Abstract

A method for checking the function of a sensor for detecting soot is provided, the sensor including at least two measuring electrodes situated on a substrate made of an electrically insulating material, and a heating element, the method including: carrying out a first current-voltage measurement at a first temperature to ascertain a first measured variable, carrying out a second current-voltage measurement at a second temperature to ascertain a second measured variable, and forming a difference between the first measured variable and the second measured variable.
