摘要： A procedure for a reasonability check of the signal of a temperature sensor that is arranged in a reducing tank, in particular a HWL-tank, is thereby characterized, in that the tank level is detected by a tank level sensor that is arranged almost at the same filling level position as the temperature sensor, in that the tank level sensor signal is compared to the temperature sensor signal and then, if default tank level sensor signals correlate within default limits with default temperature sensor signal values, a functioning temperature sensor and/or a functioning tank level sensor are indicated.

摘要： A procedure for checking the functionality of an electric heating device (10) with at least one PTC-element (13, 14) is suggested. The electric heating device (10) is operated at a battery voltage. When controlling the heating device (10) it is impinged with a current and at least one measuring value is detected, which represents the current that flows through the heating device. The measuring value for the current is compared to at least one reference value with a default tolerance width while considering the battery voltage. In the case of a measuring value that deviates from the reference value an error can be assumed.

摘要： A method and device for treating exhaust gases of an internal combustion engine with a reducing agent introduced into the exhaust gases. The reducing agent is pumped out of a reactant reservoir and to a dosing valve so that after the dosing valve is opened, the reducing agent can be introduced into the engine's exhaust gas line in a dosed manner. Reducing agent can be conveyed back from the delivery device to the reservoir via a return line. The reducing agent can circulate between the delivery device and the reactant reservoir thereby, particularly when the dosing valve is closed, preventing the reactant from freezing.
