CAMSHAFT OIL CONTROL VALVE INSPECTION

PROCEDURE


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

    Tech Tips

    Use the same procedure for the intake side and exhaust side.


    1. Check the resistance.


      1. B0045FOC03
        *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. B0045YWC01
        *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 the positive (+) lead from a battery to terminal 1 and the negative (-) lead to terminal 2, and check the movement of the spool valve.

        OK
        Tester Connection Condition Specified Condition
        1 - 2 Battery voltage is applied Valve moves in direction of left arrow shown in illustration
        Battery voltage is cut off Valve moves in direction of right arrow shown in illustration

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

        Note

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