1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

  1. Resistance inspection.

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

      Standard resistance:
      6.9 to 7.9 Ω at 20°C (68°F)
      If necessary, replace the camshaft timing oil control valve assembly.
  1. Movement inspection.Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check the movement of the valve.NOTICE: Confirm that the valve moves freely and does not stick in any position.If necessary, replace the camshaft timing oil control valve assembly.HINT: Accumulation of foreign objects causes subtle pressure leaks. The subtle pressure leaks will cause the camshaft to advance, and this will cause a DTC to be set. Camry
