Abstract
A method for operating a particle sensor (). The particle sensor () has at least two inter-digital electrodes () which engage one in the other and to which a sensor voltage U() is applied in order to determine loading of the particle sensor () with soot particles (). A sensor current I() across the electrodes () is measured and evaluated. In order to remove the loading with soot, a heating element () heats the particle sensor () in a regeneration phase. The method characterized in that the sensor current I() is determined, and a shunt diagnosis of the particle sensor () is carried out in accordance with the measured sensor current I().
