Okay, couple of problems I'm hoping someone may be able to help me out on here.

First off it's on a 2003 dodge diesel with 174,000 km.

I was under the truck the other day trying to track down the problem to codes P0341 and P0532. Just going off memory but I beleive that's what they were. Cam Position sensor and ac low pressure sensor I think is what they are. I had read about all the problems with the wire rubbing on the ac line so I was checking it out. Wires past the loom seemed to be okay. Haven't checked under the wire loom yet though. Next I was looking for the cam position senor. Had a heck of a time getting to it but by feel I think I've found it. While under that side though I noticed a loose bolt stuck in behind the ecm. Got a pair of needle nose pliers in and managed to get it out but I don't know where it's come from at all. It's very similar to the allan screw that holds the cam and crank position sensor in place.

Here's a picture of the allen screw that I'm talking about. It's made of alluminum with what looks like a metric 5 allan head. It also has a thin o-ring around it.

Any other ideas on the codes coming up? It sure seems like all of the other posts about the problem but so far I haven't found any bare wires. Are there any other posible spots that are common for them to rub threw at all?

What started this all is the truck was getting harder to start. Have been blaming it on the injectors but while reading I got to wondering if this wasn't contributing the the problem. Dodge did 3 injectors a year ago under waranty I wanted them to do them all because I said the other 3 are just going to fail and chances are I'll be on my own then. They just said yes you are most likely correct.

I'm sorry for the mixed up rambling post but hopefully someone here has a couple of ideas that can help me out.

Thanks

Ryan
