Abstract
A binary lambda sensor has a first electrode arranged on the exhaust gas side, a second electrode arranged contiguous to a reference air volume, and a power source arranged between the first and second electrode. A potential difference between the first and second electrodes forms a measurement signal of the sensor. In a measurement operation of the sensor, the power source is operated in a measurement operating state and provides the measurement signal. To adjust a specified oxygen concentration in the reference air volume, the power source is operated in a regeneration operating state. If a specified condition is fulfilled and the engine is operating in a coasting mode, the power source is operated in the measurement operating state, and a power source adjustment signal is determined for the regeneration operating state based on the measurement signal, for the adjustment of the specified oxygen concentration in the reference air volume.
