Precision in Air-Fuel Management Modern internal combustion engines rely on accurate air-fuel mixture control for efficiency and emission reduction. Central to this process is the Air Mass Flow Meter (MAF sensor), which measures incoming air and transmits data to the Engine Management System (EMS). This allows the Electronic Control Unit (ECU) to fine-tune fuel delivery for optimal combustion.

Understanding Air Mass and Temperature Air density varies with temperature, affecting oxygen content. Warmer air is less dense, while cooler air contains more oxygen. Since combustion relies on oxygen, measuring air mass rather than volume ensures precise fuel injection.

Diagnosing MAF Sensor Issues:
A faulty MAF sensor can cause poor acceleration, rough idling, and increased fuel consumption
