SFI System: Inspection

INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSY
1. Using an ohmmeter, measure the resistance between the terminals.
  Resistance: 6.9 - 7.9 +/- at 20°C (68°F)
2. Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.
