Default Camshaft position sensor problems

Hi,
I have a 2000 3.0 automatic and have been having some problems lately. The truck bogs and surges from idle to 2000 rpm, and runs fine beyond that. It finally threw a code so i put the computer on it and came up with the sensor. I replaced it, cleared the codes, and the truck ran fine, until i drove it in misty/ wet conditions, where it started doing the same thing all over again (code and all). So i have replaced it again and repeated this cycle. What im thinking is that it is probably wiring running to the sensor that gets wet. What i am wondering is how much can it hurt my truck if i drive it for awhile until i can get home (at college right now) and throw it on the lift and go through all the wiring? Thanks for any input!

Well, if it's throwing a code for CPS, then I would just get a wiring diagram and follow the route of the wire that feeds it. There's no need to go over the whole harness unless it was hacked by a previous owner or you submerged the truck in water. Driving in wet conditions shouldn't cause any problems with the top end wiring unless you were puddle jumpin, or if a significant amount of water was getting into the gap between the hood and cowl and splashing right onto the CPS.

So.... Are you sure you installed the CPS correctly?

Did you replace the CPS and the sync? Did you hear any chirping the first time you had a problem?

I have heard some small amount of chirping when the truck is cold but that sounds like it is coming from the belt. I do plan on following the wires that lead to the cps and i did install it correctly, or so my dad says as he is a auto mechanic. Now thinking about the chirping, it worries me about the sync. man this sucks being away at college, lol

Quick check is to pull the belt off and start the truck.If you still hear the chirp, your sync is bad. Unfortunately, you can't wait on the Sync to get worse, as losing oil pressure is not fun, especially when you're in the middle of traffic.
