ABSTRACT:
Techniques are provided for controlling the operation of an air-fuel ratio control apparatus for an internal combustion engine including feedback control of the air-fuel ratio control. The pump-driving voltage for flowing the pump-driving current used for changing the oxygen concentration is monitored and feedback control is suspended when the pump-driving voltage departs from a predetermined range.
