Beschreibung
Zusammenfassung:	A sensor control apparatus including a gas sensor having a sensor element, a housing and a base part formed of a resin. The apparatus includes a heating part and a control part. When the control part determines that a predetermined automatic stop condition has been satisfied, the control part switches from a control for maintaining the temperature of the sensor element at an activating temperature to a control in a stop state for reducing at least one of voltage and current supplied to the heating part so as to set a temperature of the base part to a value equal to or lower than a shape holding temperature of the resin. Also disclosed is a sensor control method for holding a temperature of a sensor element to an activating temperature.
