Camshaft Timing Oil Control Valve Assembly: Inspection

INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
1. Resistance inspection.
  1. Using an ohmmeter, measure the resistance between the terminals.
  Resistance: 6.9 to 7.9 Ω at 20°C (68°F)
2. Movement inspection.
  1. Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.
  NOTE: Confirm the valve moves freely and does not stick in any position.
  
  HINT:
  
  Bad returning of the valve by catching foreign objects causes subtle pressure leak. The subtle pressure leaks will cause the cam to advance, and this condition will set a DTC.
