Abstract
An throttle-opening detecting apparatus for an internal combustion engine includes a fully-closed state value learning unit for storing and updating as a fully-closed state learned value a minimum value of an output of a throttle-opening sensor, and a judgment unit for judging the fully closed state of the throttle valve based on comparison of the throttle-opening sensor output and the fully-closed state learned value. The judgment unit includes a first element for judging the throttle valve as being in the fully closed state when the throttle-opening sensor output is less than a first judging value which is obtained by adding a first threshold value to the learned value, and a second element for judging, when the throttle-opening sensor output is greater than the first judging value and less than a second judging value which is obtained by adding a second threshold value to the learned value, the throttle valve as being in the fully closed state after lapse of a predetermined time.
