P0340

I keep getting this code. I changed my camshaft positioning sensor and alternator it was running fine until recently. I don't know what else to do.

Carefully inspect the wiring and the connector to the sensor.
This can also be caused by a failed PCM.

I've recently did ported heads and cams and have got the same code ever since. My car runs fine though besides the cel with p0340 code. I replaced alt, cam sensor crank sensor. Still getting code, guessing either I need another harness or a pcm. ****ty deal...let me know how yours works out for you and as soon as mines taken care of I'll let you know what was causing mine. Good luck this codes a nightmare.

It is often referred to as "The code of death".

Because it can often be a struggle to determine the cause.

Where did you buy the alternator from? Did you ever have the code deleted?

When I bought the alternator the code went away and everything was fine. Then one day it started acting up again it's just a little jerk in high speeds.

It might be a good idea to test the alternator. It wouldn't be the first time that a rebuilt alternator crapped out after a very short time...

My codes gone. Ended up being the adjustable cam sprockets from mmr. My sensor was to close to cam sprocket picking up the 5 Allen head adjust bolts along with the cam sensor bump.
