The DELPHI AF10385-12B1 Mass Air Flow (MAF) sensor is a critical component for modern engine management systems. It accurately measures the volume and density of air entering the engine, providing vital data to the Engine Control Unit (ECU). By precisely knowing the incoming air mass, the ECU can calculate the exact amount of fuel to inject, leading to improved fuel efficiency, reduced emissions, and optimal engine performance. A faulty MAF sensor can cause rough idling, poor acceleration, increased fuel consumption, and check engine lights. This DELPHI MAF sensor is designed to meet or exceed original equipment specifications, ensuring reliable and accurate readings for your vehicle's needs.
