The invention relates to a method of controlling the function of a sensor (10) for detecting particles, in particular soot, wherein the sensor (10) comprises at least two measuring electrodes (20, 22) 20, and 22 are disposed. The method includes performing a first current / voltage measurement to determine a first measurement variable, performing a second current / voltage measurement to determine a second measurement variable, wherein the measurement electrodes (20, 22) is connected to another potential (50), performing a third current / voltage measurement to determine a third measurement variable, and comparing the first measurement variable and the second measurement variable And forming a correction value for correcting the second measurement variable by three measurement variables. |
