id0102b6801600
DTC P0011 |
CMP timing over-advanced |
---|---|
DETECTION CONDITION
|
• The actual valve timing is over-advanced by 15 ° (when the following conditions are met) from the target valve timing when the OCV is controlled in 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 during the first drive cycle.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.
|
POSSIBLE CAUSE
|
• Oil control valve (OCV) malfunction
• Spool valve in OCV is stuck in advance position
• Variable valve timing actuator is stuck in advance position
• Loose timing chain or improper valve timing due to timing chain slippage
• PCM malfunction
