20 Most Recent 2006 Jeep Liberty Questions & Answers


You need to take the jeep to a dealer or a good mechanic who can retreive the codes out of the computer. You may have a module problem but I will not guess without knowing the codes.

Replace the crankshaft position sensor and you should be up and running like normal. Verify that there is no power or ground problem to the crankshaft sensor, the Yellow/Black wire should have battery voltage any time the key is on and the main relay is energized.Verify that the Brown/Yellow wire has a good ground. If all is good then replace.


P0335 - Crankshaft Position Sensor A Circuit Malfunction
The crankshaft position sensor (CKP) measures crankshaft location and relays this information to the PCM (Powertrain Control Module). Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. The CKP sensor is stationary and works in harmony with a reluctor ring (or toothed ring) that is attached to the crankshaft. As this reluctor ring passes in front of the CKP sensor, the magnetic field created by the CKP sensor is interrupted and this creates a square wave voltage signal that the PCM interprets as crankshaft position. If the PCM detects that there are no crankshaft pulses or if it sees a problem with the pulses on the output circuit, P0335 will set.

Symptoms:
NOTE: If the crank sensor is used only for misfire detection and NOT spark timing (this varies with the vehicle), the vehicle should start and run with MIL (Malfunction indicator lamp) illumination. Also, some vehicles require several key cycles to illuminate the MIL. If this is the case, there may be no MIL illumination until the problem often enough over time. If the crank sensor is used for BOTH misfire detection and spark timing, the vehicle may or may not start. Symptoms may include:
Vehicle may not start (see above)
Vehicle may run rough or misfire
MIL illumination


A P0335 "check engine light" code could be caused by:
Damaged CKP sensor connector
Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
Sensor output open
Sensor output shorted to ground
Sensor output shorted to voltage
Failed crank sensor
Broken timing belt
Failed PCM

Possible Solutions:
Using a scan tool, check if, when engine is running or cranking, that there is an RPM signal.
If there is no RPM reading, then visually inspect the crank sensor and connector for any damage and repair as necessary. If there is no visible damage, and you have access to a scope, you could check the CKP 5 Volt square wave pattern. If you do not, then, obtain a resistance reading of your crank sensor from a repair manual. (There are so many different types of crank sensors that there's no way to put here which resistance reading is correct). Then check the resistance of the CKP sensor by disconnecting the sensor and measuring resistance of the sensor. (It is best to check resistance readings from the PCM connector. This rules out any wiring problems from the start. But it does require some mechanical skill and shouldn't be performed if you\'re not familiar with automobile electrical systems). Is the sensor within resistance specs?
If not, replace the CKP sensor. If so, recheck resistance reading from the PCM connector. Is the reading still okay?
If not, repair open or short in the wiring to the crank sensor and re-check. If the reading is okay, the problem is intermittent or the PCM may be at fault. Try reconnecting and checking for RPM signal again. If there is now an RPM signal, wiggle test the wiring harness to try and induce the fault.

This code is basically identical to P0385. This code P0335 refers to Crankshaft Posistion Sensor "A", whereas P0385 refers to Crankshaft Position Sensor "B". Other crank sensor codes include P0016, P0017, P0018, P0019, P0335, P0336, P0337, P0338, P0339, P0385, P0386, P0387, P0388, and P0389.


Hope helps.

When changing the fuel filter and air gets into the system, just turn the key on and off a couple of times and the air will be push out through the rail into the tank. There is no special way to get air out of fuel system in a gasoline engine. If it was a diesel you can crack open a fuel line by the injector and let the air out. Most diesels will have a bleed valve by the fuel filter.

When it does not start, spray some starter fluid in the throttle body. Then if it starts you know you have a fuel delivery problem. Could be relay or connections.

You can drive in 4 high at any speed you would drive in 2 high as long as you are on a loose surface,never on a dry surface.

Test for power and ground at the clips. If you get that, then you have a crack in one of the grid lines.

If you mean a repair manual you must purchase it from the dealer.
