DTC P0011

CMP Timing over-advanced

DETECTION CONDITION

• The actual valve timing is over-advanced from the target valve timing when the OCV is controlled within the maximum valve timing retard condition.
Diagnostic support note
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycles.
• The PENDING CODE is available if the PCM detects the above malfunction condition.
• The FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• OCV malfunction
• The spool valve in the OCV is stuck in the advance position.
• The variable valve timing actuator is stuck in the advance position.
• Loose timing belt or improper valve timing due to timing belt slippage
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
PERFORM DTC CONFIRMATION PROCEDURE
• Perform the DTC CONFIRMATION PROCEDURE.
• Is the same DTC present?
Yes
Go to the next step.
No
Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure.
2
VERIFY RELATED PENDING CODE OR STORED DTCS
• Is DTC P1384 present?
Yes
Go to the DTC P1384 troubleshooting procedure.
(See DTC P1384.)
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 belt.
• 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.
• The intermittent concern might be removed during the cleaning mode of 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.
• Turn the ignition switch to the ON position (Engine off).
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Start the engine.
• Access RPM PID using the WDS or equivalent.
• Turn off all electrical loads.
• Increase and keep the engine speed at 4,500 rpm or more for 5 s.
• Is the PENDING CODE the same as the 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 troubleshooting.
(See DTC TABLE.)
No
Troubleshooting completed.
