Abstract

The invention is directed to a method of diagnosing a catalytic converter mounted in the exhaust-gas system of an internal combustion engine. An exhaust-gas probe is mounted rearward of the catalytic converter and at least one misfire of a combustion of the engine is stimulated. The reaction of the exhaust-gas probe to the stimulation of the misfire is evaluated to diagnose the catalytic converter. The invention is also directed to an arrangement for diagnosing a catalytic converter.
