      Measure the resistance of the oil control valve.

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

        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.
