摘要： A method for identifying cable faults at the terminals of a broadband lambda probe comprising a Nernst cell and a pump cell in the exhaust gas duct of an internal combustion engine. The broadband lambda probe has a reference electrode terminal RE, an internal pump electrode terminal IPE and an external pump electrode terminal APE. A pump current is applied to the broadband lambda probe and a pulsed reference pump current is applied to the broadband lambda probe. Cable faults are identified by the evaluation of potential swings in current.

摘要： A measured value of a sensor element is obtained during repeatedly executed measuring periods for performing different measurements and for setting different operating states, the sensor element being electrically connected in a periodically alternating manner, in consecutive switching positions, in a predefined order, where at least one measurement for determining the measured value is performed repeatedly within a measuring period for determining individual values at predefined switching positions, the measured value being determined from the individual values. Using the switching position within the measuring period, the operating state of the sensor element preceding the individual measurement, and therefore, the influence of the preceding circuit configuration on the individual measured value, is known, and the individual values are correspondingly corrected. By correcting the individual values, the measured value determined from the individual values is also corrected.

摘要： A method for determining a polarization of a pump cell and/or a Nernst cell of a lambda probe for the diagnosis of the broadband lambda probe. A voltage or current pulse is applied to the pump/Nernst cell in a first method task, and, in a second method task, a voltage at the pump cell and/or the Nernst cell, or a variable that is related to the polarization or its time characteristic is determined and used as a measure of the polarization, and the function of the broadband lambda probe is monitored via the ascertained polarization. The determination of the polarization may be performed as a voltage measurement performed once or multiple times, or by determining the effect of the polarization in an associated controller, such as a pump current controller of an engine control unit. The variable associated with the polarization may be the reaction of the pump current control.
