DTC P0011 [ZJ, Z6]

B3E010200001W01

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 in the first drive cycle.
• PENDING CODE is available if the PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE | • OCV malfunction • Spool valve in OCV is stuck in advance position. • Variable valve timing actuator is stuck in advance 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 HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service repair information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to the available repair 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.
(See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [ZJ, Z6].)
• Inspect the position of the spool valve in the OCV.
(See OIL CONTROL VALVE (OCV) INSPECTION [ZJ, Z6].)
• Is the spool valve located at valve retard position?

Yes

Go to the next step.

No | Replace the OCV, then go to Step 6. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [ZJ, Z6].)
4 | INSPECT STOPPER PIN MECHANISM • Inspect the stopper pin. (See VARIABLE VALVE TIMING ACTUATOR INSPECTION [ZJ, Z6].) • Is the stopper pin mechanism normal? | Yes | Go to the next step.
No | Replace the variable valve timing actuator, then go to Step 6. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [ZJ, Z6].)

5

INSPECT ROTOR POSITION
• Remove the variable valve timing actuator.
(See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [ZJ, Z6].)
• Is the rotor position at maximum valve timing retard?

Yes

VARIABLE VALVE TIMING MECHANISM IS NORMAL

  Note

  • This DTC is detected by intermittent concern.
  • Intermittent concern might be removed by 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. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [ZJ, Z6].)

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 roads.
• Increase and keep the engine speed at 4,500 rpm or more for 5 s.
• Is the same DTC present?

Yes

Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [ZJ, Z6].)

No | Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [ZJ, Z6].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [ZJ, Z6].)
No | DTC troubleshooting completed.
