Airflow Meter
WARNING: This page is about a different car, the 1987 Toyota Cressida. However, it is still accessible from the selected car via links, so may be relevant.
Turn ignition off. Disconnect wiring connector from airflow meter. Using an ohmmeter, measure resistance between each terminal. See Fig 1. If resistance values do not meet specifications shown in table, replace airflow meter.
