Mass Air Flow Sensor

The Mass Air Flow Sensor measures the amount of air volume flowing into a car’s engine, and sends the Electronic Control Unit (ECU) a voltage that represents the airflow.
DENSO's improved air flow meter features a new sensing element bypass structure, which significantly reduces contamination of the sensing element for more accurate detection.


  • Glass film coated sensing elements reduces contamination
    and improves reliability
  • Platinum wire sensing element responds quickly to changes in air flow
  • DENSO's innovative designs reduce the size and weight
