CAMSHAFT OIL CONTROL VALVE INSPECTION


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Specified Condition
      1 - 2 6.9 to 7.9 Ω at 20°C (68°F)

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

      *1 Spool Valve
      *2 Battery

      Check the operation.


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

        OK
        Condition Specified Condition
        Battery voltage is applied Valve moves in black arrow direction shown in illustration
        Battery voltage is not applied Valve moves in white arrow direction shown in illustration

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

        Note

        Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks in the intake side oil control valve will cause the intake camshaft to advance. Minor pressure leaks in the exhaust side oil control valve will cause the exhaust camshaft to retard. The inappropriate camshaft timing that results from these leaks will cause a DTC to be set.
