DTC P0011 [L3]


DTC P0011	CMP - Timing over-advanced
DETECTION CONDITION	• Actual valve timing is over-advanced by 30 deg. from target valve timing when the OCV is controlled in 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 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


STEP	INSPECTION		ACTION
1	PERFORM DTC CONFIRMATION PROCEDURE • Perform the DTC CONFIRMATION PROCEDURE. (See DTC CONFIRMATION PROCEDURE [LF, L3].) • Is the same DTC present?	Yes	Go to the next step.
1		No	Intermittent concern exists. Go to the INTERMITTENT CONCERN TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [LF, L3].)
2	INSPECT OCV FOR MALFUNCTION • Start the engine. • Increase 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.
2		No	Replace the OCV, then go to Step 5.
3	INSPECT STOPPER PIN MECHANISM • Remove the timing belt. • Inspect the stopper pin. (See VARIABLE VALVE TIMING ACTUATOR INSPECTION [L3].) • Is the stopper pin mechanism normal?	Yes	Go to the next step.
3		No	Replace the variable valve timing actuator, then go to Step 5.
4	INSPECT ROTOR POSITION • Remove 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 the variable valve timing control function. Go to the next step.
4		No	Replace the variable valve timing actuator, go to the next step.
5	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. • Perform the KOER self-test. (See KOEO/KOER SELF-TEST [LF, L3].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [LF, L3].)
5		No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [LF, L3].) • Are any DTCs present?	Yes	Go to the applicable DTC troubleshooting. (See DTC TABLE [LF, L3].)
6		No	Troubleshooting completed.
