The DELPHI Mass Air Flow (MAF) Sensor, part number AF10773-12B1, plays a critical role in your vehicle's engine management system. It precisely measures the volume and density of air entering the engine, providing essential data to the Engine Control Unit (ECU). By accurately reporting airflow, the ECU can then calculate the correct amount of fuel to inject for optimal combustion. This leads to improved engine performance, better fuel economy, and reduced emissions. A malfunctioning MAF sensor can cause a range of issues, including rough idling, poor acceleration, increased fuel consumption, and check engine lights. This DELPHI MAF sensor is engineered to meet or exceed original equipment specifications, ensuring reliable and consistent performance. Trust DELPHI for quality components that keep your engine running smoothly and efficiently.
