Abstract

A method for regenerating a particle sensor, which comprises a ceramic base body, in the exhaust gas duct of an internal combustion engine for driving a motor vehicle, wherein a particle loading of the particle sensor is determined by applying an electrical voltage between at least two electrodes with interdigital arrangement, a temperature of the particle sensor is determined with a temperature sensor mounted to the ceramic base body or from the electrical resistance of a heating element and said particle sensor is regenerated by means of heating with the electrical heating element.
