The Delphi Mass Air Flow (MAF) Sensor is engineered to precisely measure the amount of air entering the engine's intake manifold. This critical data is then sent to the engine control unit (ECU) to calculate the correct amount of fuel to inject, ensuring optimal combustion. By providing accurate airflow readings, this sensor helps to improve engine responsiveness, reduce fuel consumption, and minimize harmful emissions. A malfunctioning MAF sensor can lead to poor acceleration, rough idling, increased fuel usage, and check engine lights. Delphi is a trusted name in automotive components, known for producing high-quality parts that meet or exceed original equipment specifications. This AF10779-12B1 sensor is designed for reliable and long-lasting performance in your vehicle.
