  2. Using ohmmeter, measure resistance between specified terminals. See AIRFLOW METER RESISTANCE SPECIFICATIONS  table. Replace airflow meter if resistance is not within specification.
  3. To check airflow meter operation, ensure electrical connector is installed on airflow meter. Connect voltmeter leads to proper terminals on airflow meter with electrical connector installed. See Figure.
  4. Turn ignition on. Apply air into airflow meter and note voltage reading. See Figure. While air is being applied, voltage reading should fluctuate. Replace airflow meter if voltage does not fluctuate. Remove voltmeter.
