Various embodiments relating to air-fuel ratio control are described herein. In one embodiment a method includes adjusting fuel injection to an engine responsive to air-fuel ratio sensor feedback with a first control structure, and in response to an air-fuel ratio sensor asymmetric degradation, adjusting fuel injection to the engine responsive to air-fuel ratio sensor feedback with a second, different, control structure.
