DTC P0011:00 OR P0012:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE
| Description |
Electric variable valve timing control system:
- P0011:00: Over-advanced
- P0012:00: Over-retarded
|
| Detection condition |
Determination conditions |
- P0011:00: For the advance amount from the maximum intake valve retard position, a condition in which the actual advance amount is larger than the target value continues for a specified period of time.
|
- P0012:00: For the advance amount from the maximum intake valve retard position, a condition in which the actual advance amount is smaller than the target value continues for a specified period of time.
|
| Preconditions |
- Battery voltage: above 11 V
- Engine speed: 5, 000 rpm or less
- Engine coolant temperature: 20 °C {68 °F} or more
