Abstract
A method for operating an internal combustion engine, permitting a differentiation between an air error and a fuel error as part of mixture adaptation. In at least one operating state of the internal combustion engine a deviation in an air-fuel mixture ratio from a setpoint value is corrected. For this correction in the at least one operating state the particular deviation in the air-fuel mixture ratio is determined for at least two setpoint values. From these deviations an air error and/or a fuel error is determined.
