What does the diagnostic code P0320 mean for a 2001 Jeep Cherokee?
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.
How does a diesel engine pickup a tach signal?
From a crankshaft speed/position sensor.
How do you repair the crank signal so that the engine will continue to run?
replace cam position sensor
What does the cam position sensor control on a 2000 Chrysler Concorde 2.7l?
It sends a signal to the engine computer to tell it the rotational position and speed of the camshafts. The computer uses that information for fuel and spark timing.It sends a signal to the engine computer to tell it the rotational position and speed of the camshafts.

How do you troubleshoot a fault code 54 on a 1997 dodge stratus?
Code 54-No cam signal at the PCM-No camshaft position sensor signal detected during engine cranking.
What does a Code 11 mean on a 1994 250 dodge van?
No signal from crank position sensor during engine cranking.
What is a VW Jetta engine speed sensor?
The engine speed sensor provides the ECM with a crankshaft position signal. The ECM uses the signal to determine a crankshaft reference point (Top Dead Center) and calculate engine speed (RPM.) The signal is also used by the On-Board Diagnostic system for misfire detection. The ignition system will not operate if the ECM does not receive an engine speed sensor input.
How do I test crankshaft position sensor on 2000 gmc safari van?
You would need to scope the signal, using a scanner tool with a scope function. With this you can look at the signal to the ECM while cranking the engine.
Where is the best place to look to find the position of a crankshaft sensor on an engine?
Most are near the front pulley of the engine. Some are located in the bell housing, they pick the signal up from the flywheel.

Does the coolant temp sensor on a 2002 cherokee control the radiator fan relay?
The engine computer uses the signal from the coolant temperature sensor to decide when to activate the radiator fan relay.
What are the symptoms of a bad camshaft position sensor in a 2000 Skoda octavia?
The Camshaft Position Sensor is used for ignition timing and determining the RPM.As the signal is needed for proper fuel injection, the fuel injection stops whenever there is no signal. Also the RPM meter drops to zero.It is possible that the signal drops out for one or two seconds, and then resumes. In this case the engine will stall during the dropout, and (when not in idle) resume operation when the signal resumes. It is very well possible that no error condition is logged by the Engine Control Unit (ECU).If the signal is completely gone the engine will not run or start. In this case an error code will be logged.
