Abstract
A device and a method for monitoring a sensor for an exhaust-gas after-treatment system, in particular a temperature sensor. In specified operating states, a first signal from the first sensor to be monitored may be compared to a second signal from a second sensor. Errors may be detected when at least the two signals differ from one another by more than a value.
