A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Put the engine in inspection mode (maintenance mode). Refer to INSPECTION MODE PROCEDURE .
5. Start the engine.
6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT Linear (Bank 1).
7. Check the engine speed while operating the camshaft timing oil control valve assembly using the Techstream.
   OK
   
   

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

   HINT: 

   • If the result is not acceptable, cool the engine (engine coolant temperature is 50°C (122°F) or less) and perform the Active Test again.
   • Test not possible with park (P) selected during charge control. Move shift lever to N to perform test.
   • If the DTCs are stored after the Active Test, clear the DTCs. Refer to DTC CHECK / CLEAR .

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Clear the DTCs. Refer to DTC CHECK / CLEAR .

   HINT: 

   • P0011 is output:

     Clear the DTC not using the Techstream.

   • P0012 is output:

     Clear the DTC using the Techstream.

5. Turn the power switch off and wait for at least 30 seconds.
6. Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
7. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
8. 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. Those foreign objects may then be captured by the oil filter.

A → See step   14 

1. Inspect the camshaft timing oil control valve assembly. Refer to INSPECTION .

NG → See step   10 

OK: Go to next step 

1. Inspect the camshaft timing gear assembly. Refer to DISASSEMBLY - Step 31 .

NG → See step   13 

OK: Go to next step 

1. Remove the oil control valve filter. Refer to DISASSEMBLY - Step 41 .

   OK

   Filter is not clogged.

NG → See step   11 

OK: Go to next step 

HINT: 

There are no marks on the cylinder head to match-up for the purpose of checking valve timing. Valve timing can only be inspected by lining up the colored plates on the timing chain with the marks on the pulleys. It may be necessary to remove and reinstall the chain to match-up the alignment marks. Refer to REASSEMBLY .
