Airflow Meter Testing

Remove rubber cover from electrical connector on airflow meter. Leave connector connected. Connect volt/ohmmeter between terminals and record readings. See AIRFLOW METER SPECIFICATIONS table. If readings are not to specifications, check electrical wiring. If wiring is okay, replace airflow sensor.

NOTE: DO NOT start engine unless specified. Place the ignition switch in the OFF or ON position as indicated.
