Method for operating exhaust gas sensor for determining composition of exhaust gas of internal combustion engine, involves activating different functions of exhaust gas sensor depending on operating state of exhaust gas sensor

摘要

The method involves activating different functions of the exhaust gas sensor depending on an operating state of the exhaust gas sensor, if the operating state allows the corresponding function. The temperature (11) of the exhaust gas sensor or a characteristic variable dependent on the temperature of the exhaust gas sensor is applied as the operating state. The threshold value (20,21,22,23,24) of the operating state of the exhaust gas sensor is preset, from which the corresponding functions are activated. An independent claim is included for a device for operating an exhaust gas sensor for determining the composition of an exhaust gas.
