A mass (air) flow sensor is used to find out the mass flow rate of air entering a fuel injected internal combustion engine. An air flow meter is necessary for the engine control to balance and deliver the correct fuel mass to the engine.
Air flow meter is an integral component of the computer controlled engine system found in most cars today. The information by the air flow meter is used to adjust spark timing, fuel delivery and spark advance. A fault in the Air flow meter sensor can cause a rough and poor fuel economy.
