Airflow Meter

  1. Turn ignition switch to ON position. Without disconnecting airflow meter connector, move connector seal for access to terminals. Turn ignition on. Using a DVOM with a minimum 10-megohm input impedance, backprobe between White and Red wire terminals of connector.
  2. If battery voltage is present, go to next step. If battery voltage is not present, check continuity of White and Red wire circuits between ECM and airflow meter connector.
  3. Measure voltage between Black and Red wire terminals of airflow meter connector. If voltage is not 0.2-0.8 volt, check continuity of Black and Red wire circuits between ECM and airflow meter connector.
  4. Start engine. Airflow meter voltage signal should increase as engine RPM increases. If airflow meter does not test as described, check airflow meter connections. If connections are okay, replace airflow meter.
