ABSTRACT:
An air flow sensor failure determination apparatus for determining a failure of an air flow sensor for an internal combustion engine in which an air flow sensor, a throttle and a pressure sensor disposed downstream of the throttle are provided in an air induction passage, the air flow sensor failure determination apparatus comprising a first calculating unit for calculating a first induction air volume based on an output signal from the air flow sensor, a second calculating unit for calculating a second induction air volume based on an output from the pressure sensor, and a determination unit for determining a failure of the air flow sensor based on a comparison between the first induction air volume and the second induction air volume.
