Abstract

A method is provided for controlling the function of a sensor for detecting particles, in particular soot particles, the sensor including at least two measuring electrodes and a substrate on which the measuring electrodes are situated. The method includes the following: carrying out a first current-voltage measurement for ascertaining a first measured variable; carrying out a second current-voltage measurement for ascertaining a second measured variable, one measuring electrode of the measuring electrodes being applied to another electrical potential; carrying out a third current-voltage measurement for ascertaining a third measured variable; an configured forming a correction value for correcting the second measured variable with the aid of the first measured variable and the third measured variable.
