ENGINE AND EMISSION CONTROL SYSTEM 6E1-5
AIR INTAKE SYSTEM
The main components of the air intake system are air cleaner (1), air cleaner outlet hose (2), throttle body (3),
idle air control valve (4) and intake manifold (5).
The air (by the amount corresponding to the throttle valve (6) opening and engine speed) is filtered by the air
cleaner (1), passes through the throttle body (3), is distributed by the intake manifold (5) and finally drawn into
each combustion chamber.
When the idle air control valve (4) is opened according to the signal from ECM, the air (7) bypasses the throttle
valve (6) through bypass passage and is finally drawn into the intake manifold (5).

ENGINE AND EMISSION CONTROL SYSTEM 6E1-7
ELECTRONIC CONTROL SYSTEM
The electronic control system consists of 1) various sensors which detect the state of engine and driving condi-
tions, 2) ECM which controls various devices according to the signals from the sensors and 3) various controlled
devices.
Functionally, it is divided into nine sub systems :
Fuel injection control system
Idle speed control system
Fuel pump control system
A/C control system (if equipped)
Radiator fan control system
EGR system (if equipped)
Evaporative emission control system
Oxygen sensor heater control system (if equipped)
Ignition control system
Also, with A/T model, ECM sends throttle valve opening signal and coolant temp. signal to transmission control
module to control A/T.
