2. Remove the intake air connector.
3. Disconnect the oil control valve connector.
4. Using an ohmmeter, measure the resistance between the terminals.
  Standard Resistance: 6.9 to 7.9 Ω at 20°C (68°F)
  
  If the resistance is not as specified, replace the valve.
5. Reconnect the oil control valve connector.
