Abstract
In the change from lean to rich exhaust gas or vice versa, signals are recorded by a lambda probe and are used to diagnose the functional reliability of this lambda probe. So that special reliability of this procedure is ensured, the change is triggered by an event. The event can be defined by signals of the lambda probe or can be caused by control actions of the operator in the motor vehicle.
