My son's 2013 Fr-S has finally experienced its first check engine light. The code is P0390 Camshaft Position Sensor Bank 2 Circuit B.

Can one of you FR-S/BRZ Gurus tell me which side of the engine is Bank 2 and if Circuit B indicates Intake or Exhaust?

The auto parts store reset the code so we will see if and when it comes back on and then I intend to do the repair. It will be my first time working on a Subaru engine but I have worked on engines my whole life and maintain and repair all the family vehicles.

Thanks in advance for sharing your knowledge.
