After each fueling the Ethanel portion is determined by means of the O2sensor voltage upstream TWC in the fuel tank. If for example Ethanol was
refueled, the mixture is at first too lean (oxygen sensor voltage jumps back to 0 Volt). The lambda control reacts if the mixture to be enriched until
after fueling lambda = 1 is achieved again.
