ENGINE AND EMISSION CONTROL SYSTEM
6E1-5
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
according to the signals from the sensors and 3) vari-
ous controlled devices.
Functionally, it is divided into the following sub sys-
tems:
Fuel injection control system
Idle speed control system
Fuel pump control system
Ignition control system
Radiator fan control system
Evaporative emission control system
A / C control system (if equipped)
INFORMATION SENSORS
1. MAP sensor
2. TP sensor
3. IAT sensor
4. ECT sensor
5. Oxygen sensor
6. VSS
7. Battery
8. CMP sensor
9. Blank
10. A/C evaporator temp. sensor (if equipped)
11. A/C dual pressure switch (if equipped)
