What triggers the Cam position sensor??
Between the last lifter lobe and rear most cam journal is a reluctor wheel of sorts. Doesn't look like your typical square tooth reluctor wheel but that is what triggers the cam sensor. Looks like a big bolt thread with only one rotational pitch on it.
Hope this answers your question.

Actually I was wrong with my description. Just ignore the part about the big bolt thread...it is actually a ring with the sides offset.
And it is machined from the same solid billet stock that the rest of the cam is machined out of. Meaning it is all one piece. Other that physical damage while the cam is out of the block I don't see how it could come apart.
I would check the cam sensor first.

I would check the pin assignments on the PCM...

Check the connections and grounds. If the wires are fine, and obviosly there is no problem with the reluctor ring on the cam itself, then that leaves the actural cam position sensor.
I'm sure you know where the cam position sensor is, but if not, here is a pic...it is #2...
It may be a bad cam pos. sensor since the knock sensors have gone bad from water getting in there and the CPS is in the area...hope it helps...

The link shows the diagram to be for a 98 PCM, I beleive the 99's were different, I have already replaced the cam sensor once........
