Fault Code P0340

Is the fault code P0340 for the intake or exhaust cam position sensor?

It's for the S54 motor (2001 E46 M3)

Thanks

I believe it is the intake -
SAE Code P0340
BMW-Specific Code 65
Description Intake Cam Position Sensor Malfunction

I searched for the code here:

I also found this searching for BMW ODBII code P0340 on yahoo looks like a pretty good site for codes -

Thanks for the info. The links you provided are very helpful.

I'll replace the intake CPS.
