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 8):
The method according to  claim 1 , wherein the nitrogen oxide sensor is evaluated as being faulty if the ascertained value for both directions does not lie in the range of permitted values, or if said value does not lie in the range of permitted values only at the transition from the normal operating mode into the diagnostic mode or only at the transition from the diagnostic mode into the normal operating mode.
