Abstract
In a method for diagnosing a particle filter of a motor vehicle a particle sensor which is connected downstream and has a ceramic sensor element is used, wherein, for the particle sensor, regeneration () of the ceramic sensor element is provided by thermal heating to a specific temperature and for a specific time after the start of the motor vehicle. Within the scope of an on-board diagnosis a confirmed diagnosis result is output after a repeated occurrence of a first diagnosis result. In the proposed method reduced regeneration () of the ceramic sensor element takes place after a first diagnosis result ().
