Crankshaft Sensor: Top-Out

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2010 BMW M6, 2010 BMW M5, 2009 BMW M6, 2009 BMW M5, and 2008 BMW M6. However, it is still accessible from the selected car via links, so may be relevant.

Top-out of the crankshaft signal is monitored during normal engine operation over certain revs. If several sudden top-outs occur within a time constrained a loose or spuriously faulty crankshaft signal is detected.
