Abstract
A method for monitoring a component situated in an exhaust gas region of an internal combustion engine in which the low pass behavior, which is determined by the heat capacity of the component, is monitored by a valuation of a measure of a first exhaust gas temperature, which appears upstream of the component that is to be monitored, and of a second exhaust gas temperature, which is recorded by a second temperature sensor downstream from the component to be monitored.
