Here is what the service manual says:

"No Crank Referance Signal at PCM - No reference signal (crankshaft position sensor) detected during engine cranking"

OR

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

What does this mean?

 

[James K]

you have a bad sensor

I forgot to mention, when I started my WJ it was shaking and when I pressed on the gas nothing happened. The tach wouldn't even move. It also had a bad idle.

 

[James K]

the crank position sensor went out on my cummins about 2 months ago. and it did similiar things to what you descrbe on yours.

the tach would work sometime and would idle rough even died once :-\

 

[James K]

let me add that mine was pitching out two codes also but both pointed to the crank position sensor.


I think if you replace that all should be good....................but then again I have been known to be full of sh!t

Sounds like it.....CPS. Not too hard to change. I'd never NOT buy one from a dealer again, though.

It should only cost me $125 or so with labor

That's about the dealer list price if I remember correctly........ I'll never NOT put another dealer sensor in any of my computer controlled vehicles. Too expensive
