Abstract: In a change from a lean to a rich exhaust gas mixture, a characteristic behavior appeal's in a short time interval in the vicinity of the lambda jump of an upstream catalytic converter lambda probe in the signal characteristic which is measured by a downstream catalytic converter lambda probe. From the signals in small intervals, around the instant of changing, the reliability performance of the downstream lambda probe can be deduced without the actual probe jump in curves of the voltage characteristics having to be considered.
