P0340 ??

Hey guys,
I recently replaced my camshaft positioning sensor when I received the p0369 code. It went well for a couple days than my check engine light appeared again, but this time it read p0340.

Is it a faulty sensor i must have used? Or am I in need of a complete different sensor.

Thanks for your help.

I believe P369 is a failed exhaust camshaft position sensor. I should know it. Mine failed three times, each at about 12,000 miles.

Not sure what code P340 is though.

P0340 is intake cam position sensor.

Do you know where each one is located. I'm not sure which is which?
I replaced one, but I may have mistaken.

Exhaust & intake sensor.

The exhaust camshaft position sensor is on the right front of the engine from the drivers seat & a 15 minute replacement.

I believe the intake sensor is under the exhaust manifold & more difficult a replacement.

Damn, I realized I changed the intake sensor instead of the exhaust sensor.
I just ordered the exhaust sensor, but do you guys think I should put my old intake sensor back on since the check engine light came on for it ?

Thanks

Hey Z3, if it were me,I'd leave the new one on and keep the old one as a spare. Why go thru the hastle of changing it again with the the looming threat of maybe it going out on you? Your car...your call.

Problem fixed ! The exhaust sensor was very simple to replace.

No. I've never had an intake sensor go out on me - ONLY the exhaust sensor.

Don't replace what you don't have to - especially with these sensors.

When I replaced my intake cam sensor, I disconnected the battery first and reconnected it afterwards so the computer would be reset when I was done.
After replacing the sensor with an aftermarket one, she ran GREAT but the light was still on so I figured it was something else. well, about two weeks later it started getting harder and harder to start to the point where now it's a crap-shoot if she'll start or not. And when she does start, she runs rough for a few moments then smooths out. Any ideas?
