1. The method of determining a Lambda value with a wideband Lambda sensor of an internal combustion engine of a motor vehicle, the method including measuring a first oxygen concentration in a lean operation and a second oxygen deficit in rich operation from a measured pumping electricity and sensitivities of the wideband Lambda sensor to gasses detected and gas concentration rations;

  • and determining the Lambda value from the first and second oxygen concentrations.
