Crankshaft sensor (Ver. 2): Notes
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 crankshaft sensor is attached to the gearbox case.
The crankshaft sensor records the position of the crankshaft with the aid of a sensor wheel screwed to the flywheel. The engine control uses this to calculate the engine speed. The crankshaft sensor and camshaft sensor are necessary for the fully sequential fuel injection (fuel injection takes place individually for each cylinder at the specific ignition point).
The signal from the crankshaft sensor means that the engine control also evaluates the crankshaft acceleration. The crankshaft acceleration provides an indication of the combustion quality of individual cylinders.
