In a method for checking the plausibility of sensor signals, a first sensor element detects at least one first physical quantity and outputs it as a first sensor signal, and a second sensor element detects a second physical quantity correlated with the first physical quantity and outputs it as a second sensor signal. The first sensor element has a first reliability range having an upper limit and/or a lower limit, which range is related to the second physical quantity. The first physical quantity detected by the first sensor element is recognized as plausible if the second physical quantity detected by the second sensor element lies within the corresponding first reliability range of the first sensor element.
