Doing so will over tension the chains, resulting in noise and/or high timing chain loads.

I have a 2002 Jeep Liberty Limited, 3.7 L motor. The heater will not blow hot air. The A/C and fan work well. When I turn the temperature dial to hot, there is only cold air coming out. Can you assist me?
Jeeps are notorious for having broken temperature control (Blend Air) doors. A malfunctioning Blend Air Door actuator probably caused it to break. The dash will have to be removed to replacethe door and the door actuator.
