Abstract
A deviation DGAIR between a first induction air volume GAIRTH that is calculated (S) based on a detected value (Gair) of an air flow meter and a second induction air volume GAIRPB that is calculated (S) based on an absolute pressure (PBA) is calculated (S), and a mean value DGAIRAVE of the deviation DGAIR is calculated (S, S), whereby when a difference DDGAIR between the deviation DGAIR and the mean value DGAIRAVE is larger than a predetermined value DGAIL1 (or when a correction mode AFMMODE is 1), secondary air is determined to be supplied to an engine, and the first induction air volume GAIRTH is then corrected (S, S).
