The DELPHI Mass Air Flow (MAF) Sensor, part number AF10185-12B1, is a critical component for your vehicle's engine management system. It accurately measures the volume and density of air entering the engine, providing essential data to the Engine Control Unit (ECU). This precise measurement allows the ECU to calculate the correct amount of fuel to inject for optimal combustion. By ensuring the right air-fuel ratio, the MAF sensor contributes to improved fuel efficiency, reduced emissions, and consistent engine performance across various driving conditions. Replacing a faulty MAF sensor can resolve issues such as rough idling, poor acceleration, engine stalling, and illuminated check engine lights. Trust DELPHI for reliable and accurate airflow measurement to keep your engine running smoothly.
