Question

Engine management light on gave reading above, what could resolve this problem

Answer 1

P0012 Camshaft position A timing over retarded Bank 1

The best resolve is to replace the camshaft actuator solenoid, this would be the intake side on Bank 2 , what commonly happens after so many mileage and use its ability to regulate oil pressure is just no longer effective , it wears out.
