Camshaft Timing Oil Control Valve Assembly

  1. Inspect camshaft timing oil control valve assembly



​

1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
  1. Check the resistance.Using an ohmmeter, measure the resistance between the terminals.Resistance:Tester ConnectionSpecified Condition1 (+B) - 2 (GND)6.9 to 7.9 Ω at 20°C (68°F)If the result is not as specified, replace the camshaft timing oil control valve. 4Runner

  2. Check the resistance.

    1. Using an ohmmeter, measure the resistance between the terminals.

      Resistance:
      Tester Connection
      		Specified Condition
      1 (+B) - 2 (GND)
      		6.9 to 7.9 Ω at 20°C (68°F)
      If the result is not as specified, replace the camshaft timing oil control valve.
  1. Check the operation.Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check that the valve operates.NOTICE: Check that the spool valve is not stuck.HINT: The spool valve may not return if foreign objects are caught in it. This may cause subtle pressure leakage to the advance side, and a DTC may, be set. 4Runner

  2. Check the operation.

    1. Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check that the valve operates.

      NOTICE:
