Mein Auto: 528i
Error code P1397 2000 E39 528i

Hello Gentelmen !

Just looking for a little more info. Had a service engine soon light (comes & goes).
Had codes read @ auto parts store, only engine code found was P1397 "camshaft position sensor "B" circuit (bank 1) ?
Seems there are two camshaft position sensors, 1 on exhaust. 1 on intake ?

How can I determine which one to replace with the above info ?
Or should I just repalce both and be done with it ?
I did replace one sensor 3-4 years ago, located under the vanos area very front of engine.
Passenger side of engine.

Some other info to consider, high miles 279K still runs great, use daily, have some transmission issue (I think) intermitent shake/shudder at high speeds 60-75mph, mostly when lugging a hill or incline, comes & goes with no warning and not consistant. Seems like when cold out it does not happen. This is not the major issue right now however any help would be appreciated.

Sounds like you replaced the exhaust sensor (B). Was it a BMW part, or aftermarket? If the latter, these are known to fail.

Thanks for the reply Ed, yes it was a BMW dealer replacement sensor. Is the ehaust sensor the one for error P1397 ? or is the code the same for both intake and exhaust ?
Any help would be appreciated.

A and B refer to each sensor. You'll get an A code for the other one.

I'm puzzled by the code you read, since there are many codes that describe the sensor malady. Clear the code and see if it comes back.

There may be a wiring problem for that sensor. Carefully examine the cable for bad insulation or pinching.

Check the P15XX codes here: http://www.obd-codes.com/trouble_codes/bmw/

theres only 1 bank on the 528, i think the A and B designation is how they dictate if its the intake or the exhaust sensor

All is well in CT.
After a little investigation and a lot of help from the forum guys (thank you) I had the codes re-read at a "real" BMW shop. It was the Cam position sensor as codes said, replaced it and it's back to normal with no dash warnig lights on. A couple hundred lighter i the wallet now... no big deal really. Thanks agai guys !
