Default CEL code: 0340 / Camshaft position sensor

I did a search and found that some have gotten this code before.

I got one recently and was wondering what the conventional wisdom is on possible causes. The CEL went on during an engine overrev situation that resulted from a 5 to 4 downshift that mistekenly ended up in 2nd at about 90-100 mph. Ouch.

But there doesn't seem to be any permanent damage, and others have gotten the same code from just regular everyday driving.

Is this code something that might be thrown just because of extremely high revs? Is it caused by something else entirely?

Any help would be appreciated.

Jay

That's one of the ones I had and it would go and go off at various intervals. Subaru Canada took the car for a few hours and ended up replacing the whole ECU.

I've never had the light since.

So they had no idea what was causing it basically?

I guess I'll wait and see if I ever get another one before worrying about it.

What I'd really like to know is the answer to this question:

Would extreme overreving, such as in the 8k-9k rpm range, cause this CEL?

I don't know, but my light never came on while I was driving hard. It was at stupid times like sitting at a light, or driving slowly in my underground parking. Once, it came on while cruising on the highway.

Thanks for that link, Jon.

Funny thing is, when we pulled the 0340, we also got a 1443.

I recall that the CEL has gone on and off about 5 times already, and I assumed that I had the one 0340 from the overrev, and that the other incidents were 1443s.

Mulder helped me get the codes with his autoxray code scanner, and we coudn't get any additional information, such as number of codes, snapshot info for the 0340, so it's really anyone's guess what code came from where.

I realize from reading your post that I could be totally wrong about my assumptions.

In any event, I think we should take this discussion to that other post, as linked above, and again here:

It has a lot more information on the topic.

Question possible reason?

I guess it is certainly possible that the CAM sensor can not keep up with the CAM shaft. I do know that many sensor do have a limit in sampling rate, so if the cam is rotating above the upper limit, then it might produce a voltage/code that the ECU can not understand. It also could be possible that the ECU is programed in a way that will give out CEL when a over-rev situation was picked up too.
