DTC P0011 |
CMP Timing over-advanced |
|---|---|
|
DETECTION CONDITION
|
• Actual valve timing is over-advanced by 17 ° (when the following conditions are met) from the target valve timing when the OCV is controlled at the maximum valve timing retard condition.
MONITORING CONDITION
Diagnostic support note
• This is a continuous monitor (CCM).
• The 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.
• DTCs are stored in the PCM memory.
|
|
POSSIBLE CAUSE
|
• Loose timing chain or improper valve timing due to timing chain slippage
• OCV malfunction
• Spool valve in the OCV is stuck in the advance position.
• Variable valve timing actuator is stuck in the advance position.
• PCM malfunction
