Abstract
A method for line assignment of a short-circuit of a broadband lambda sensor having an upper or a lower short-circuit potential, wherein the broadband lambda sensor has a sensor and multiple sensor lines. The method comprises establishing a conductive connection of at least one sensor line of the multiple sensor lines via a limiting resistor to a reference potential; comparing a sensor line potential of at least one sensor line to be checked of the multiple sensor lines to the reference potential or the short-circuit potentials; classifying () the at least one sensor line to be checked as not short-circuited with the upper or the lower short-circuit potential if it is established upon the comparison that the at least one sensor line potential is inside the reference potential range or if it is outside the short-circuit potential ranges; and assigning the short-circuit to at least one sensor line not classified as not short-circuited.
