This Mass Air Flow (MAF) sensor from DELPHI, part number AF10280-12B1, is designed to accurately measure the volume and density of air entering the engine's intake system. By providing precise air intake data to the engine control unit (ECU), this sensor ensures the correct amount of fuel is injected for combustion. This leads to improved engine efficiency, smoother idling, and better throttle response. Regular replacement of a faulty MAF sensor can prevent issues such as poor fuel economy, engine misfires, and check engine lights. Trust DELPHI for reliable and accurate airflow measurement.
