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-
forming circuit.Therotor plate has360slits fora1

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.

*2: •The "OVERALL FUNCTIONCHECK"isasimplified andeffective waytoinspect acomponent orcircuit.
In some cases, the"OVERALL FUNCTIONCHECK"isused rather thana"DIAGNOSTIC TROUBLECODECONFIRMA-
TION PROCEDURE".
When noDTC CONFIRMATION PROCEDUREisavailable, the"NG" result ofthe OVERALL FUNCTION CHECKcanbe
considered tomean thesame asaDTC detection .
• During an"NG" OVERALL FUNCTION CHECK,theDTC might notbeconfirmed.
