DENSO DMA-0103 Mass Air Flow Sensor MAF

The DENSO DMA-0103 Mass Air Flow Sensor is an OE-quality replacement sensor that accurately measures the volume of air entering the engine and sends this critical data to the Engine Control Unit (ECU). This precise measurement enables the ECU to calculate and deliver the optimal fuel-to-air ratio for maximum engine efficiency, performance, and emissions control.

Key Features:

• 5-pin electrical connector for reliable signal transmission
• Plug-in type design without housing for easy, direct installation
• Electric operating mode with platinum wire sensing element
• Advanced air bypass structure reduces contamination exposure
• Glass film coating protects sensing element from contaminants
• Compact, lightweight design reduces installation time
• First Time Fit engineering ensures proper mounting with minimal installation issues

DENSO pioneered the world's first plug-in mass air flow sensor in 1966 and continues to lead with innovative sensor technology. This sensor features a unique bypass passage design that minimizes air turbulence and protects the platinum wire sensing element from dirt and debris, maintaining detection accuracy throughout its service life. The DMA-0103 is manufactured to meet or exceed OE specifications and is designed for select Land Rover and Volvo applications.
