where is the crankshaft position sensor

Hello, this code does not mean you have a faulty sensor. It means there's a concern that the position sensor of the intake camshaft (cylinder bank 2) has a malfunction. This means testing is needed with the related components. I'd say replacing that sensor is like a 1% chance successful guess. Don't do it. Have testing performed by a professional.
