Abstract
In a method for checking temperature values of a temperature sensor of an internal combustion engine, a first temperature value is recorded during a first predefined time period close in time to an operating state of the starting of the internal combustion engine. With the method a check is made to determine whether a cold start of the internal combustion engine is present. An error in the first temperature value is detected if the cold start is detected and the first temperature value is greater than a temperature threshold value.
