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. (See DTC CONFIRMATION PROCEDURE.) • Is the same DTC present? | Yes | Go to the next step.
No | Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING.)
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. (See VARIABLE VALVE TIMING ACTUATOR INSPECTION [ZJ, ZY].) • 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. (See PCM REMOVAL/INSTALLATION.)
No | Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE.) • Are any DTCs present? | Yes | Go to the applicable DTC troubleshooting. (See DTC TABLE.)
No | Troubleshooting completed.
