DTC P0011

CMP timing over-advanced

DETECTION CONDITION

• The actual valve timing is over-advanced by 17 ° from the target valve timing for specified period when the oil control valve (OCV) is controlled in the maximum valve timing retard condition.
Monitoring condition
- Engine speed is below 4,000 rpm
- Engine coolant temperature is 70-110 °C {158-230 °F}
Diagnostic support note
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition during first drive cycle.
• PENDING CODE is available if the PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• Are any DTCs is stored in the PCM memory.

POSSIBLE CAUSE

• OCV malfunction
• Spool valve in OCV is stuck in advanced position
• Variable valve timing actuator is stuck in advanced position
• Loose timing chain or improper valve timing due to timing chain slippage
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Verify related Service Information availability.
• Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service information.
If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT OCV FOR MALFUNCTION
• Start the engine.
• Increase the engine speed.
• Stop the engine.
• Remove the OCV.
• Inspect the position of the spool valve in the OCV.
• Is the spool valve located at the valve retard position?
Yes
Go to the next step.
No
Replace the OCV, then go to Step 6.
4
INSPECT STOPPER PIN MECHANISM
• Remove the timing chain.
• Inspect the stopper pin.
• Is the stopper pin mechanism normal?
Yes
Go to the next step.
No
Replace the variable valve timing actuator, then go to Step 6.
5
INSPECT ROTOR POSITION
• Remove the variable valve timing actuator.
• Is the rotor position at the maximum valve timing retard?
Yes
VARIABLE VALVE TIMING MECHANISM IS NORMAL
Note
• This DTC is detected as an intermittent concern.
• An intermittent concern might be removed using the cleaning mode of the variable valve timing control function.
Go to the next step.
No
Replace the variable valve timing actuator, go to the next step.
6
VERIFY TROUBLESHOOTING OF DTC P0011 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Turn the ignition switch off.
• Start the engine and warm it up completely.
• Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
7
VERIFY AFTER REPAIR PROCEDURE
• Perform the "AFTER REPAIR PROCEDURE".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
