Air Flow Meter/Sensor: Testing and Inspection

Air Flow Meter Test:

1. Pull the rubber insulator back from the air flow meter connector.
2. Turn the ignition switch ON.
3. Using a volt meter, check voltage between terminal B and ground.
Voltage should be approximately 0.8 VDC.
4. Start and warm the engine to operating temperature and then idle it.
5. Using a volt meter, check voltage between terminal B and ground.
Voltage should be approximately 0.8 - 1.5 VDC.
If the meter fails the above test, check the "hot wire" for dust or damage and replace the meter if necessary.
