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 the following sub systems:
Fuel injection control system
Idle speed control system
Fuel pump control system
A/C control system (if equipped)
A/C condenser fan control system
EGR system (if equipped)
Evaporative emission control system
Oxygen sensor heater control system
Ignition control system
Also, with A/T model, ECM sends throttle valve opening signal and over drive cut signal to transmission control
module to control A/T.
NOTE:
The figure shows left-hand steering vehicle. For right-hand steering vehicle, parts with (*) are installed
at the other side.

Fuel Delivery System
Fuel pressure inspection
1) Relieve fuel pressure in fuel feed line referring to “Fuel Pres-
sure Relief Procedure” in Section 6.
2) Disconnect fuel feed hose from fuel delivery pipe.
3) Connect special tools and hose between fuel delivery pipe
(1) and fuel feed hose (2) as shown in figure, and clamp
hoses securely to ensure no leaks occur during checking.
Special tool
(A) : 09912-58442
(B) : 09912-58432
(C) : 09912-58490
4) Check that battery voltage is above 11 V.
5) Turn ignition switch ON to operate fuel pump and after 2 sec-
onds turn it OFF. Repeat this 3 or 4 times and then check
fuel pressure.
Fuel pressure specification WARNING:
Be sure to perform work in a well-ventilated area and
away from any open flames, or there is a risk of a fire
breaking out.
CAUTION:
A small amount of fuel may be released when fuel hose is
disconnected. Place container under the joint with a
shop cloth so that released fuel is caught in container or
absorbed in cloth. Place that cloth in an approved con-
tainer.
3. Fuel return pipe
CONDITION FUEL PRESSURE
With fuel pump operating and
engine stopped270 – 310 kPa
2.7 – 3.1 kg/cm

38.4 – 44.0 psi
At specified idle speed 210 – 260 kPa

29.8 – 37.0 psi
With 1 min. after engine (fuel
pump) stop (Pressure
reduces as time passes)over 200 kPa

3) Fuel pressure should be felt at fuel feed hose (1) for 2 sec-
onds after ignition switch ON.
If fuel pressure is not felt, advance to “Diagnostic Flow Table
B-3” in Section 6.
REMOVAL
Remove fuel tank from body according to procedure described in
“Fuel Tank” of Section 6C and remove fuel pump from fuel tank.
INSPECTION
Check fuel pump filter for evidence of dirt and contamination. If
present, clean and check for presence of dirt in fuel tank.
INSTALLATION
1) Install fuel pump to its bracket.
2) Install fuel pump to fuel tank and then install fuel tank to
body according to procedure described in “Fuel Tank” of
Section 6C.
Fuel pressure regulator
ON-VEHICLE INSPECTION
Perform fuel pressure inspection according to procedure
described in “Fuel Pressure Inspection” of this section.
REMOVAL
1) Relieve fuel pressure according to procedure described on
“Fuel Pressure Relief Procedure” in Section 6.
2) Disconnect battery negative cable from battery.
3) Disconnect vacuum hose (1) from fuel pressure regulator
(2).
4) Remove fuel pressure regulator from fuel delivery pipe.
5) Disconnect fuel return hose (3) from fuel pressure regulator.
CAUTION:
A small amount of fuel may be released when it is from
delivery pipe.
Place a shop cloth under delivery pipe so that released
fuel is absorbed in it.

REMOVAL
1) Disconnect battery negative cable at battery.
2) Disable air bag system, refer to “Disabling Air Bag System”
in Section 10B if equipped.
3) Remove glove box.
4) Disconnect ECM (1) and TCM (3) (if equipped) connectors.
5) Loosen 2 nuts (2) and remove ECM and TCM (if equipped).
INSTALLATION
1) Reverse removal procedure noting the following:
Connect connectors to ECM and TCM (if equipped)
securely.
Manifold absolute pressure sensor (MAP sensor)
INSPECTION
Check MAP sensor referring to “MAP Sensor Individual Check” in
DTC P0105 (No.11) Flow Table of Section 6. If malfunction is
found, replace.CAUTION:
As ECM consists of precision parts, be careful not to
expose it to excessive shock.
