Abstract
Device and method for correcting an offset in a signal of a first sensor for determining a residual oxygen content in an exhaust gas. A first actual ratio of air and fuel being determined as a function of a first residual oxygen content, a second actual ratio of air and fuel being determined as a function of a second residual oxygen content, a first offset of a first actual ratio relative to a reference ratio being determined for the first actual ratio when the second actual ratio is greater than the reference ratio, a second offset of a first actual ratio relative to the reference ratio being determined for the first actual ratio when the second actual ratio is smaller than the reference ratio, and a deviation being detected between the first offset and the second offset.
