DTC P0011 [L8, LF]

id0102b1801600

DTC P0011

CMP timing over-advanced
DETECTION CONDITION
•  The actual valve timing is over-advanced by 15 ° from the target valve timing for specified period when the OCV is controlled in the maximum valve timing retard condition.
MONITORING CONDITIONS
―  Engine coolant temperature: above 63 °C {145.4 °F}
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA (Mode 2/Mode 12) is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  OCV malfunction (spool valve in OCV is stuck in advanced position)
•  Stopper pin mechanism malfunction
•  Variable valve timing actuator malfunction (stuck in advanced position)
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE 12) HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA (Mode 12) been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 12) on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE 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
•  Remove the OCV.
•  Inspect the position of the spool valve in the OCV.
•  Is the spool valve located at the valve advanced position?
Yes
Replace the OCV, then go to Step 6.
(See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [L8, LF].)
No
Go to the next step.
4
INSPECT STOPPER PIN MECHANISM
•  Remove the timing chain.
•  Inspect the stopper pin.
•  Is there any malfunction?
Yes
Replace the variable valve timing actuator, then go to Step 6.
(See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [LF].)
No
Go to the next step.
5
INSPECT ROTOR POSITION
•  Remove the variable valve timing actuator.
•  Is the rotor at the maximum valve timing advanced position?
Yes
Replace the variable valve timing actuator, go to the next step.
(See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [LF].)
No
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.
6
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Turn the ignition switch off.
•  Start the engine and warm it up completely.
•  Perform the KOER self test.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [L8, LF].)
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 [L8, LF].)
No
DTC troubleshooting completed.
