Structure and inner electrical connection
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
The servo-motor employed to adjust the position of the throttle valve is a DC motor. The throttle-valve sensor is a Hall-effect device. The hall effect sensor determines the revolutions of the servomotor. This provides the basis for calculating the position of the throttle valve.
