2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine / Trouble Codes.
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.

B → See step   10 

A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Start the engine.
3. Turn the Techstream on.
4. Turn the A/C switch on.
5. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Linear (Bank 1).
6. Check the engine speed while operating the camshaft timing oil control valve assembly (for intake camshaft) using the Techstream.

   Result

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

NG → See step   4 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Clear the DTCs, refer to DTC CHECK / CLEAR .
5. Turn the ignition switch off.
6. Turn the ignition switch to ON and turn the Techstream on.
7. Start the engine.
8. Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
9. Enter the following menus: Powertrain / Engine / Trouble Codes / Pending.
10. 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 the 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.
