Abstract
A controlling device for an internal combustion engine includes an estimating portion to calculate an estimation value relative to an open degree of a valve based on a predetermined estimation formula. A signal of a sensor is changed, when the valve has a predetermined open degree defined between a full close and a full open. The estimating portion determines that an actual open degree of the valve is smaller than the predetermined open degree, in a case that the signal of the sensor is not changed when the estimation value becomes equal to or larger than the predetermined open degree.
