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 following sub systems:
D Fuel injection control system
D Idle speed control system
INFORMATION SENSORS
1. MAP sensor
2. TP sensor
3. IAT sensor
4. ECT sensor
5. Heated oxygen sensor-1
6. VSS
7. Ignition coil
8. Battery
9. Distributor (CMP sensor)
10. Fuel level sensor (gauge) (in fuel tank)
11. CKP sensor
12. CTP switch (in ISC actuator)
13. Heated oxygen sensor-2
14. Stop lamp switch
15. A / C EVAP temp. sensor (if equipped)
ENGINE AND EMISSION CONTROL SYSTEM 6E1-5
D Fuel pump control system
D A/C control system (if equipped)
D Radiator fan control system
D Evaporative emission control system
D EFE heater control system
D Oxygen sensor heater control system
D Ignition control system
