FORM-IN-PLACE-GASKET
FIPG is used for several members of this engine. With this gasket, caution is required to the application
amount, application procedure and state of the application surface so that the performance is sufficiently
attained.
If sufficient gasket is not applied, leaks could occur, and if too much is applied, the gasket could protrude
and plug or restrict the oil and water flow passage. Thus, to prevent leaks from the joined sections,
it is absolutely necessary to evenly apply the correct amount.
The FIPG used for the engine parts reacts with moisture in the air and hardens so use it for the normal
metal flange parts.
DISASSEMBLY
The parts assembled with FIPG can be easily disassembled without special means. However, in some
cases, the sealant on the seams must be broken by lightly tapping with a wood hammer or similar tool.
A smooth and thin gasket scraper can be lightly tapped into the seams but in this case, take care not
to damage the seams.
The special tool oil pan remover (MD998727) is set for this purpose.
WASHING THE GASKET SURFACE
Completely remove all matters adhered on the gasket surfaces with a gasket scraper or wire brush.
Confirm that the FIPG application surface is smooth. There must be no grease or foreign matter on
the gasket surface.
Always remove the old FIPG that has entered the mounting holes and screw holes.
APPLICATION PROCEDURES
Apply an even coat of FIPG within the predetermined radius. Completely cover the areas around the
mounting holes. The FIPG can be wiped off if it has not hardened. Install at the set position while the
FIPG is still wet (within 15 minutes). When installing, maker sure that the FIPG does not get on areas
other than the required areas. After installing, do not subject the application areas to oil or water or
start the engine until the FIPG has sufficiently hardened (approx. one hour). The FIPG application procedures
differ according to the member, so follow the procedures given in this manual and apply the FIPG.

NOTE
SAE 5W-30 can be only used at the area where the
lowest temperature is lower than the applicable
temperature of SAE 5W-30.
6. Install the engine oil filler cap.
7. Check oil level.

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

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.

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.
