The apparatus for correcting air-flow sensor output includes an air-flow sensor sensing an air-flow in an intake of an engine, and other sensors sensing operating conditions of the engine. An electronic control unit determines whether the engine is operating in one of a first and second state based on the sensed operating conditions, and reads a correction factor from a data map based on the sensed operating conditions when the engine is operating in the first state. Also, the electronic control unit calculates a new correction factor based on the sensed operating conditions and stores the new correction factor in the data map when the engine is operating in the second state. Then, the electronic control unit determines a corrected air-flow quantity based on the sensed air-flow and one of the read correction factor and the calculated correction factor.
