P034062 The position sensor for the intake camshaft (cylinder bank 1) has an electrical fault. The signal comparison is faulty.

that is the code i got.

if the proper tests fail here are the common results

Possible causes and remedies

  • N10/1f22 (Electrical fuse 22)

  • Electrical lines between control unit 'N3/10 (ME-SFI [ME] control unit)' and component 'Y49/1 (Intake camshaft solenoid)'

  • Y49/1 (Intake camshaft solenoid)

so it appears to me like you have a faulty cam solenoid. what is the diagnosis they came up with?
