The DELPHI Mass Air Flow (MAF) Sensor, part number AF10287-12B1, 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 amount of fuel to inject for optimal combustion. By accurately monitoring airflow, this sensor plays a vital role in maintaining your vehicle's performance, fuel economy, and emissions control. A malfunctioning MAF sensor can lead to various issues, including rough idling, poor acceleration, increased fuel consumption, and illuminated check engine lights. This DELPHI MAF sensor is designed as a direct replacement for your original equipment, ensuring a straightforward installation process. Trust DELPHI for reliable and high-quality engine management components that keep your vehicle running smoothly.
