1. An internal combustion engine controller that controls at least a throttle opening degree, said controller comprising: a target opening degree calculating section that selects either a primary request value for a throttle opening degree that corresponds to a torque request for an internal combustion engine or a secondary request value for a throttle opening degree that corresponds to another request and that calculates a target throttle opening degree from the selected one of the primary and secondary request values; and an abnormality occurrence determining section that, if the target opening degree calculating section has selected the primary request value, determines whether or not there has occurred an abnormality, in accordance with a magnitude of a deviation of the primary request value from the target throttle opening degree and that, if the target opening degree calculating section has selected the secondary request value, determines whether or not there has occurred an abnormality, in accordance with whether or not the target throttle opening degree is greater than or equal to a predetermined upper limit value.
