  1. Inspect camshaft timing oil control valve assembly



1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


Check the resistance.Measure the resistance between the terminals.Standard resistance:6.9 to 7.9 Ω at 20 °C (68°F)If the result is not as specified, replace the oil control valve assembly. Yaris
  1. Check the resistance.

    1. Measure the resistance between the terminals.

      Standard resistance:
      6.9 to 7.9 Ω at 20 °C (68°F)

  1. Check the operation.Connect the positive (+) battery lead to terminal 1 and the negative (-) lead to terminal 2, and check the movement of the valve.Standard:ConditionSpecified ConditionBattery positive (+) voltage appliedValve moves in left arrow direction shown in the illustrationBattery positive (+) voltage cut offValve moves in right arrow direction shown in the illustrationIf the result is not as specified, replace the oil control valve.NOTICE: If the valve cannot return properly because of foreign matter intrusion, a small amount of leakage in the advanced direction may occur and a DTC may be output.
