Abstract (en)
[origin: WO2021032360A1] A method for operating an exhaust-gas sensor in an exhaust-gas section of an internal combustion engine of a vehicle, wherein the exhaust-gas sensor (10) has a ceramic sensor element (12) with at least one measuring electrode (16, 18) and with a heating device (30), wherein, on the basis of data relating to the internal combustion engine and the exhaust-gas sensor, a binary dewpoint end signal (TPE) is calculated which indicates whether or not the occurrence of liquid water in the exhaust-gas section is still to be expected, characterized in that, whenever the vehicle is shut down and at the same time the dewpoint end signal (TPE) has the value that signals that the occurrence of liquid water in the exhaust-gas section is still to be expected, the sensor element (12) is heated for a certain time to a temperature (T) by means of the heating device (30) thereof such that the sensor element (12) dries.
