The Mass Air Flow (MAF) sensor plays a critical role in your vehicle's engine management system. By precisely measuring the volume and density of air entering the intake manifold, it provides crucial data to the engine control unit (ECU). This data allows the ECU to calculate the correct amount of fuel to inject for optimal combustion. A malfunctioning MAF sensor can lead to various drivability issues, including poor acceleration, rough idling, increased fuel consumption, and illuminated check engine lights. This DELPHI Mass Air Flow Sensor, part number AF10301-12B1, is engineered to meet or exceed original equipment specifications. It is designed for a direct fit, ensuring a straightforward installation process without the need for modifications. Trust DELPHI for reliable and accurate air flow measurement to keep your engine running smoothly.
