Abstract
A method and device for checking temperature values of a temperature sensor of a combustion engine are provided. A first temperature actual value is recorded during a first length of time at an ending of the operation of the combustion engine. A second temperature actual value is recorded during a second length of time during an operating state reflecting the starting of the combustion engine. A turn-off length of time of the combustion engine is determined between the ending of the operation of and the subsequent starting of the operation of the combustion engine. In addition, a temperature set value is established based on the first temperature actual value and on the turn-off length of time. An error of the second temperature actual value is recognized based on the second temperature actual value and on the temperature set value.
