Abstract
An exhaust gas sensor includes an element cover, a heater, a heater control section, and a cover state diagnosing section. The element cover accommodates a sensor element including a detection section and includes one or more gas flow holes. The heater heats the sensor element. The heater control section controls how the heater heats the sensor element. The cover state diagnosing section diagnoses a state of the element cover using heater information obtained when the heater is operated by the heater control section. The cover state diagnosing section includes a diagnosability determining section, which determines whether the state of the element cover is diagnosable based on an accuracy of the heater information obtained from an operating state of the heater and a surrounding environmental state of the element cover.
