DTC B1342

PCM malfunction

DETECTION 

CONDITION

• Malfunction in the PCM internal circuit.

POSSIBLE 

CAUSE

• PCM internal malfunction

STEP

INSPECTION

ACTION

1

VERIFY CURRENT STATUS OF MALFUNCTION

• Clear the DTC from the PCM memory using 

the M-MDS.

• Is same DTC present?

Yes

Replace the PCM, then go to the next step.

No

Go to the next step.

2

VERIFY AFTER REPAIR PROCEDURE

• Perform the “After Repair Procedure”.

 (See01-02-10 AFTER REPAIR 
PROCEDURE[L3 WITH TC].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.
 (See01-02-13 DTC TABLE[L3 WITH TC].)

No

Troubleshooting completed.

Revised 8/2006 (Ref. No. R087/06)

DTC P0011[L3 WITH TC]

id010239801600

Diagnostic procedure

DTC P0011

CMP Timing over-advanced

DETECTION 

CONDITION

• Actual valve timing is over-advanced by 17 ° (when the following conditions are met) from the target 

valve timing when the OCV is controlled at the maximum valve timing retard condition.

MONITORING CONDITION

— Engine speed is below 4,000 rpm.

— Engine coolant temperature is above 70— 110 

°C {158— 230 °F}.

Diagnostic support note

• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or 

in one drive cycle while the DTC for the same malfunction has been stored in the PCM.

•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive 

cycle.

• FREEZE FRAME DATA is available.

• DTCs are stored in the PCM memory.

POSSIBLE 

CAUSE

• OCV malfunction

• Spool valve in the OCV is stuck in the advance position.

• Variable valve timing actuator is stuck in the advance position.

• Loose timing chain or improper valve timing due to timing chain slippage

• PCM malfunction

STEP

INSPECTION

ACTION

1

VERIFY FREEZE FRAME DATA HAS BEEN 
RECORDED

• Has the FREEZE FRAME DATA been 

recorded?

Yes

Go to the next step.

No

Record FREEZE FRAME DATA on the repair order, then go 
to the next step.

2

VERIFY RELATED REPAIR INFORMATION 
AVAILABILITY

• Check for related Service Bulletins and/or on-

line repair information availability.

• Is any related repair information available?

Yes

Perform the 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

VERIFY TIMING CHAIN INSTALLATION

• Stop the engine.

• Remove the timing chain cover.

• Is the camshaft timing mark at the correct 

point?
 (See 01-10-10 TIMING CHAIN REMOVAL/
INSTALLATION[L3 WITH TC].)

Yes

Go to the next step.

No

Reinstall the timing chain, then go to Step 7.

4

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 7.

5

INSPECT STOPPER PIN MECHANISM

• Remove the timing chain.

• Inspect the stopper pin.

 (See 01-10-27 VARIABLE VALVE TIMING 
ACTUATOR INSPECTION[L3 WITH TC].)

• Is the stopper pin mechanism normal?

Yes

Go to the next step.

No

Replace the variable valve timing actuator, then go to Step 
7.

6

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 using the 

cleaning mode of the variable valve timing control 
function.

Go to the next step.

No

Replace the variable valve timing actuator, go to the next 
step.
