Abstract
A sensor device includes two sensor parts and an ECU. An output division of one of the two sensor parts stops output of an output signal when a detected internal abnormality is a first abnormality. Further, when the detected internal abnormality is a second abnormality that is different from the first abnormality, the output division controls an abnormality signal to take a value indicative of the second abnormality. An abnormality determiner determines either of a signal obtainment abnormality or the first abnormality of the sensor part when the output signal is not obtained from the one of the sensor parts, or determines the second abnormality of the one of the sensor parts when the obtained output signal includes the abnormality signal having a value indicative of the second abnormality. Such determination, thus, enables the abnormality determiner to classify an abnormality caused in the sensor parts.
