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 accelerator-pedal module functions with induction. The two sensors receive separate 5-volt power supplies from the engine-management control unit, to which they also have separate earth connections. The electronic processing circuitry generates analogue voltage signals, reflecting the accelerator pedal's position, for use by the engine-management control unit. The sensor signals are transmitted to the engine-management control unit separately.
