Which Cam Sensor?

[tsydej1]

Hello, I just bought a 01 330ci two weeks ago. Anyways my CEL light came on. I checked with my scantool. Code P0365. Cam sensor B bank 1. After much investigation I learned this is a very common problem. So I call my local BMW dealer and they want 135 for the sensor. My problem is that from that error code I cannot tell which sensor it is(intake or exhaust). I told the parts guy it said sensor B bank 1 and he was like that doesn't help me at all. And I dont want to replace the wrong one, so could someone tell me which one is giving me the error code, or what I can do to verify its one or the other. I need to drive 300 miles and dont know if i should chance it. thanks.

"B"is always exhaust(easier one to replace) and "A" is always intake side...
PO365 is exhaust sensor(B). PO400 or PO340 (A) would be an intake one as a generic code for BMW.

had the same problem in my "01" 300. It was the intake side for me.

go to a oil changers 3000 and have them read the code. Their reader will tell you which one to replace. I think theres a different code for each sensor.

Seeing how that code doesnt match my old one ima go with what zibby said..its the intake side. goodluck with the swap.

You would think the parts guy would know that. Thanks a bunch!
