Air Flow Meter
- Connect ohmmeter across pins 33 and 26 in connectors. Resistance should be 280-400 ohms. If not, check resistance at meter. If not correct, repair harness or replace air flow meter. See Figure.
- Connect ohmmeter across pins 33 and 31 at connector. Resistance should measure any value between infinity and zero. If not, check resistance at meter. If okay at meter, repair harness. If not, replace air flow meter.

- Connect 1 lead to ground and the other lead of ohmmeter to connector pin 26, then 31, then 33. Infinite resistance should be shown in all cases. If not, repeat check at connector pins or air flow meter. Repair harness or replace meter as necessary.
- Operate air flow meter flap by hand to ensure it moves smoothly without binding. If okay, meter is functioning properly. If not, replace air flow meter.
