Fault (018) 12 - signal exhaust camshaft sensor - signal not plausible

Hi, I have presisting problem with my e46 m52 1998 320i.



Under 3k rmp feels like have no power. DIS say:



- (018) 12 - signal exhaust camshaft sensor - signal not plausible

- then some misfires in 6 cyl.







I have replaced both cps (intake exhaust) with used BMW parts. I have done new seal on vanos (beisansystems), but the code is still here.



I found this video:

This clicking noise sometimes happend to me. In this case it was exhaust solenoid. Could this solenoid cause P1397? Thanks for help, and sorry for my english :-)_a_
