Abstract: A method for precise acquisition of a signal of a sensor, by an evaluation and control unit which has a multiplexer at whose inputs there is at least one reference voltage whose voltage value is known, a ground potential of the reference voltage, a measurement signal of the exhaust gas sensor, and a ground potential of the measurement signal. A computer is connected downstream from the multiplexer via a transmission path and via an ADC that converts a voltage between its two inputs into a digital value. The method provides that a plurality of individual measurements are carried out in which switching states of the multiplexer are modified, and digital values are subsequently acquired at the output of the ADC. The computer calculates a measurement value, corrected with regard to offset and gain, from these digital values.

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 (105) 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.
