What does the diagnostic code P0320 mean for a 2001 Jeep Cherokee?

Answer 1

P0320 (M) No Crank Reference Signal at PCM No reference signal (crankshaft position sensor) detected during engine cranking.

P0320 (M) No RPM Signal to PCM (Crankshaft Position Sensor Signal to JTEC) A CKP signal has not been detected at the PCM.

The Sensor has failed. Replace the *Cam Position* Sensor in the Distributor.

***added by DrStoooopid You're half right. The sensor has failed, but there's two of them.

1. Cam position sensor, which is on the front of the engine. (location varies depending on engine)and is most definitely not in the distributor. There IS no distributor in those engines, they're electronically controlled. The cam position sensor sits .30" from one of the camshafts.

2. CRANK position sesnor which that code is referencing. The CRANK position sensor is the one that failed. (They usually fail in pairs though). The crank position sensor is harder to get to. It's on the back of the engine, near the transfer case.
