ELECTRONIC CONTROL SYSTEM
The electronic control system consists of 1) various
sensors which detect the state of engine and driving
conditions, 2) ECM which controls various devices ac-
cording to the signals from the sensors and 3) various
controlled devices.
Functionally, it is divided into the following sub sys-
tems:
Main relay control system
Fuel injection control system
Idle air control system
Fuel pump control system
Evaporative emission control system
Ignition control system
EGR system (if equipped)
Heated oxygen sensor heater control system (if
equipped)
1. CO adjusting resistor (if equipped)
