摘要： A method for operating a soot sensor that has an interdigital electrode structure, to which a measurement voltage is applied. Soot particles from an exhaust gas flow are deposited onto the interdigital electrode structure and the measurement current is evaluated as a measure of the soot load of the soot sensor. The interdigital electrode structure is burned clean at or above a predetermined soot load, which is detected by means of an upper current threshold. The method includes burning the interdigital electrode structure clean by heating up the soot sensor after the upper current threshold has been reached; monitoring the measurement current while the interdigital electrode structure is being burned clean; and stopping the burning clean when the value of the measurement current has reached a lower current threshold.

摘要： The internal combustion engine includes at least one cylinder, an exhaust gas tract having a measuring device, and a tank ventilation system having a purge air line, which provides pneumatic communication between the tank ventilation system and the cylinder. The purge air line has a sensor for ascertaining a hydrocarbon content of a gas flow from the tank ventilation system to the at least one cylinder. Fuel metering into the cylinder is controlled dependent on the ascertained hydrocarbon content. An exhaust gas characteristic of an exhaust gas flow that flows in the exhaust gas tract is detected by the measuring device and compared with a specified target value. If the ascertained difference between the detected exhaust gas characteristic and the specified target value exceeds a specified threshold, a test is carried out to determine whether the sensor has a malfunction.
