RE: HELP PLEASE!!!!!! - 6/18/2008 8:05:04 PM    shawnvw   Posts: 1093 Joined: 1/18/2008 Status: online what was the fault code for the first one? there should have been a number that came along with the code. (Example P0301) Sounds like they are using a generic scanner which is why is comes up as manufacturer control. If you can get the fault code, we can look it up and give you more direction _____________________________ If you have a question, ask it in the forums.

RE: HELP PLEASE!!!!!! - 6/23/2008 11:16:10 AM    rbarrios   Posts: 225 Joined: 2/1/2007 Status: offline A P1345 is a crankshaft/camshaft relation code. The sensors is used by the PCM for timing functions. They are basically a voltage inducer, triggered by a reluctor ring on the crankshaft and the exhaust camshaft. My manual suggests going to the dealer for a new position learning procedure when ever one is disturbed the above I found at trailvoy.com theres a thread on this code there... http://forums.trailvoy.com/showthread.php?t=26897&highlight=p1345&page=2 (in reply to Trailblazer23) Post #: 8
