Crankshaft Position Sensor: Description and Operation

The Crankshaft Position sensor (L5)
Crankshaft Position Sensor Location
The crankshaft position sensor (L5) registers the crankshaft position and engine speed. The position sensor is mounted to the crankcase above the
starter flange.
The sensor body projects through the crankcase very near to the segments on the flywheel/drive plate. There is no contact between the segments or the
position sensor.
Flywheel/drive Plate Segments
With the engine running, the two segments which are positioned 180° apart pass by the position sensor. Due to induction, an alternating voltage is
generated in the position sensor. The peak voltage is approx. 1.5 volts at starting speed. The voltage rises with increasing speed to approx. 3 volts at
1200 rpm.
