The initial determination value generation unit performs an operation using the detection signals to generate an initial determination value corresponding to the angle sensor condition. The correction processing unit performs correction processing on the initial determination value to generate a corrected determination value. The determination unit determines whether the angle sensor is in a normal condition on the corrected determination value basis. The initial determination value contains a variation component which varies depending on an angle to be detected.
