DTC P1391 - Intermittent Loss of CMP (Camshaft Position) Or CKP (Crankshaft Position) sensor

Your Crankshaft or Camshaft sensor is not working properly. Needs to be checked out and maybe replaced; first try checking the wiring and harnesses (very common failures).

Code P1391, replaced camshaft and crankshaft sensors, plugs and wires, rotor, and a couple fuses, can a loose or bad distributor be the cause for this code?


DIAGNOSTIC TROUBLE CODE (DTC) P1391: "INTERMITTENT LOSS OF CMP OR CKP"
This DTC is monitored with the engine cranking or running. This DTC will be stored in the Powertrain Control Module (PCM) when the PCM FAILURE COUNTER reaches 96 failures for 2 consecutive trips.
Posiible causes are: Craknkshaft Position (CKP) sensor improperly installed, defective CKP sensor, defective distributor, defective Camshaft Position (CMP) sensor, defective PCM, defective or broken flywheel, defective connectors or defective wiring.
Proper diagnosis is recommended before replacing ANY parts.

2001 DODGE RUNS FOR AWHILE,THENS CUT OFF,IT WON'T CRANK BACK TILL BATTERY IS DICONNECTED,AND SITS AWHILE.I HAD THE ENGINE LIGHT CHECKED THE CODE WAS P1391.


The code p1391 is telling you that your ckp/cmp sensor signal is lost. What it is saying in normal terms is that the (crankshaft position sensor and the camshaft position sensor) are not sending a signal from time to time. That is why the car cuts out and will not start. First thing is to look at both sensors and check the wireing to each for any damage. The ckp is located on the front of motor on bottom side. The cmp sensor is located on the back of engine near the top. You have either one or both sensors that are not giving a signal to the pcm (power control module ). Hope this will help.
