CAMSHAFT OIL CONTROL VALVE INSPECTION

PROCEDURE


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    1. A001RC4C06
      *a

      Component without harness connected

      (Camshaft Timing Oil Control Valve Assembly)

      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 camshaft timing oil control valve assembly.

    2. Check the operation.


      1. A001PROC04
        *a

        Component without harness connected

        (Camshaft Timing Oil Control Valve Assembly)
        *b When Battery Voltage Applied
        *c When Battery Voltage Cut Off
        *d Spool Valve

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

        OK
        Condition Specified Condition
        Battery voltage applied Valve moves in left arrow direction shown in illustration
        Battery voltage cut off Valve moves in right arrow direction shown in illustration

        Note

        Confirm that the valve moves freely and does not stick in any position.

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

        Tech Tips

        Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks will cause the camshaft to advance or retard, and this will cause a DTC to be stored.
