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

   HINT: 

   • Refer to "Data List / Active Test" [VVT OCV Duty #1 and VVT Change Angle #1]. Refer to DATA LIST / ACTIVE TEST [08/2013 - ] .
   • 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 the shift lever in P during charge control. Move the shift lever to N to perform test.
   • If the DTCs are stored after the Active Test, clear the DTCs. Refer to DTC CHECK / CLEAR [08/2013 - ] .

    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.
