It detects measurement values for the camshaft that actuates gas exchange valves to check the function of one or more switching elements and displays a function signal if there is a defined deviation from one or more fixed values. The measurement parameter can be camshaft rotary oscillation signals. Independent claims are also included for the following: a method of checking the function of one or more switching elements of a valve controller.
