Abstract
A final control element for a control unit, for a throttle body located in a conduit carrying a gaseous medium in an internal combustion engine, is disclosed which has a control shaft, supporting the control unit in a manner fixed against relative rotation; a power takeoff member of a final control element gear, the power takeoff member being seated on the control shaft in a manner fixed against relative rotation; and an error sensor, detecting the rotary position of the control shaft, with a rotor part that is connected to the control shaft in a manner fixed against relative rotation. The error sensor is a contactless measurement rotary angle sensor, whose rotor part is integrated by material and positive engagement with the drive member. Preferably, the rotor part is made of sheet metal, and the positive engagement is established by spraying the power takeoff member, made of plastic, onto it. The rotor part is welded to the control shaft.
