Ok, here's the deal. 2002 Gt, P0340 code comes up. Changed the Camshaft Position Sensor and had my performance guys scope out the wiring - everything looks good. Days later, the stinking light comes on again and the car turns over and dies right away on start up. Then, once the engine is started, if I don't rev it up before driving, the engine will die and I get a HUGE backfire. The CEL is on again with the same P0340 code - "Camshaft Position Sensor, Bank 2".

Got 96k on the OD, never changed plugs, just changed the EGR Valve. BBK shorty headers, Cat-less BBK X-pipe.

Any ideas?

Thanks in advance!

replace your alternator, do a search on here and sea ALL the people who have gone thru the samething and replacing the alternator is the fixx

Yeah, I saw the thread on that. Just wanted to confirm before I spent the money on a new alternator.

Well, just to confirm - it was the alternator. The stupid thing crapped out on me last night. Had the dealer change it out for me, along with replacing the plugs, fuel filter, and cleaning the carbon deposits out of the throttle body, intake, and egr valve.

Purrs like a brand new pony now. No start up problems, smooth idle, and most of all - no P340 code coming up anymore.

You guys know your shiznit.

Thanks!

My 2003 stang is showing the same symptoms as everyone else here. Same P0340 code, already changed out CPS and belt. Right before my engine cuts off i hear a loud squeel kinda like rusty metal. Is there any way it could be something relating to the pulleys or bearings. Might end up taking it to the shop sometime this week when I get some time. In the meantime maybe you guys have some possible answers.

Sounds like an alternator bearing about to seize up. Agree with Randy. Replace it soon!.
