Abstract

The invention relates to an exhaust gas probe (120) for measuring properties of the exhaust gas of internal combustion engines, wherein at least one data storage unit (135) is arranged in a circuit associated with the probe, in particular arranged in a probe plug (130) or a connecting element associated therewith. The following properties and/or adaption functions characterizing the probe (120) are stored or storable in said data storage unit: —fluctuations of heating resistances that are due to the production process and/or—parameters that characterize the aging of the probe (120), and/or—the shut-off state, in particular data that characterize the execution of an interval measurement for regenerating the exhaust gas probe or of a delayed shut-off and/or—data for adapting the probe (120) to different control devices (140) of internal combustion engines and/or—the number of operating hours of the probe and/or—the operating parameters of the probe in a previous specifiable time period.
