3. Select the bearing from the above table according to
the identification confirmed in steps 1 and 2.
[Example of selecting bearing]
(1) If the measured outer diameter of the crankshaft
journal is 57.000 mm, Class 1 applies, and the
identification colour is yellow.
(2) If the cylinder block bearing bore identification mark
is 0, select identification mark 0 in consideration of
step (1).
4. Install the grooved bearing on the cylinder block side.
5. Install the bearing with no oil groove onto the beam bearing
cap side.

INSTALLATION
1. Install the beam bearing cap with the arrow facing the
timing belt side.
2. Before installing the bearing cap bolt, confirm that the
bolt’s underhead length is less than the limit value.
Replace the bolt if it exceeds the limit value.
Limit value: 71.1 mm
3. Apply engine oil on the bolt threads and bolt surface.
4. Following the tightening order, tighten the bearing cap
bolt at 25±2N•m.
5. Make paint marks on the bolt head.
6. Using the position of the mark painted on the bolt head
as reference, make paint marks on the seat surface at
the 90_to 100_positions in the tightening direction.
7. Following the tightening order, tighten the bolt by 90_
to 100_, and confirm that the paint marks made on the
bolt and seat surface match.
Caution
(1) If the tightening angle is less than 90_, the
connection performance may not be attained, so
take special care when tightening.
(2) If the tightening angle exceeds 100_, completely
loosen the nut, and start again from step 1.Crankshaft bearing side

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.
ENGINE OILS
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.

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.

MPI -TroubleshootingMPI -Troubleshooting13A-11
CONFIRMING FREEZE FRAME DATA
When the engine-ECU detects a malfunction and stores a diagnosis code, it also stores a current status
of the engine. This function is called “Freeze frame” data. By analyzing this “Freeze frame” data with
MUT-II, an effective troubleshooting can be performed.
NOTE
If mulfunctions have been detected in multiple systems, engine-ECU stores one malfunction only, which
has been detected first.

FAIL-SAFE FUNCTION REFERENCE TABLE
When the main sensor malfunctions are detected by the diagnosis function, the vehicle is controlled
by means of the pre-set control logic to maintain safe conditions for driving.
Malfunctioning itemControl contents during malfunction
Air flow sensor1. Uses the throttle position sensor signal and engine speed signal (crank angle sensor
signal) to take reading of the basic injector drive time and basic ignition timing from
the pre-set mapping.
2. Fixes the idle speed control servo in the appointed position so idle control is not
performed.

sensorControls as if the intake air temperature is 25_C.
Throttle position
sensorNo increase in fuel injection amount during acceleration due to the throttle position sensor
signal.
Engine coolant
temperature sensor1. Controls as if the engine coolant temperature is 80_C.

is set to the “LOCK” (OFF) position.)
2. Rotates radiator fan and condenser fan at high speed.
Camshaft position

centre is not detected at all after the ignition switch is turned to “ON” position.)
2. Shuts off fuel supply after 4 seconds have passed since a failure was detected.
(However, when the No.1 cylinder top dead centre is not detected at all after the
ignition switch is turned to “ON” position.)
Barometric pressure
sensorControls as if the barometric pressure is 101 kPa.
Detonation sensorSwitches the ignition timing from ignition timing for super petrol to ignition timing for standard
petrol.
