摘要

The method involves detecting the values for the diagnosis of active oxygen adjustment, where the former value represents the oxygen storage capacity of a catalyst (12), and the latter value represents the oxygen discharge capacity of the catalyst. A characteristic offset of an oxygen sensor (18) is calculated from the ratio of oxygen storage capacity to oxygen discharge capacity. An adaption of the characteristic offset takes place with a natural frequency control of the catalyst. Independent claims are included for the following: (1) a computer program for executing a method for operating an oxygen sensor arrangement; and (2) a computer program product for executing a method for operating an oxygen sensor arrangement.
