ECM
ECM (Engine Control Module) consists of CPU (Central Pro-
cessing Unit), memory (ROM/RAM) and IN/OUT section. Sig-
nals from various sensors are sent to the input section and then
to CPU. On the basis of information received, CPU performs cal-
culation of necessary amount of fuel injection by means of a
map that is programmed for various engine conditions and
sends operation signal from the output section to fuel injector.
Light load: When the engine load is light, the fuel injection time
(volume) is determined on the basis of intake air
pressure and engine speed.
High load: When the engine load is high, the fuel injection time
(volume) is determined on the basis of throttle valve
opening and engine speed.
ET SENSOR
ET (Engine Temperature) sensor sends the signal of engine
temperature as thermistor ohmic value, which is then detected
by ECM. When the engine temperature is low, the injection vol-
ume increases.
The thermistor ohmic value increases with the engine tempera-
ture low and it decreases with the temperature high.
TO SENSOR
TO (Tip-Over) sensor detects the vehicle inclination. When the
vehicle tips to more than 65°, a signal is sent to ECM. When this
signal continues for more than 2 seconds, ECM interrupts cur-
rent to fuel injector and ignition coil.
To restart the engine, turn the ignition switch OFF once and then
attempt starting in the normal procedure.
