Abstract

A control apparatus of an internal combustion engine includes an electronic control unit which determines whether a throttle valve opening sensor is normal or faulty in accordance with an output from the sensor. If the throttle valve opening sensor operates normally, a target air-fuel ratio is set in accordance with the output of the sensor. On the other hand, if the throttle valve opening sensor is in trouble, the control unit sets the target air-fuel ratio to a ratio equal to or close to the stoichiometric air-fuel ratio in accordance with the output of an intake air amount sensor, whereby a stable operation of the internal combustion engine is ensured.
