Air Flow Meter/Sensor: Testing and Inspection

AIR FLOW METER








ON-VEHICLE INSPECTION

INSPECT RESISTANCE
1. Disconnect the air flow meter connector.








2. Using an ohmmeter, measure the resistance between each terminal.





If the resistance is not as specified, replace the air flow meter.

3. Reconnect the air flow meter connector.

OFF-VEHICLE INSPECTION

INSPECT RESISTANCE





Using an ohmmeter, measure the resistance between each terminal by moving the measuring plate.








NOTE: Resistance between terminals E2 and VS will change in accordance with the measuring plate opening. If the resistance is not as specified, replace the meter.
