Reasons for P0012 Camshaft Position Timing Retardation

[OAurora]

p0012 camshaft timing retardation reasons are as follows: 1. Low gasoline octane rating or engine misfire causing engine hesitation leads to camshaft delay, altering the position sensor signal data. 2. Oil pressure control valve (OCV) sticking. 3. CVVT actuator gear mechanical seizure. 4. Oil pump wear, oil pump pressure regulator valve sticking, or system blockage. 5. Incorrect timing belt or chain alignment. 6. Abnormal CVVT control circuit current, poor electromagnetic valve relay contacts and wiring harness connections, and faulty ECM loop control.
