Abstract

A method and device for the diagnosing and monitoring vehicle components, wherein measurements with respect to a first measuring point, a second measuring point, a third measuring point and a fourth measuring point are performed and a first measured value set, a second measured value set, a third measured value set and a fourth measured value set are formed, where a reference value set is determined with respect to a reference point via the first measured value set, the second measured value set and the third measured value set, where a test value set is formed with respect to the fourth measuring point via the reference value set, and where a fault in or damage to the fourth sensor is detected by comparing the test value set with the fourth measured value set such that a high level of availability when used by a vehicle is achieved.
