Abstract: A deterioration estimator for an electronic throttle device allows a throttle valve to be driven by a drive mechanism. The throttle valve is continuously operated to open and/or close. If operated to open, it opens from a first opening position, which is on a closed side from an opener opening position and in which the throttle valve is biased to an open side by an opener mechanism, to a second opening position, the second opening position being on an open side from the opener opening position with the throttle valve being biased to the closed side by the opener mechanism. If operated to close, the throttle valve is operated to close from the second opening position to the first opening position. A deteriorated condition of the electronic throttle device is estimated by detecting a behavior of the drive mechanism when the throttle valve passes by the opener opening position.
