Abstract
In a method for controlling a switching flap () arranged in an intake pipe connected with an internal-combustion engine the switching flap () is rotated with the aid of a switching-flap shaft () connected with an electromotor (). With the aid of a position-detecting device () an end position of the switching flap () is detected. Subsequently, a rotation force is continued to be applied to the shaft () to hold the switching flap () in the end position. For detecting a breakage of the switching-flap shaft (), an error message is generated when the switching-flap shaft () continues to rotate beyond the end position.
