This system switches thesolenoid timeronand offcorresponding tothe engine coolant temperature and
engine speed.Thesolenoid timeroperation advancesandretards thefuel injection timingasfollows:
• The injection timingadvances whenthetimer isON, while itretards whenthetimer isOFF.
• When theengine stallsorthe ignition switchisin the START position, thesolenoid timerisset to

DESCRIPTION
Solenoid timer

The solenoid timerswitches onand offinaccordance witha
signal fromtheECM. Thistimer operation changesthepres-
sure inthe injection pump,thereby controlling thefuel injection
timing.

Engine speedsensor

The engine speedsensor detects enginespeedbymonitoring
the rotation ofdrive shaftgearinthe injection pump.Thesen-
sor sends asignal of37 pulses perdrive shaftrotation tothe
