Code 0340

[Uncle Buck]

CEL came on Friday. Reader says it's a code 0340 cam sensor. Everything I read says the sensor is probably fine but the alternator is about to puke.

Any suggestions for a replacement? Lots of noise on the web about how poor some of the replacements are, even OEM.

I have an email into K&P Electric as I hear he's very good.

Stephens 197 experienced the issue yesterday, Ross n I put an alt on it today, so far so good.
Gord is a good choice.
Ford clearly screwed up on the alt / reg circuit.
Suggest you do not attempt to drive the car as is (yes even if it's running ok).

What Rick said. I'll tell you all about it tomorrow at WNNOTC.

Thanks. I parked it right after it threw the code. Didn't want to add a tow to the repair bill. Besides I know these computers are fussy about voltage levels. Some have reported a wonky alternator caused all kinds of drivability issues long before it failed completely. Don't need a grumpy 3V on my hands.

Gord emailed me and suggested I bring mine in for testing / rebuild.

It'll likely check out as a diode issue back feeding the ECM. Like I said, ridiculous circuit that never should have been.

What car did get the code on?

So far so good with Ol Paint after the Dr. changed the alt. I'll tell you I was a lot worried Sunday night when I limped the car home.
