Abstract
During lean operation of the internal combustion engine, preferably in relatively long-lasting overrunning shutoff phases, the output voltage of the sensor signal is regulated to a predetermined desired value via the heating control unit. If within the diagnosis period, fewer than a predeterminable number of monitoring results are within a tolerance range located around the desired value, then the heating circuit is classified as defective.
