(e) Install the injector to the delivery pipe and lower intake
manifold as shown in the illustration.
Before installing the injector, spindle oil or gasoline must
be applied on the place where the delivery pipe or the in-
take manifold touches the O-ring of the injector.
(f) Take following precautions to disconnect the fuel tube
connector (quick type):
(1) Check that there is no dirt on the pipe and around
the connector before disconnecting them. If there
is, clean the dirt away.
(2) Be sure to disconnect it with hands.
(3) Type A:
When the connector and the pipe are stuck, push
the clicks of the retainer and pull the connector to
free to disconnect and pull it out. Do not use any tool
at this time.
Type B:
When the connector and the pipe are stuck, turn
and pull the connector to disconnect. Do not use
any tool at this time.
(4) Inspect if there is any dirt or the likes on the seal sur-
face of the disconnected pipe and clean it away.
(5) Prevent the disconnected pipe and connector from
damaging and getting foreign objects by covering
them with a vinyl bag.
(g) Take following precautions to connect the fuel tube con-
nector (quick type):
(1) Do not reuse the retainer removed from the pipe.
(2) Do not use any tool. Use hands to connect the re-
tainer to the pipe.
(3) Check if there is any damage or foreign objects on
the connected part of the pipe.

(4) Match the axis of the connector with that of the pipe,
and push in the connector until the connector
makes a ºclickº sound. In the joint part is too tight to
connect them, apply a little new engine oil on the tip
of the pipe.
(5) After finishing the connection, check if the pipe and
the connector are securely connected by pulling
them.
(6) Check if there is any fuel leakage.
(h) Take following precautions to handle the nylon tube.
(1) Pay attention not to turn the joint part of the nylon
tube and the quick connector by force when con-
necting them.
(2) Pay attention not to twist the nylon tube.
(3) Do not remove the EPDM protector on the outside
of the nylon tube.
(4) Do not connect them by bending the nylon tube.
(i) Check that there are no fuel leaks on the fuel system after
doing the maintenance.
(1) Connect the TOYOTA hand-held tester or OBD II
scan tool to the DLC3.
(2) Turn the ignition switch ON and press the TOYOTA
hand-held or OBD II scan tool tester main switch
ON.
NOTICE:
Do not start the engine.
(3) Select the ACTIVE TEST mode on the TOYOTA
hand-held tester or OBD II scan tool .
(4) Please refer to the TOYOTA hand-held tester or
OBD II scan tool operator's manual for further de-
tails.
(5) If you have no TOYOTA hand-held tester or OBD
II scan tool, connect the positive (+) and negative
(-) leads from the battery to the fuel pump connec-
tor (See page SF-7).

(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 is no leak on any part of the
fuel system.
NOTICE:
Always pinch the hose. Do not bend as it may cause the
hose to crack.
(7) Turn the ignition switch OFF.
(8) Disconnect the TOYOTA hand-held tester from the
DLC3.

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.
