Fault description
WARNING: This page does not describe the selected car, but rather 59 other vehicles, including the 2018 BMW X4, 2018 BMW 320i xDrive, 2018 BMW 320i, 2017 BMW X4, and 2017 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
Diagnosis monitors whether the throttle valve reaches the lower mechanical limit position during repeated adaptation.
Fault monitoring conditions:
The fault is recognized when the specified limit values for the permissible signal voltages are not achieved during initial adaptation. (Signal voltage sensor 1 less than 0.27 V, signal voltage sensor 2 greater than 4.73 V) or if the total of the signal voltages for sensors 1 and 2 deviates from 5 V by more than 0.6 V.
