Abstract
A control unit and a method for diagnosing lines between a wideband lambda sensor and the control. By means of specific circuitry and evaluation, it is determined, for each individual line, whether or not there is an interruption or failure of the line in question. A method for more accurately measuring the value of a calibration resistor of the wideband lambda sensor is also described.
