Abstract: An output terminal of a signal output device is connected through a branch path to a voltage dividing point in a main path, and transmits an output signal based on a voltage of the voltage dividing point to an outside. A signal generation circuit adjusts the voltage of the voltage dividing point and generates the output signal. A short circuit detection circuit detects a short circuit between the output terminal and another terminal when a current flowing in the branch path is greater than a predetermined short circuit detection threshold. A switching circuit switches a current carrying capacity or a configuration of the signal generation circuit to limit a short circuit current flowing in the branch path when the short circuit is detected. The short circuit current is set to a value equal to or greater than the short circuit detection threshold and less than a current upper limit value.

Abstract: An ECU loads detected values of a rotation angle sensor and a pressure sensor which are mounted to an electric throttle, and executes an abnormal-sensor determination control to determine whether one of the rotation angle sensor and the pressure sensor is abnormal. Specifically, the ECU determines that one of the rotation angle sensor and the pressure sensor is abnormal, in a case where a state that a tendency of the actual opening angle detected by the rotation angle sensor does not match a tendency of the pressure detected by the downstream pressure sensor has continued for a period greater than or equal to a predetermined period. Therefore, since the pressure sensor can replace the rotation angle sensor used for detecting abnormality in a conventional technology, two rotation angle sensors can be reduced to one rotation angle sensor, and a cost is reduced.

Abstract: A position detector apparatus includes a detector part, wiring, a resin part, a resin body, a terminal, and a lead frame. The resin part has a thickness at a wiring side portion of the detector part that is greater than a thickness on a side opposite to the wiring side portion.

Further, the resin body has a thick-resin portion and a thin-resin portion. The thickness of the thin-resin portion allows a predetermined amount of dislocation of the detector part. Therefore, if the detector part is exposed, water is prevented from intruding the lead frame and the terminal.
