Camshaft Oil Control Valve -- Inspection



1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

  1. Check the resistance.

    1. 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
      If the result is not as specified, replace the oil control valve assembly.

  1. Check the operation.

    1. Connect the battery positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.

      OK:
      Condition
      		Specified Condition
      Battery positive (+) voltage is applied
      		Valve moves in left arrow direction shown in illustration
      Battery positive (+) voltage is cut off
      		Valve moves in right arrow direction shown in illustration

      NOTICE:
      Confirm that the valve moves freely and does not stick in any position.
      If the result is not as specified, replace the oil control valve assembly.
      HINT:
      Accumulation of foreign objects causes subtle pressure leaks. The subtle pressure leaks will cause the camshaft to advance, and this will cause a DTC to be set.
