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.
Thanks to a residual oxygen content that equates to a mixture composition of lambda = 1, the voltage measurement on the measuring cell indicates a voltage of 450 millivolts. When lambda = 1, the composition of the exhaust gas of the different material is ideal.
