(c) Do not a severe impact during removal or installation.
Handle all SFI parts carefully, especially the ECM.
(d) Be careful during the troubleshooting as there are numer-
ous transistor circuit, and even slight terminal contact can
cause further troubles.
(e) Do not open the ECM cover.
(f) When inspecting in rainy weather, take care to prevent
entry of water. Also, when washing the engine compart-
ment, prevent water from getting on the SFI parts and the
wiring connectors.
(g) Parts should be replaced as the original assembly.
(h) Care should be taken when pulling out and inserting the
wiring connectors.
(1) Release the lock and pull out the connector.
(2) Fully insert the connector and check that it is locked.
(i) Use SST for the inspection, the injector and the wiring
connector test.

8. FUEL SYSTEM
(a) When disconnecting the high fuel pressure line, a large
amount of gasoline may be spilled:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn the ignition switch OFF.
(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.

ON-VEHICLE INSPECTION
1. REMOVE V-BANK COVER
2. INSPECT SYSTEM OPERATION
(a) Inspect the throttle control motor for operating sound.
(1) Turn the ignition switch ON.
(2) When turning the accelerator pedal position sensor
lever, check the running sound of the motor. Also,
check that there is no friction sound.
If operation is not as specified, check the throttle control motor
(See step 3), wiring and ECM.
(b) Inspect the accelerator pedal position sensor.
(1) Connect the TOYOTA hand-held tester or OBD II
scan tool to the DLC3.
(2) Check that the MIL does not come on.
(3) When turning the accelerator pedal position sensor
lever to the full- open position, check that the
throttle valve opening percentage (THROTTLE
POS) of CURRENT DATA shows the standard val-
ue.
Standard throttle valve opening percentage:
60 % or more
If operation is not as specified, check that the accelerator pedal
position sensor (See page DI-318), wiring and ECM.
If you have no TOYOTA hand-held tester or OBD II scan tool,
measure the voltage between terminal VPA and E2 of the ECM
connector.
(c) Inspect the air assist system.
(1) Start the engine and check that the MIL does not
come on.
(2) Allow the engine to warm up to normal operating
temperature.
(3) Turn the A/C compressor ON to OFF, and check the
idle speed.

INSPECTION
1. INSPECT POWER SOURCE VOLTAGE OF VAPOR
PRESSURE SENSOR
(a) Disconnect the vapor pressure sensor connector.
(b) Turn the ignition switch ON.
(c) Using a voltmeter, measure the voltage between connec-
tor terminal 1 and 3 of the wiring harness side.
Voltage: 4.5 - 5.5 V
(d) Turn the ignition switch OFF.
(e) Reconnect the vapor pressure sensor connector.
2. INSPECT POWER OUTPUT OF VAPOR PRESSURE
SENSOR
(a) Turn the ignition switch ON.
(b) Remove the fuel tank cap.
(c) Connect a voltmeter to terminal 2 and 3, and measure the
output voltage.
Voltage: 3.0 - 3.6 V
(d) Reinstall the fuel tank cap.
(e) Turn the ignition switch OFF.

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.
HINT:
For step 2 to 6, refer to page BO-91.
1. INSTALL AIRBAG SENSOR ASSEMBLY
(a) Install the airbag sensor assembly with the 3 bolts.
Torque: 17.5 N´m (178 kgf´cm, 13 ft´lbf)
