Abstract
A method and a device for operating an internal combustion engine make it possible to monitor a temperature sensor or a lambda sensor in an exhaust system of the internal combustion engine for functionality in the entire operating range of the internal combustion engine. To that end, the plausibility of the signal of the temperature sensor is checked with a signal of the lambda sensor for a predetermined relationship.
