What is the reason for the P0012 camshaft position A timing retardation?

[RowanAnn]

p0012 camshaft timing retardation reasons are as follows: 1. Low octane rating: Low gasoline octane rating or engine disengagement causes engine misalignment, resulting in camshaft retardation and altering the position sensor signal data. 2. Stuck: Oil pressure control valve (OCV) stuck. CVVT actuator gear mechanically jammed. 3. Wear: Oil pump wear, oil pump pressure regulating valve stuck, or system blockage. 4. Belt issue: Incorrect timing belt or chain alignment. 5. Wiring problem: Abnormal current in CVVT control circuit, poor contact in solenoid valve relay contacts and wiring harness, and poor ECM loop control.
