INSTALLATION
NOTICE:
Never use SRS parts from another vehicle. When re-
placing parts, replace them with new parts.
Never reuse the airbag sensor assembly involved in
a collision when the airbag has deployed.
Never repair a sensor in order to reuse it.
1. INSTALL AIRBAG SENSOR ASSEMBLY
(a) Using a torx wrench, install the airbag sensor assembly
with 4 screws.
Torx wrench: T40 (Part No.09042-00020 or locally
manufactured tool)
Torque: 21 N´m (210 kgf´cm, 15 ft´lbf)
(b) Connect the airbag sensor connectors.
NOTICE:
Installation of the connector is done after the sensor
assembly has been installed.
Make sure the sensor assembly is installed with the
specified torque.
If the sensor assembly has been dropped, or there are
cracks, dents or other defects in the case, bracket or
connector, replace the sensor assembly with a new
one.
When installing the senor assembly, take care that
the SRS wiring does not interfere with other parts and
is not pinched between other parts.
After installing , shake the sensor assembly to check
that there is no looseness.
2. INSTALL THESE PARTS:
(a) Console box
(b) Parking brake hole cover
(c) Console panel upper

PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM, DISCON-
NECT NEGATIVE (-) TERMINAL CABLE FROM BAT-
TERY.
HINT:
Any diagnostic trouble code retained by the computer will be
erased when the negative (-) terminal cable is removed from
the battery.
Therefore, if necessary, read the diagnosis before removing the
terminal.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME
WHEN WORKING ON FUEL SYSTEM.
3. KEEP GASOLINE AWAY FROM RUBBER OR LEATH-
ER PARTS.
4. MAINTENANCE PRECAUTIONS
(a) In event of engine misfire, following precautions should
be taken.
(1) Check proper connection of battery terminals, etc.
(2) After repair work, check that the ignition coil termi-
nals and all other ignition system lines are recon-
nected securely.
(3) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Precautions when handling oxygen sensor.
(1) Do not allow oxygen sensor to drop or hit against an
object.
(2) Do not allow the sensor to come into contact with
water.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RADIO SYS-
TEM (HAM, CB, ETC)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Separation of the engine oil dipstick, oil filler cap, PCV
hose, etc. may cause the engine to run out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will allow air suction and cause the engine to run out
of tune.
7. ELECTRONIC CONTROL SYSTEM
(a) Before removing SFI wiring connectors, terminals, etc.,
first disconnect the power by either turning the ignition
switch OFF or disconnecting the negative (-) terminal
cable from the battery.
HINT:
Always check the diagnostic trouble code before disconnecting
the negative (-) terminal cable from the battery.

(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative (-) cables.
(c) Do not permit parts to receive a severe impact during re-
moval or installation. Handle all SFI parts carefully, espe-
cially the ECM.
(d) Do not be careless during troubleshooting as there are
numerous transistor circuits and even slight terminal con-
tact can further troubles.
(e) Do not open the ECM cover.
(f) When inspecting during rainy weather, take care to pre-
vent entry of water. Also, when washing the engine
compartment, prevent water from getting on the SFI parts
and wiring connectors.
(g) Parts should be replaced as an assembly.
(h) Care is required when pulling out and inserting wiring con-
nectors.
(1) Release the lock and pull out the connector, pulling
on the connectors.
(2) Fully insert the connector and check that it is locked.
(i) When inspecting a connector with a volt/ohmmeter
(1) Carefully take out the water-proofing rubber if it is
a water-proof type connector.
(2) Insert the test probe into the connector from the wir-
ing side when checking the continuity, amperage or
voltage.
(3) Do not apply unnecessary force to the terminal.
(4) After checking, install the water-proofing rubber on
the connector securely.
(j) Use SST for inspection or test of the injector or its wiring
connector.
SST 09842-30060
8. FUEL SYSTEM
(a) When disconnecting the high pressure fuel line, a large
amount of gasoline will spill out, so observe the following
procedures:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn off the ignition switch.

(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with a rubber plug.
(7) Reconnect the fuel pump connector.
(b) When connecting the flare nut or union bolt on the high
pressure pipe union, observe the following procedures:
(1) Union Bolt Type:
Always use a new gasket.
(2) Union Bolt Type:
Tighten the union bolt by hand.
(3) Union Bolt Type:
Tighten the union bolt to the specified torque.
Torque: 29 N´m (300 kgf´cm, 22 ft´lbf)
(4) Flare Nut Type:
Apply a light coat of engine oil to the flare nut and
tighten the flare nut by hand.
(5) Flare Nut Type:
Using SST, tighten the flare nut to the specified
torque.
SST 09631-22020
Torque: 30 N´m (310 kgf´cm, 22 ft´lbf)
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
(c) Observe the following precautions when removing and
installing the injectors.
(1) Never reuse the O-ring.
(2) When placing a new O-ring on the injector, take
care not to damage it in any way.
(3) Coat a new O-ring with spindle oil or gasoline be-
fore installing-never use engine, gear or brake oil.
(d) Install the injector to the delivery pipe and intake manifold
as shown in the illustration.

(e) Check that there are no fuel leaks after doing mainte-
nance anywhere on the fuel system.
(1) Connect the TOYOTA hand- held tester to the
DLC3.
(2) Turn the ignition switch ON and TOYOTA hand-
held tester main switch ON.
NOTICE:
Do not start the engine.
(3) Select the active test mode on the TOYOTA hand-
held tester.
(4) Please refer to the TOYOTA hand-held tester oper-
ator 's manual for further details.
(5) If you have no TOYOTA hand-held tester, connect
the positive (+) and negative (-) leads from the bat-
tery to the fuel pump connector.
(See page SF-5)
(6) Pinch the fuel return hose.
The pressure in the high pressure line will rise to
approx. 392 kPa (4 kgf/cm
2, 57 psi). In this state,
check to see that there are no leaks from any part
of the fuel system.
NOTICE:
Always pinch the hose.
Avoid bending as it may cause the hose to crack.
(7) Turn the ignition switch to LOCK.
(8) Disconnect the TOYOTA hand-held tester from the
DLC3.
