DTC P0012: Notes
DTC P0012 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0012 |
CMP timing over-retarded (RH) |
| DETECTION CONDITION |
- The actual valve timing is over-retarded by 10°
from the target valve timing for 4 s
when the OCV system control is within the feedback range.
MONITORING CONDITIONS
- Engine coolant temperature is above 63 °C {145 °F}
Diagnostic support note
- This is a continuous monitor (CCM).
- MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- DTC is stored in PCM memory.

| POSSIBLE CAUSE |
- Low engine oil pressure
- Oil control valve malfunction
- Loose timing chain or improper valve timing
- Spool valve in OCV (RH) is stuck in retard position
- The following oil runners are clogged or have leakage:
- Between oil pressure switch and OCV (RH)
- Between OCV (RH) and variable valve timing actuator (RH)
- In variable valve timing actuator (RH)
- Variable valve timing actuator (RH) is stuck in retard position
- PCM malfunction
