Ive seen many alternators on the edge gt's throw cam sensor codes because of a failed diode,actully I just did one last week.The harness from the alternator runs in the same harness as the cams sensor wiring,I havent seen one from an s197 yet though.Let us know what happens though.

Ugggghh, wouldve been to easy to have the alt be the problem. Scope test showed that it was working fine..... so, its not the alt. Wiring all looked good too. Guess that means me and my buddy are tearing into it this weekend. Gonna replace the cam phasers and the sensors and see what happens If this doesnt work for some reason, Im not sure what else to try. Funny thing, car "seems" to run fine.

if that doesn't do the trick, then it will
surely point to a wiring issue,
or maybe there is simply too much induced
voltage on the CMP sensor wires, from a source
yet to be determined

this sounds like an absolute PITA... are there a lot of people having this problem or is this a fluke thing?

Are the Ford ones just not good enough to get the job done ? I checked the cam position sensors and wiring (actually pulled the sensors to inspect them) and they all seem fine. I bought new cam phasers but not sure that will fix the issue either. Should I replace the sensors first ? Or do the sensors and the phasers while Im in there ? Car runs/sounds great.... Could it be in the tune ??? Please help this is driving me nuts. Thanks guys
Don't know if this article will help but it seems to me the OEM cam phasers are too sloppy for agressive or semi-agressive cams.

this is a fluke thing....there are at least 10
others (including me) that have no issues.
