摘要: A degradation detector of an exhaust gas sensor is disclosed. The comprises a first heater resistance estimator ( 16 ) for estimating that heats the sensor, based on device sensor; calculator 17 calculating heater, current heater; and determiner 18 determining whether degraded, by comparing estimated calculated heater.
