CAMSHAFT OIL CONTROL VALVE INSPECTION

PROCEDURE


  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 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.

        *b When Applied
        *c When Cut Off
        *d Valve

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

        OK
        Condition Specified Condition
        Auxiliary battery voltage is applied Valve moves in left arrow direction shown in illustration
        Auxiliary battery voltage is 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 necessary, 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.
