Component Test

1. Disconnect Air Flow Meter connector.
2. Using an Ohmmeter, measure the resistance between each terminal. (Refer to chart)

Measuring Air Flow Meter Resistance:

3. If the readings are not as specified, replace the Air Flow Meter.
4. If readings are normal, remove the Air Flow Meter.
5. Using an Ohmmeter, measure the resistance between the terminals while moving the flap (measuring plate).

7. If readings are not as specified, replace the Air Flow Meter.
8. Check that flap does not bind and moves smoothly in its travel.
9. Reinstall Air Flow Meter and reattach the connector.
