CODE PO839 ON A JEEP LIBERTY SPORT 4X4 - 2005 Jeep Liberty Sport

SOURCE: power locks on 04 jeep liberty not working

Most of the times on jeeps and all chrysler auto's they have a body control modual this is what controls your door locks , windows ect. It should be in the owners manual for all fuse location and identification. A shop with a scanner can check the door lock system for you. body control moduals go bad alot on all chyslers and if you buy one you need to buy it from the dealership they will program it . So check the owners manual for a fuse and then have the body control mod checked

SOURCE: I have a 2008 Jeep Liberty sport it has 39600 back-up lights not

If you have tested fuses and bulbs with test light,and they check out,
the next step is to put you jeep in reverse with the key on,and use your test light to probe the wires before they enter the bulb sockets for power,if you have power replace sockets,if not check to make sure wires are still connected to back up light switch on trans,if you find no problem there,replace the switch

Testimonial: "Thank you for the info on my jeep. I brought it to my mechanic and he could not find where the new switch goes.I will bring it to the dealer."

P0122 Code - Throttle Position Sensor/Switch A Circuit Low Input

A P0122 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 - 0.20 volts (V).

Did you adjust it when you installed it? If the signal value is less than .17V then the PCM sets this code. Could be an open or a short to ground in the signal circuit. Or you may have lost the 5Volt reference voltage.

Symptoms may include:
* Rough or low idle
* Stalling
* Surging
* No/little acceleration
* other symptoms may also be present

Causes: A code P0122 may mean that one or more of the following has happened:
* TPS not mounted securely
* TPS circuit short to ground or another wire
* Faulty TPS
* Damaged computer (PCM)

Possible Solutions: Some recommended troubleshooting and repair steps are:
* Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
* Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
* If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
* If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.


Hope helps (remember to rate this answer).
