Abstract
A method for checking the functionality of a water adsorber in the exhaust of an internal combustion engine is provided. A sensor measures the temperature of the exhaust gases downstream in the flow direction from the water adsorber, and the functionality of the water adsorber is judged based on the change over time in the rate of increase in the sensed temperature after the internal combustion engine has been started.
