置。[Scope of Claim for Utility Model Registration] A throttle valve operating motor that opens and closes the throttle valve, a motor driver that supplies a drive current to the motor according to a control signal, and a control signal that causes the throttle valve to open and close to a target opening. a motor control means for supplying the motor driver; an ignition operation detection means for detecting an ignition switch ON operation; and an ignition operation detection means for detecting an ignition switch ON operation; A check signal generating means for supplying a check signal output to the motor to the motor driver; a valve opening/closing operation prohibiting means for restricting the check signal and prohibiting the opening/closing operation of the throttle valve by the motor; a main circuit current detection means for detecting; a current check means for determining whether a detected value of the current flowing in the main circuit of the motor driver is within a normal range based on a check signal; A throttle valve characterized in that it has: control permission means for permitting operation of the motor control means; and abnormality notification means for notifying an abnormality of the motor driver to the outside when the value does not fall within a normal range. Control device.
