Characteristic curve 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 broadband oxygen sensor can be used to steplessly measure a Lambda value between 0.8 and 2.5 (constant characteristic curve). The Lambda oxygen sensor is most sensitive in the range around Lambda value = 1 am.
