Delphi AF10441 Mass Air Flow Sensor MAF Sensor

The Delphi AF10441 is a direct-fit replacement Mass Air Flow (MAF) sensor — also known as an air meter or air flow sensor — engineered to restore accurate air measurement and proper engine management. Built to OE standards by one of the original equipment manufacturers of MAF sensors, this unit delivers reliable performance from day one.

The MAF sensor continuously monitors the volume and velocity of air entering the engine's intake system, feeding that data directly to the Engine Control Module (ECM). The ECM uses this signal to precisely control fuel injection timing and quantity, maintaining the ideal air-fuel ratio for optimal combustion.

Key Features:

• All-new construction — built with calibrated all-new components; never remanufactured or refurbished
• Fast response time — typically less than 15 milliseconds to 90% of flow change for precise, real-time readings
• Dual heated sensing elements — allows integration into virtually any air/fuel system regardless of ducting assembly configuration
• Multiple sensing elements — eliminates sensitivity to supply voltage fluctuations and noise on power ground lines
• Wide temperature range — high-quality sensing elements deliver consistent performance across a broad range of ambient temperatures, with cold sealing rated to -50°C
• Calibrated to OE specifications — tested using OE-grade equipment to ensure accurate airflow output and reduce comebacks
• Probe-style design (where applicable) — eliminates the need to replace the full flow tube, reducing repair time and cost

A failing MAF sensor commonly causes symptoms such as rough idle, sluggish acceleration, poor fuel economy, or stalling. The Delphi AF10441 is a precision-engineered replacement that helps restore fuel economy, reduce emissions, and maintain drivability.
