MIXTURE RATIO FEEDBACK CONTROL
The mixture ratio feedback system provides the best air-fuel
mixture ratio for driveability and emission control. The three way
catalyst can then better reduce CO, HC and NOx emissions. This
system uses a heated oxygen sensor in the exhaust manifold to
monitor if the engine is rich or lean. The ECM adjusts the injec-
tion pulse width according to the sensor voltage signal. For more
information about heated oxygen sensor, refer to page EC-123.
This maintains the mixture ratio within the range of stoichiomet-
ric (ideal air-fuel mixture).
This stage is referred to as the closed loop control condition.
OPEN LOOP CONTROL
The open loop system condition refers to when the ECM detects
any of the following conditions. Feedback control stops in order
to maintain stabilized fuel combustion.
lDeceleration and acceleration
lHigh-load, high-speed operation
lEngine idling
lMalfunction of heated oxygen sensor or its circuit
lInsufficient activation of heated oxygen sensor at low engine
coolant temperature
lHigh-engine coolant temperature
lDuring warm-up
lWhen starting the engine
MIXTURE RATIO SELF-LEARNING CONTROL
The mixture ratio feedback control system monitors the mixture
ratio signal transmitted from the heated oxygen sensor. This
feedback signal is then sent to the ECM. The ECM controls the
basic mixture ratio as close to the theoretical mixture ratio as
possible. However, the basic mixture ratio is not necessarily con-
trolled as originally designed. Both Manufacturing differences
(i.e. mass air flow sensor hot wire) and characteristic changes
during operation (i.e. injector clogging) directly affect mixture
ratio.
Accordingly, the difference between the basic and theoretical
mixture ratios is monitored in this system. This is then computed
in terms of ``injection pulse duration'' to automatically compen-
sate for the difference between the two ratios.
FUEL INJECTION SYSTEM
Two types of systems are used.
Sequential multiport fuel injection system
Fuel is injected into each cylinder during each engine cycle
according to the firing order. This system is used when the
engine is running.

pump

Ignition switchcStart signal
The ECM activates the fuel pump for several sec-
onds after the ignition switch is turned on to
improve engine startability. If the ECM receives a
180É signal from the camshaft position sensor, it
knows that the engine is rotating, and causes the
pump to operate. If the 180É signal is not received
when the ignition switch is on, the engine stalls.
The ECM stops pump operation and prevents bat-
tery discharging, thereby improving safety. The
ECM does not directly drive the fuel pump. It con-
trols the ON/OFF fuel pump relay, which in turn
controls the fuel pump.Condition Fuel pump operation

TROUBLE DIAGNOSIS FOR NON-DETECTABLE ITEMSKA

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine
compartment side without removing the headlamp body.
lGrasp only the plastic base when handling the bulb.
Never touch the glass envelope.
1. Disconnect the battery cable.
2. Disconnect the harness connector from the back side of the
bulb.
3. Pull off the rubber cap.
4. Push and raise retaining pin to loosen it.
5. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
6. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp reflector without bulb for a long
period of time. Dust, moisture, smoke, etc. entering head-
lamp body may affect the performance of the headlamp.
Remove headlamp bulb from the headlamp reflector just
before a replacement bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should
be in good repair, calibrated and operated in accordance with
respective operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is no-load in vehicle (coolant, engine oil
filled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ``0'' when performing aiming
adjustment on vehicles equipped with headlamp aiming
control.

DIESEL ENGINE*:
For Europe: diesel fuel of above 50 cetane
* If two types of diesel fuel are available, use summer or win-
ter fuel properly according to the following temperature con-
ditions.
lAbove þ7ÉC (20ÉF) ... Summer type diesel fuel.
lBelow þ7ÉC (20ÉF) ... Winter type diesel fuel.
CAUTION:
lDo not use home heating oil, gasoline, or other alternate
fuels in your diesel engine. The use of those can cause
engine damage.
lDo not use summer fuel at temperature below þ7ÉC
(20ÉF). The cold temperature will cause wax to form in
the fuel. As a result, it may prevent the engine from run-
ning smoothly.
lDo not add gasoline or other alternate fuels to diesel
fuel.
Precautions for Air Conditioning
Use an approved refrigerant recovery unit any time the air con-
ditioning system must be discharged. Refer to HA section
(``HFC-134a (R-134a) Service Procedure'', ``SERVICE PRO-
CEDURES'') for specific instructions.

Depending on annual driving distance and engine types, different basic schedules are introduced here.
Please follow the appropriate schedule for the vehicle. Furthermore, according to the weather and atmo-
spheric conditions, varying road surfaces, individual driving habits and vehicle usage, additional or more
frequent maintenance may be required, as shown in ``Maintenance Under Severe Driving Conditions''.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
