ABSTRACT:
A temperature sensor control apparatus includes a reference potential section, a driving potential section set to a driving electric potential, a temperature sensor configured to vary a resistance in accordance with a temperature, and disposed between the reference potential section and the driving potential section, a conduction path, two reference resistance elements each connected in series with the temperature sensor, a potential controlled point disposed in the conduction path between the reference resistance elements, a potential setting section configured to set an electric potential of the potential controlled point to the driving electric potential; and a resistance switching control section configured to control the potential setting section to switch the electric potential of the potential controlled point, and to switch each of the reference resistance elements to one of an energized state and a deenergized state.
