Abstract
For operating a internal combustion engine a first characteristic value is determined depending on a distance integral of at least a portion of a control signal of an oxygen sensor control based on control reference signal characteristics across a given time period. Depending on the first characteristic value (KW) a quality value (GW) is determined. Depending on the quality value (GW) either the existence or the non existence of an error of the exhaust sensor is detected.
