MASS AIR FLOW SENSOR (MAF) - Autoditex

A mass air flow (MAF) sensor responds to the amount of air flowing through a chamber containing the sensor. It is intended to be insensitive to the density of the air. The sensor for volume consumption of air is used in many systems for management of engines for measuring value of the transitory cost of air.
