Signal shape and setpoint values

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 engine control unit receives a measured value between 0 and 5 volts from the hall effect sensor. With the aid of the taught-in bottom limit position and an encodable slope, the DME converts this voltage into the throttle valve opening angle. The diagnosis monitors the two signals for an upper and lower voltage limit.
