BSE Original 221044M Mass Air Flow Sensor Remanufactured

The BSE Original 221044M is a remanufactured mass air flow (MAF) sensor designed as a direct-fit replacement for compatible Volvo applications. The mass air flow sensor measures the volume and density of air entering the engine, providing critical data to the engine control module for precise fuel delivery and ignition timing. A failing MAF sensor can cause poor fuel economy, rough idle, hesitation, and illuminated check engine lights, making timely replacement essential for restoring proper engine performance.

Key Features:

• Remanufactured unit — includes housing
• Plastic housing construction
• Bolt-on mounting for straightforward installation
• Single rectangular female connector with 5 male blade terminals
• No ECU flash or programming required after installation
• Sensor only — dedicated mass air flow function

This MAF sensor is engineered to restore accurate air measurement and smooth engine operation. Fits select 1999–2009 Volvo models.
