摘要：
A method for the on-board functional diagnosis of a soot sensor and detection of further constituents in the soot in a motor vehicle having an internal combustion engine. The soot sensor is connected electrically to an evaluation circuit in the motor vehicle. A faulty soot sensor and/or further constituents in the soot can be detected in an inexpensive way. The evaluation circuit measures the voltage coefficient of the soot sensor and detects the defectiveness of the soot sensor and/or the presence of further constituents in the soot using the voltage coefficient of the soot sensor.
