   RESULT
   
   

   Result	Proceed to
   P0011 or P0012 is output	A
   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: Go to next step 

1. Connect the Techstream to the DLC3.
2. Start the engine.
3. Turn the Techstream on.
4. Warm up the engine.
5. Turn the A/C on.
6. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Linear (Bank 1).

   OK

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

   HINT:

1. Remove the cylinder head cover.
2. Turn the crankshaft pulley and align its groove with the "0" timing mark of the timing chain cover.
3. Check that the timing marks of the camshaft timing gear and camshaft timing exhaust gear are at the positions shown in the illustration.

   HINT: 

   If the timing marks are not as shown, turn the crankshaft one revolution clockwise.

   OK

   Timing marks on camshaft timing gear and camshaft timing exhaust gear are aligned as shown in the illustration.

NG → See step   11 

OK: Go to next step 

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

NG → See step   12 

OK: Go to next step 

1. Remove the oil control valve filter. Refer to DISASSEMBLY .
2. Check that the filter is not clogged.

   OK

   Filter is not clogged.

NG → CLEAN OR REPLACE OIL CONTROL VALVE FILTER 

OK: Go to next step 

1. Replace the camshaft timing gear assembly. Refer to REMOVAL .

NEXT: Go to next step 

1. Perform the Confirmation Driving Pattern.

   OK

   No pending DTC is output and All Readiness is NORMAL.

   HINT: 

   DTC P0011 or P0012 is stored when foreign objects in the engine oil are caught in some parts of the system. These codes will remain stored even if the system returns to normal after a short time. These foreign objects are then captured by the oil filter, thus eliminating the source of the problem.
