Method and arrangement for checking a sensor signal

A method for checking a first sensor signal (S1) of a first sensor cluster (1) having at least a first sensor (2, 3, 4), in which - by the first sensor cluster (1) one or more physical parameters are detected in a first measuring area, which are supplied to a vehicle dynamics control system as controlled variables, - by evaluating a second sensor signal (S4) of a second sensor cluster (6) with at least one second sensor (7, 8, 9), it is determined whether a predetermined operating condition is present, wherein by the second sensor cluster (6) one or more of the physical variables are recorded in a different one of the first measurement area second measurement range, which are supplied to a passenger protection system as a manipulated variable, and - in the presence of one of the predetermined operating states for a presence or non-presence of a possible external disturbing influence on the first sensor signal (S1) is detected.
