Abstract
Methods for detecting the type of lambda probes having at least two electrodes disposed on and/or in a solid electrolyte, of which at least one electrode is separated from a gas mixture by a diffusion barrier, and a pump current Ip being applied to at least one of the electrodes. Either the internal resistance of the lambda probe between the electrodes is determined and the type of probe is inferred on the basis of this resistance, or currents are impressed between the electrodes and the type of probe is inferred based on the voltages or resistance ratios thereby resulting.
