DESCRIPTION

WIRING DIAGRAM

INSPECTION PROCEDURE

HINT:

DTC P0011 or P0012 may be stored when foreign objects in the engine oil are caught in some parts of the system. The DTC will remain set even if the system returns to normal after a short time. Those foreign objects may then be captured by the oil filter.

HINT:

Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

1. Connect the intelligent tester to the DLC3.

2. Turn the ignition switch to ON.

3. Turn the tester on.

4. Enter the following menus: Powertrain / Engine and ECT / DTC.

5. Read the DTCs.
   

   Result:

   
   

   Result	Proceed to
   DTC P0011 or P0012 is output	A
   DTC P0011 or P0012 and other DTCs are output	B

   HINT:

   If any DTCs other than P0011 or P0012 are output, troubleshoot those DTCs first.

A

1. Connect the intelligent tester to the DLC3.

2. Start the engine.

3. Turn the tester on.

4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Linear (Bank 1).

5. Check the engine speed while operating the camshaft timing oil control valve assembly using the tester.
   

   OK:

   
   

   Tester Operation	Specified Condition
   0%	Normal engine speed
   100%	Engine idles roughly or stalls

NG	Go to step 4

OK

1. Connect the intelligent tester to the DLC3.

2. Turn the ignition switch to ON.

3. Turn the tester on.

4. Clear the DTCs (Click here).

5. Start the engine and warm it up.

6. Drive the vehicle at approximately 60 km/h (37 mph) for 10 minutes or more.

   CAUTION:

   When performing the confirmation driving pattern, obey all speed limits and traffic laws.

7. Idle the engine for 3 minutes or more.

8. Enter the following menus: Powertrain / Engine and ECT / DTC.

9. Read the pending DTCs.

   HINT:

   1. If a pending DTC is output, the system is malfunctioning.
      
   2. If a pending DTC is not output, perform the following procedure.
      

10. Repeat the pattern of accelerating the vehicle from rest to approximately 60 km/h (37 mph) and then decelerating the vehicle 10 to 15 times.

    CAUTION:

    When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    HINT:

    Depress the accelerator pedal by a large amount.

11. Idle the engine for 3 minutes or more.

12. Enter the following menus: Powertrain / Engine and ECT / DTC.

13. Read the pending DTCs.
    

    Result:

    
    

    Result	Proceed to
    DTC is not output	A
    DTC P0011 or P0012 is output	B

    HINT:

    DTC P0011 or P0012 may be stored when foreign objects in engine oil are caught in some parts of the system. The DTC will remain stored even if the system returns to normal after a short time. These foreign objects may then be captured by the oil filter.

1. Remove the camshaft timing oil control valve assembly.

2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   1 - 2	20°C (68°F)	6.9 to 7.9 Ω

   *1	Component without harness connected (Camshaft Timing Oil Control Valve Assembly)

3. Connect the positive (+) battery terminal to terminal 1 and connect the negative (-) battery terminal to terminal 2. Check the valve operation.

   OK:

   Valve moves quickly.
   

4. Reinstall the camshaft timing oil control valve assembly.

OK

1. Remove the cylinder head cover.

2. Turn the crankshaft pulley, then align its groove with the timing mark "0" on the timing chain cover.

3. Check that the point marks on the camshaft timing gears are aligned with the timing chain cover surface as shown in the illustration.
   If not, turn the crankshaft 1 revolution (360°), then align the marks as above.

   OK:

   Alignment marks on camshaft timing gears are aligned as shown in the illustration.
