ENGINE LUBRICATION -General Information12-2
GENERAL INFORMATION
The lubrication method is a fully force-fed, full-flow
filtration type. The oil pump is a gear type which
is driven by the crankshaft via the timing belt.

Health Warning
Prolonged and repeated contact with mineral oil
will result in the removal of natural fats from the
skin, leading to dryness, irritation and dermatitis.
In addition, used engine oil contains potentiallyharmful contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must be provided.
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example
by using enclosed systems for handling used engine
oil and by degreasing components, where
practicable, before handling them.
Other precautions:
DAvoid prolonged and repeated contact with oils,
particularly used engine oils.
DWear protective clothing, including impervious
gloves where practicable.
DAvoid contaminating clothes, particularly
underpants, with oil.
DDo not put oily rags in pockets, the use of
overalls without pockets will avoid this.
DDo not wear heavily soiled clothing and
oil - impregnated foot - wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.DWhere there is a risk of eye contact, eye
protection should be worn, for example,
chemical goggles or face shields; in addition
an eye wash facility should be provided.
DObtain First Aid treatment immediately for open
cuts and wounds.
DWash regularly with soap and water to ensure
all oil is removed, especially before meals (skin
cleansers and nail brushes will help). After
cleaning, the application of preparations
containing lanolin to replace the natural skin
oils is advised.
DDo not use petrol, kerosine, diesel fuel, gas
oil, thinners or solvents for cleaning skin.
DUse barrier creams, applying them before each
work period, to help the removal of oil from
the skin after work.
DIf skin disorders develop, obtain medical advice
without delay.

temperature of the coolant reaches 80_Cto90_C.
2. Remove the engine oil filler cap.
3. Remove the drain plug to drain oil.
Caution
Use care as oil could be hot.
4. Remove the under cover.
5. Use the respective tool in the following table to remove
the engine oil filter.
6. Clean the filter bracket side mounting surface.
7. Apply a small amount of engine oil to the O-ring of the new
oil filter.
8. Once the O-ring of the oil filter is touching the flange,
use the generic tool to turn for approximately 3/4 round
and tighten to (14±2 N·m).
9. Install the drain plug and refill the engine oil.
(Refer to Engine Oil Replacement P.12-4.)
10. Race the engine 2 - 3 times, and check to be sure that
no engine oil leaks from installation section of the oil
filter.
OIL PRESSURE CHECK
1. Check engine oil quantity.
2. Remove the oil pressure switch terminal.
3. Use the special tool (oil pressure switch wrench) to remove
the oil pressure switch.
Caution
Since sealant is applied to the thread of oil pressure
switch, take care not to damage the oil pressure switch
when removing it.

4. Install the oil pressure gauge.
NOTE
Use a adapter of PT 1/8 thread.
5. Run the engine to warm it.
6. After the engine has been warmed up, check that oil
pressure is within the standard value.
Standard value:
At idle: 29 kPa or more
At 3,500 r/min: 294 - 686 kPa
7. Remove the oil pressure gauge.
8. Apply the specified sealant to the thread of oil pressure
switch.
Specified sealant: 3M ATD Part No. 8660 or equivalent
9. Use the special tool to tighten the oil pressure switch
to the specified torque.
Tightening torque: 10±2 N·m
Caution
Do not start the engine within one hour after the oil
pressure switch has been installed.

MPI -General Information13A-3
GENERAL INFORMATION
The Multipoint Fuel Injection System consists
of sensors which detect the engine conditions,
the engine-ECU which controls the system
based on signals from these sensors, and
actuators which operate under the control of
the engine-ECU. The engine-ECU carries outactivities such as fuel injection control, idle
speed control and ignition timing control. In
addition, the engine-ECU is equipped with
several diagnosis modes which simplify
troubleshooting when a problem develops.
FUEL INJECTION CONTROL
The injector drive times and injector timing are
controlled so that the optimum air/fuel mixture
is supplied to the engine to correspond to the
continually-changing engine operation condi-
tions.
A single injector is mounted at the intake port
of each cylinder. Fuel is sent under pressure
from the fuel tank by the fuel pump, with the
pressure being regulated by the fuel pressure
regulator. The fuel thus regulated is distributed
to each of the injectors.
Fuel injection is normally carried out once for
each cylinder for every two rotations of the
crankshaft. The firing order is 1-3-4-2. This iscalled sequential fuel injection. The
engine-ECU provides a richer air/fuel mixture
by carrying out “open-loop” control when the
engine is cold or operating under high load
conditions in order to maintain engine
performance. In addition, when the engine is
warm or operating under normal conditions,
the engine-ECU controls the air/fuel mixture
by using the oxygen sensor signal to carry out
“closed-loop” control in order to obtain the
theoretical air/fuel mixture ratio that provides
the maximum cleaning performance from the
three way catalyst.
IDLE AIR CONTROL
The idle speed is kept at the optimum speed
by controlling the amount of air that bypasses
the throttle valve in accordance with changes
in idling conditions and engine load during
idling. The engine-ECU drives the idle speed
control motor to keep the engine running at
the pre-set idle target speed in accordance
with the engine coolant temperature and airconditioner load. In addition, when the air
conditioner switch is turned off and on while
the engine is idling, the idle speed control motor
operates to adjust the throttle valve bypass
air amount in accordance with the engine load
conditions in order to avoid fluctuations in the
engine speed.
IGNITION TIMING CONTROL
The power transistor located in the ignition
primary circuit turns ON and OFF to control
the primary current flow to the ignition coil. This
controls the ignition timing in order to provide
the optimum ignition timing with respect to theengine operating conditions. The ignition timing
is determined by the engine-ECU from the
engine speed, intake air volume, engine coolant
temperature and barometric pressure.
SELF-DIAGNOSIS FUNCTION
DWhen an abnormality is detected in one
of the sensors or actuators related to
emission control, the engine warning lamp
(check engine lamp) illuminates as a
warning to the driver.
DWhen an abnormality is detected in one
of the sensors or actuators, a diagnosis
code corresponding to the abnormality is
output.DThe RAM data inside the engine-ECU that
is related to the sensors and actuators can
be read by means of the MUT-II. In addition,
the actuators can be force-driven under
certain circumstances.
