Structure and inner electrical connection
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. 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.
