The DELPHI Mass Air Flow Sensor, part number AF10626-12B1, is engineered to precisely measure the amount of air entering your engine's intake manifold. This critical data is then sent to the engine control unit (ECU) to help determine the correct fuel injection rate. By ensuring the ECU receives accurate air flow readings, this sensor contributes to improved fuel efficiency, smoother engine operation, and reduced emissions. A malfunctioning mass air flow sensor can lead to poor acceleration, rough idling, and increased fuel consumption. This sensor is designed for reliable performance and durability, meeting the high standards expected from DELPHI. It is a direct fit for compatible vehicles, simplifying the replacement process.
