Camshaft
PositionSensor(CMPS)

The camshaft positionsensorisabasic component ofthe
EGGS. Itmonitors enginespeedandpiston position. These
input signals tothe EGM areused tocontrol fuelinjection, igni-
tion timing andother functions.
The camshaft positionsensorhasarotor plate andawave-

signal. Thewave-forming circuitconsists ofLight Emitting
Diodes (LED)andphoto diodes.
The rotor plate ispositioned' betweentheLED andthephoto
diode. TheLED transmits lighttothe photo diode. Asthe rotor
plate turns, theslits cutthe light togenerate rough-shaped
pulses. Thesepulses areconverted intoon-off signals bythe
wave-forming circuitandsent tothe EGM.
