The purpose of fuel-injection is to provide an optimal combination of fuel and air for combustion, and produce an ideal amount of power based on your driving conditions. The engine in your Hummer needs the mass air flow sensor to measure the density and temperature of the air flowing through the intake. The engine control module then adjusts the amount of fuel used by the injectors to maintain the best air/fuel ratio based on those readings from the MAF sensor. This ensures optimum power production and fuel economy for your Hummer.
