  "textContent": "The method involves determining the time gradient of the sensor signal which characterizes the oxygen concentration. The time gradient is determined during a transition of a combustion engine (110) from an operational phase into a selected operational phase. The operational availability of a lambda sensor (130), for functions in the selected operational phase of the combustion engine, does not exist when the time gradient goes against zero. Independent claims are also included for the following: (1) a method for detecting the gas permeability of a lambda sensor surrounding protective tube; (2) a computer program; and (3) a computer program product.",
