The DELPHI AF10403-12B1 Mass Air Flow (MAF) sensor is engineered to provide accurate air intake measurements. This data is vital for the engine control unit (ECU) to precisely calculate the amount of fuel to inject, ensuring efficient combustion and optimal engine performance. Proper functioning of the MAF sensor contributes to better fuel economy and reduced emissions. A failing sensor can lead to various drivability issues, including rough idling, hesitation, stalling, and illuminated check engine lights. This DELPHI sensor is designed to meet or exceed original equipment specifications for reliable operation. Installation of this sensor helps restore proper engine function and can resolve common performance problems associated with a faulty MAF.
