The DELPHI Mass Air Flow (MAF) Sensor, part number AF10250-12B1, is engineered to accurately measure the volume and density of air entering your vehicle's engine. This precise measurement is vital for the engine control unit (ECU) to calculate the correct amount of fuel to inject, ensuring efficient combustion. A properly functioning MAF sensor contributes to improved fuel economy, smoother engine operation, and reduced emissions. This sensor is designed to meet or exceed original equipment specifications, providing reliable performance and durability. Replacing a faulty MAF sensor can resolve issues such as rough idling, poor acceleration, stalling, and check engine lights.
