Scott,

Looking at your original post, I don't think that the engine position sensor is the cause of your problems.  Looking at the causes of the codes all point to voltage problems (plus the charge light illuminated on the dash).  I think this is either a harness, plug or maybe even a module problem (ecm/pcm) Hopefully not.

I need to sign off right now to go to a viewing, but I'd like to research this some more, and possibly help locate the problem

I'll PM you tomorrow, once I get a chance to look deeper

Tom, what he is describing is exactly what mine was doing. Once I replaced the sensor, everything was fine.

If all the codes were coming active at the same time then yeah I'd say that too. But looking at the wiring diagram, the camshaft position sensor has its own 5v and ground to the ecm. It doesnt share the same 5v ref and common ground that the EOP, IAT, ECT, WIF, and MAP do. Just thinking those other codes were i/a from a while ago and the Cam code is the one coming up right now. Be nice if you could pull a time stamp on the codes though.

The only code being thrown now is the p0381.  And the light is the check engine not the charge light. But if you do have any other ideas I'd be glad to listen.

Mayfair, I may take it in.  I also have a friend that does a lot of work on trucks so he may do it for me.

Before you said that the code was the p0380.  If it is that one then all you have to do is clean the wires on the relays for the intake grid heaters.  It is a real simple fix.

Got them mixed together.  It's p0341.

with just the one code, then it probably is the sensor

multiple codes before had me looking elsewhere...

Weather is perfect for working on the truck so I have decided to take on this little priject. 
Found the sensor with no problem.  Got the bolt out with no problem (it is a hex-5.0mm(allen head)). The new one is threaded all the way from the tip to the stop so I started to turn.  It hits the block!!  Does anybody know if it is supposed to plull straight out?  :argh:  The Manual says:
Quote
REMOVAL - DIESEL
The camshaft position sensor (CMP) is located
below the fuel injection pump (Fig. 9). It is attached
to the back of the timing gear cover housing.
(1) Disconnect both negative cables from both batteries.
(2) Clean area around CMP.
(3) Disconnect electrical at CMP (Fig. 9).
(4) Remove CMP mounting bolt. Bolt head is
female-hex (Fig. 10).
(5) Remove CMP from engine by twisting and pulling
straight back.
(6) Discard CMP o-ring (Fig. 10).

It's tough to get a hold of and I don't want to break it and not be able to remove it. 

Thanks!!

Oh, and as much as I would love to take pics, that's not happening unless the engine is out or I cut out a section of the fender.

Why don't you just take out the inner fender liner?

Makes getting to everything on the side of the engine much easier.

the sensor should pull out after remoing the bolt (it has an o-ring on it, and that's probably what's holding you up)

Ok after a little thinking we took a piece of twine, wrapped it around the connection part of the sensor and POP!  It came right out.  If I didn't have trouble with it being in so tight it would have been a 15 minute job.
But a little bad news. There is oil on the old one.  I am going to guess there is a bad gasket in there somewhere.  I'll also bet the sensor isn't bad, but the oil was causing it not to read prperly.

It functions in an area that has oil splashing around - oil on the sensor is normal - that's why it has the o-ring - to keep the oil in

That's good to hear.  Now that I think about it, that;s how my mifes suv and my old Nissan truck were.  I was thinking of my car, which has a crappy belt, and oil there is a bad thing.

Thanks for all the help and input guys!
