Abstract

A method and an arrangement for monitoring an exhaust system (10) of an internal combustion engine are disclosed. In said method and arrangement temperature variations are measured upstream and downstream of an installation location (16) of a catalytic converter (18) in order to determine whether or not said catalytic converter (18) is installed.
