1 Answers
Check if the engine oil is severely dirty, and replace it if necessary. If the issue persists or there are other faults, consult a professional technician. Regularly ensure timely replacement of engine oil and oil filters. The causes of P0012 timing delay are as follows: 1. Low gasoline octane rating or engine misfiring causing camshaft lag, altering the position sensor signal data. 2. OCV valve malfunction: Possibly due to the OCV valve sticking, leading to failure of the intake valve oil control valve. 3. Oil control valve failure: Sticking of the oil pressure control valve OCV. 4. Abnormal current in CVVT control circuit: Mechanical jamming of the CVVT actuator gear. 5. Oil pump wear: Sticking of the oil pump pressure regulator valve or system blockage.
