<p>The invention relates to a method for checking a multi sensor system 36 having a plurality of temperature sensors 38a-m of a vehicle, configures to detect temperatures of, for example, and engine and or exhaust gas after treatment device. The method comprises: assigning a plurality of the temperature sensors 38a-m to a predeterminable group; determining at least one sensor output of each temperature sensor 38a-m of the group, the respective sensor output characterizing a temperature; calculating at least one mean value of the sensor outputs; and checking the multi sensor system 36 in dependence on the calculated mean value. The method may further comprise determining a difference between the mean value and a respective sensor output and comparing the difference with a predetermined threshold value. Each temperature sensor may also be subjected to a range check.</p> |
