Crankshaft position sensor
The crankshaft position sensor (B600) is located on the left on the
timing case.
Task
The crankshaft position sensor (B600) makes electrical voltage
signals available to the engine management (MCM) control unit
(A4) for a rotating engine from which the rotational speed as well
as the position of the crankshaft can be determined.
Design
The crankshaft position sensor (B600) is an inductive sensor and is
fitted with a sensor coil as well as a permanent magnet.
Function
The permanent magnet on the camshaft position sensor (B600)
generates a magnetic field. Once the flywheel is rotated,
magnetic field fluctuations occur due to grooves in the flywheel
which are located, up to a gap of 18∞, 6∞ apart around the flywheel
circumference. Inductive voltage signals are generated in this way
in the crankshaft position sensor coil (B600) with the aid of which
the engine management (MCM) control unit (A4) can determine
the engine speed and, by using the gap of 18∞, the angular
position of the crankshaft.
