First of All – What is a Mass Air Flow Sensor?

As described via Wikipedia: “A mass flow sensor is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure.”

Why is a Mass Air Flow Sensor Important?

As it pertains to your Mercedes, your mass air flow sensor measures the temperature of air, as well as the quantity of air coming in. This is communicated to your vehicles computer to help your fuel injection system function optimally.

As mentioned above, your mass air flow sensor mixes an appropriate ratio of fuel to air in order for ignition and combustion levels to perform, which a Mercedes owner would expect regardless of climate or driving conditions
