Function
The permanent magnet on the camshaft position sensor (B601)
generates a magnetic field. When the camshaft rotates,
fluctuations in the magnetic field occur due to the grooves in the
camshaft sprocket. These changes in the magnetic field are
converted by the electronic analysis system in the camshaft
position sensor (B601) into shift signals and passed on to the
engine management (MCM) control unit (A4).
