A device and a method for detecting an erroneous determination of a geographical position of a vehicle. The device includes a sensor that is configured to determine a first yaw rate of the vehicle, a satellite navigation receiver that is configured to receive satellite signals during a predetermined time period, to determine a multiplicity of geographical positions of the vehicle on the basis of the received satellite signals, and to determine a geographical reference position of the vehicle on the basis of the multiplicity of geographical positions, and a processor that is configured to determine a second yaw rate of the vehicle on the basis of the determined geographical reference position of the vehicle, and to compare the first yaw rate with the second yaw rate in order to detect the erroneous determination of the geographical position of the vehicle.

The operating temperature of a gas sensor capable of sensing a gas or a gas composition at a high temperature, for example 1000&#xb0; C. is maintained constant over the entire volume of a gas sensor layer or function layer () secured to a sensor carrier section of the gas sensor by supplying heat to the gas sensor layer () in such a way that varying heat dissipations in the sensor carrier section are compensated. For this purpose, an electrical heater for heating the gas sensor layer () has individual heater sections with different heating resistance values which depend on a spacing between any individual heater section and the tip of the sensor carrier section.
