Abstract
Some embodiments of the teachings herein include methods for operating an exhaust gas sensor with a pump electrode, a measuring electrode, and a reference electrode. An example includes: discharging oxygen from the measuring cavity by applying a measurement current to the measuring electrode so a measurement voltage between the measuring electrode and the reference electrode is kept at a predetermined first setpoint value; discharging oxygen from the pump cavity by applying a pump current to the pump electrode so an electrode voltage between the pump electrode and the reference electrode is kept at a predetermined second setpoint value; determining a nitrogen oxide value based at least in part on a value of the measurement current; adapting the first setpoint value for the measurement voltage based on the determined nitrogen oxide value; and/or adapting the second setpoint value for the electrode voltage based on the determined nitrogen oxide value.
