A method and device for the control of an exhaust treatment system, in particular on an internal combustion engine are disclosed. A special operation is periodically carried out, whereby the control and/or monitoring of the special operation is carried out depending upon a first parameter (01), characterising the oxygen concentration in the exhaust gases before the exhaust treatment system and a second parameter (02), characterising the oxygen concentration in the exhaust gases after the exhaust treatment system.
