Abstract:
A method is presented for checking the functional capability of a nitrogen oxide sensor ( 10 ) which has a first chamber ( 12 ) and a second chamber ( 14 ), wherein the first chamber has a first oxygen pump cell ( 20 ) and the second chamber has a second pump cell ( 34 ), in a normal operating mode of the nitrogen oxide sensor ( 10 ), an oxygen concentration level in the first chamber is reduced to a predetermined first value with the first pump cell, and an oxygen concentration level in the second chamber is reduced to a second value with the second pump cell, said second value being lower than the first value.

Claim (Index 9):
The method according to  claim 1 , wherein the value range which is valid for a functionally capable nitrogen oxide sensor ( 10 ) is ascertained by virtue of the fact that the oxygen concentration level in the first chamber ( 12 ) is set to a value which is increased in comparison with a normal operating mode of the nitrogen oxide sensor at the end of the production of the nitrogen oxide sensor or in the new state of the sensor when it is used in an exhaust gas system of an internal combustion engine, in that a change, occurring in reaction thereto, in a pump flow flowing in the second pump cell ( 34 ) is detected, and the change or a variable derived from the change is stored as a basic value for a value range which characterizes a functionally capable nitrogen oxide sensor ( 10 ).
