CAMSHAFT OIL CONTROL VALVE INSPECTION

PROCEDURE


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    1. Inspect 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 camshaft timing oil control valve assembly.

    2. Check the operation.

        Component without harness connected

        (Camshaft Timing Oil Control Valve Assembly)
        *b When Applied
        *c When Cut Off

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

        OK
        Condition Specified Condition
        Auxiliary battery voltage is applied Valve moves in direction of left arrow shown in illustration
        Auxiliary battery voltage is cut off Valve moves in direction of right arrow shown in illustration

        Note

        Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks in the intake side camshaft timing oil control valve assembly will cause the intake camshaft to advance. 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.

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