The DELPHI Mass Air Flow (MAF) Sensor, part number AF10264-12B1, is engineered to precisely measure the volume and density of air entering the engine. This critical data is then relayed to the engine control unit (ECU) to determine the correct amount of fuel to inject for efficient combustion. Proper functioning of the MAF sensor is vital for maintaining optimal engine performance, fuel economy, and emissions control. A faulty sensor can lead to various drivability issues, including rough idling, hesitation, stalling, and reduced power. This DELPHI sensor is designed to meet or exceed original equipment specifications, providing a reliable replacement for your vehicle. Installation of this sensor should be performed by a qualified technician. Ensure compatibility with your vehicle's make and model before purchase. Regular maintenance and inspection of the MAF sensor can help prevent potential engine problems and ensure your vehicle runs smoothly.
