Abstract:
A method for on-vehicle functional diagnosis of a soot sensor and/or for detecting further components in the soot in a motor vehicle having an internal combustion engine, the soot sensor connected electrically to an evaluation circuit. To specify a method for functional diagnosis of a soot sensor and/or for detecting further components in the soot, by which it is possible to detect a faulty soot sensor and/or further components in the soot in an economical manner, the evaluation circuit measures a temperature coefficient of the soot sensor and detects the faultiness of the soot sensor and/or the presence of further components in the soot from the temperature coefficient of the soot sensor.
