Abstract
In the calibration of a lambda sensor (), inaccuracies occur during a fuel cut-off overrun phase depending on the temperature. A method is proposed for correcting an output signal of a lambda sensor () of an internal combustion engine (), having the following steps: detection of a fuel cut-off overrun phase of the internal combustion engine (), sensing of an exhaust-gas composition by the lambda sensor () during the fuel cut-off overrun phase, sensing of a temperature which represents a measure of the intake air of the internal combustion engine (), calibration of the lambda sensor () based on the second temperature.
