Estimating the term…
An internal combustion engine control apparatus includes a secondary air supply device having a secondary air supply passage that supplies secondary air pumped by an air pump into an exhaust system of an internal combustion engine and an opening/closing unit that opens and closes the secondary air supply passage. A controller provided in the internal combustion engine control apparatus sets the opening/closing unit in an open condition such that the secondary air is supplied to the secondary air supply passage, and then executes foreign matter removal control in which the opening/closing unit is opened and closed. As a result, foreign matter caught in an ASV during AI control is removed immediately. By implementing OBD after removing the foreign matter, detection of an open sticking abnormality caused by foreign matter caught in the ASV is suppressed.
