Thought I would through this one out there and see if anyone has any opinion or experience with this.
About three weeks ago my 02 GT started logging a P0340 DTC (Camshaft position sensor fault). The only problem symptom is that sometimes the engine will start and then immediately die when first cranked. When this occurs it never fails to start and idle normally on the second crank attempt.
Well, since the CPS is relatively cheap and easily replaced, that was my first thing to do. The DTC was cleared and all looked normal until the second warm-up cycle of the engine, when the DTC was logged again. I disconnected the battery for 1/2 hour and let the ECM re-initialize itself. It then went about eight warm-up cycles before logging the code.
On the surface, it appears I have an intermittent fault in the CPS circuit somewhere. I'm also wondering if there is some other condition that may be inducing a false P0340 code.
I would appreciate any opinions.
