Airflow Sensor

  1. Airflow sensor is located inside air cleaner assembly. Disconnect airflow sensor electrical connector. Using an ohmmeter, measure resistance between airflow sensor terminals No. 4 and 6 (non-turbo models) or No. 6 and 8 (turbo models). See Fig 1 .
  2. Resistance should be approximately 6000 ohms at 32°F (0°C), 2700 ohms at 68°F (20°C) and 400 ohms at 176°F (80°C). Note that as temperature increases resistance decreases.
  3. If airflow sensor resistance is not as specified, or if resistance remains unchanged, replace airflow sensor.
