Air Flow Meter/Sensor: Testing and Inspection

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

Checking Air Flow Meter Resistance:

Air Flow Meter Resistance Chart:

3. If the readings are not as specified, replace the Air Flow Meter.
4. If readings are normal, remove the Air Flow Meter.
a. Disconnect air cleaner hose
b. Remove VSV (Idle Up)
c. Remove air cleaner cap with air flow meter

Removing Air Flow Meter:

d. Pry off the lock plate, and remove the four nuts, lock plate, air flow meter and gasket.


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.
