A method and apparatus for determining the mass air flow into an internal combustion engine without the use of a mass air flow sensor. Speed density and throttle position methods of estimating mass air flow are combined using a first Kalman filter. In one aspect of the invention, the input throttle position into the throttle position mass air flow estimate is the measured throttle position obtained from the throttle position sensor. In another aspect of the invention, the input throttle position into the throttle position mass air flow estimate is the output of a second Kalman filter, which uses as its inputs the measured throttle position obtained from the throttle position sensor and the desired throttle position obtained from the pedal position sensor.
