Air Flow Sensor | Mazda CX-7 (2010-2012)

Your Mazda CX-7's Air Flow Sensor determines the mass flow rate of air that enters the fuel-injected internal combustion engine. The air mass information is necessary for your Mazda CX-7's Engine Control Unit (ECU) to correctly balance and deliver the correct amount of fuel to the engine. When there is a problem with the Air Flow Sensor, symptoms often include: Engine having problems starting, Engine Stalling, Hesitation and Jerking during Acceleration, Excessively Rich or lean Idling.
