A rotation sensor has a sensor and a processing circuit that are provided as an integrated circuit chip (IC chip). The sensor has a magnetic resistance element. The rotation sensor senses an angular change of a magnetic vector as a change of resistance. The rotation sensor is located to face a rotor, or a helical gear used in an automatic transmission. The magnetic resistance element is located such that a sensing plane thereof is parallel to a hypothetical plane perpendicular to the line of inclination of each tooth of the rotor.

The full bridge circuit in a pressure sensor including semiconductor piezoelectric resistive elements in a pressure detection structure is connected to a filter. That is, first and second output terminals of the full bridge circuit is connected to a capacitor. One end of the capacitor is connected to the first output terminal through a first resistor. The other end of the capacitor is connected to the second output terminal through a second resistor. In an exhaust system of an engine, the pressure of the exhaust gas is detected to detect clogging in the black smoke removing unit. The filter removes the pulsate component in the detection signal derived from the pulsate component in the exhaust gas.
