Abstract
An evaluation and control unit for operating a wideband lambda sensor that has at least two electrical lines, the evaluation and control unit having at least two electrical terminals for electrical connection to the electrical lines of the wideband lambda sensor. Each of the electrical terminals has assigned to it a respective electrical switch via which each terminal is capable of being individually connected to at least one defined electrical potential. Each switch is voltage-resistant against the maximum short-circuit voltage that is to be expected at the respective terminal in case of fault. In addition, a method is described for the line-specific short-circuit diagnosis of the wideband lambda sensor (pinpointing).
