 Exhaust camshaft sensor
I have a 2000 Z3 with the 2.3. I had a check engine light on and kept checking the gas cap--it would go out after 3 starts. Had light checked out at Autozone and it was a P1397: Camshaft Position Sensor "B" Circuit (Bank 1). I understand that this is the exhaust sensor, which is the cam sensor without the pigtail. I have been searching and understand that it is easy to change from the front of the engine. I have looked and find how to change what I think is the intake sensor. Is there a url for the exhaust sensor? Are my conclusions correct above.
I am new to this site and would appreciate any advise and help.
