CAMSHAFT OIL CONTROL VALVE INSPECTION

PROCEDURE

  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.

      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

        Measurement 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

        Table 1. Text in Illustration

        Component without harness connected

        (Camshaft Timing Oil Control Valve)

        Note:

        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.

        Tip:

        Accumulation of foreign matter causes subtle pressure leaks. The subtle pressure leaks will cause the camshaft to advance, and this will cause a DTC to be stored.
