DTC P0012:00: Notes
DTC P0012:00 (L3 WITH TC) DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0012:00 |
CMP Timing over-retarded |
| DETECTION CONDITION |
- Actual valve timing is over-retarded by 10
° (when the following conditions are met) from the target valve timing for 5 s
when the OCV system control is within the feed-back range.
MONITORING CONDITIONS
- Engine speed: below 4, 00 RPM
- Engine coolant temperature: 70-110°C {158-230°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 (Mode 2)/Snapshot data is available.
- DTCs are stored in the PCM memory.
|
| POSSIBLE CAUSE |
- Low engine oil pressure
- Loose timing chain or improper valve timing due to timing chain slippage
- OCV malfunction
- Spool valve in OCV is stuck in the retard position.
- Variable valve timing actuator is stuck in the retard position.
- Following oil runners are clogged or have leakage.
- Between oil pressure switch and OCV
- Between OCV and variable valve timing actuator
- In variable valve timing actuator
- PCM malfunction
