PROBLEM TO BE SOLVED: To provide a throttle valve control device further improving its safety and reliability and reducing manufacturing costs by revising a value even if a full-close position is erroneously learned since the full-close position is learned on the basis of results of monitoring of output signals of accelerator sensors of multiple system. SOLUTION: This throttle valve control device of an engine has: the accelerator sensors of multiple system detecting an opening of an accelerator pedal; and a throttle valve driven to be opened and closed through a motor on the basis of the output signals of the accelerator sensors. The device further comprises: a means for learning a full-close voltage of the accelerator sensors; and a means for determining each idle switch to the accelerator sensors of the multiple system. The means for learning the full-close voltage of the accelerator sensors upwardly revises a learned value of the full-close point voltage of the accelerator sensor on the side on which the idle-switch-off is determined, and learns the value, when a mismatching is found in on/off determinations of the idle switches by the means for determining the idle switch.
