Abstract
The throttle valve control device of this invention controls a throttle based on outputs of a position sensor including a first sensor and a second sensor which detect a position of a same object, wherein the output of the first sensor and the output of the second sensor change opposite to each other depending on a change in the position of the object, and the throttle valve control device determines the position sensor abnormal when a variation in the output of the first sensor is equal to or greater than a first threshold value and a variation in the output of the second sensor is equal to or greater than a second threshold value.
