ON±VEHICLE INSPECTION
1. REMOVE V±BANK COVER
(a) Using a 5 mm hexagon wrench, remove the 2 cap nuts.
(b) Disconnect the 2 clips, and remove the V±bank cover.
2. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(1) With the engine running or cranking, use a sound
scope to check that there is normal operating noise
in proportion to engine speed.
(2) If you have no sound scope, you can check the in-
jector operating vibration with your finger.
If no sound or unusual sound is heard, check the wiring connec-
tor, injector or injection signal from the ECM.
3. INSPECT INJECTOR RESISTANCE
(a) Disconnect the injector connector.
(b) Using an ohmmeter, measure the resistance between the
terminals.
Resistance: 13.4 ± 14.2 W at 20°C (68°F)
If the resistance is not as specified, replace the injector.
(c) Reconnect the injector connector.
4. REINSTALL V±BANK COVER
HINT:
For fixing the V±bank cover, push on the cover until a ºclickº is
felt.

REMOVAL
1. REMOVE AIR CLEANER HOSE
2. REMOVE AIR INTAKE CHAMBER ASSEMBLY
(See page EM±32)
3. DISCONNECT INJECTOR CONNECTORS
4. REMOVE AIR ASSIST HOSES AND PIPE
(a) Disconnect the air assist pipe from the bracket on the
No.1 fuel pipe.
(b) Remove the air assist hoses from the intake manifold.
5. DISCONNECT NO.1 FUEL PIPE
(a) Remove the fuel hose clamp.
(b) Disconnect the No.1 fuel pipe (fuel tube connector) from
the fuel filter outlet.
CAUTION:
Perform disconnecting operations of the fuel tube
connector (quick type) after observing the precau-
tions. (See page SF±1)
As there is retained pressure in the fuel pipe line, pre-
vent it from splashing inside the engine compart-
ment.

6. REMOVE DELIVERY PIPES AND INJECTORS
NOTICE:
Be careful not to drop the injectors when removing
the delivery pipes.
Pay attention to put any hung load on the injector to
and from the side direction.
(a) Remove the 5 bolts and delivery pipes together with the
6 injectors and No.1 fuel pipe.
(b) Remove the 4 spacers from the intake manifold.
(c) Pull out the 6 injectors from the delivery pipes.
(d) Remove the 2 O±rings and 2 grommets from each injec-
tor.

INSPECTION
1. INSPECT INJECTOR INJECTION
CAUTION:
Keep injector clear of sparks during the test.
(a) Purchase the new No.1 fuel pipe and take out the fuel
tube connector from its pipe.
Part No. 23801±20041
(b) Connect SST (hose ) and fuel tube connector to the fuel
filter outlet.
SST 09268±41047
CAUTION:
Preform connecting operations of the fuel tube connector
(quick type) after observing the precautions.
(See page SF±1)
HINT:
Use the vehicle fuel filter.

(e) Put the injector into a graduated cylinder.
HINT:
Install a suitable vinyl hose onto the injector to prevent gasoline
from splashing out.
(f) Connect a TOYOTA hand±held tester to the DLC3.
(g) Turn the ignition switch ON and push the TOYOTA hand±
held tester main switch ON.
NOTICE:
Do not start the engine.
(h) Select the ACTIVE TEST mode on the TOYOTA hand±
held tester.
(i) Please refer to the TOYOTA hand±held tester operator's
manual for further details.
