Question about 2002 Jeep Liberty

2 Answers

Codes don't show up

I ran a diagnostic tool for my Liberty 2002 because the engine light came on. It showed the codes P0500, P1507, P1540 but there's no info on the codes on the Jeep site. Any help is appreciated.

P500=Vehicle Speed Sensor Malfunction (VSS)
p1540=VSS Signal Too High
P1507= Vehicle speed/Idle Speed Actuator
Speed sensor is faulty or has a bad connection.

    To start, check the connection on the VSS on the trans. Make sure it is clean and secure. Do you have an OBDII diagnostic scanner? If not, you can try replacing the VSS. I would also like to add that the code p1507 is related to the VSS code. Don't replace the idle speed actuator just yet.

It could be a change in software from 2002 to 2003. You might try to get. Hold of a 2003 black box as the code will most likely be different.

Need my Liberty to pass smog I recently had codes po445 and po442, will this be a problem for passing smog if check engine light isn't on? Not sure if problem was resolved with new gas cap.


if your check engine light isn't on, they will still hook up a diagnostic code tester to your vehicle to see if the computer has picked up any problems, if the computer has picked up a problem, and you fixed the problem, then you can have the code removed from the system, with a diagnostic code tester.

I have a 2002 ford taurus. check engine light is on. Auto Zone did a scan today and the error code was p1507 can you please tell me what i need to do to fix this problem.


possible problems

Vaccuum leak
failed IAC valve
open or short
air inlet plugged

P1507 means "Idle Air Control Underspeed Error". It can be most commonly caused by a vacuum leak, a damaged Idle Air Control (IAC) assembly or a stuck IAC valve that needs cleaning. Essentially, your engine isn't idling at high enough according to your computer's programming parameters. Many times this shows up in colder weather as you try and start your vehicle. It will usually die unless you put your foot on the gas pedal and raise the RPM's. I have also read where a clogged air filter might be the problem. I would try cleaning your IAC valve first.

2002 jeep liberty speed sensor


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.
