ON±VEHICLE INSPECTION
1. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(a) With the engine running or cranking, use a sound scope
to check that there is a normal operating noise in propor-
tion to engine speed.
(b) If you have no sound scope, you can check the injector
transmission operation with your finger.
If no sound or unusual sound is heard, check the wiring connec-
tor, injector or injection signal from the ECM.
2. 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.

(k) If you have no TOYOTA hand±held tester, connect the
positive (+) and negative (±) leads from the battery to the
fuel pump connector. (See page SF±6)
(l) Connect SST (wire) to the injector and battery for 15 se-
conds, and measure the injection volume with a gra-
duated cylinder. Test each injector 2 or 3 times.

Volume: 51 ± 63 cm
3 (3.2 ± 3.8 cu in.) per 15 seconds
Difference between each injector:
12 cm
3 (0.7 cu in.) or less
If the injection volume is not as specified, replace the injector.
2. INSPECT LEAKAGE
(a) In the condition above, disconnect the tester probes of
SST (wire) from the battery and check the fuel leakage
from the injector.
SST 09842±30070
Fuel drop: 1 drop or less per 3 minutes
(b) Turn the ignition switch OFF.
(c) Disconnect the negative (±) terminal cable from the bat-
tery.
(d) Remove the SST.
SST 09268±41047, 09842±30070
(e) Disconnect the TOYOTA hand±held tester from the
DLC3.
(f) Reconnect the fuel inlet hose to the fuel filter outlet with
2 new gaskets and the union bolt.

install them to each injector.
(d) Except California:
Apply a light coat of gasoline onto a new O±ring, and
install it to each injector.

(l) Tighten the 2 bolts holding the delivery pipe to the cylinder
head.
Torque: 13 N´m (130 kgf´cm, 9 ft´lbf)
(m) Connect the 4 injector connectors.
HINT:
The No.1 and No.3 injector connectors are brown, and the No.2
and No.4 injector connectors are gray.
2. INSTALL CYLINDER HEAD COVER
(a) Install the cylinder head cover. (See page EM±53)
(b) Connect the PCV hose to the intake manifold.
(c) Connect the PCV hose to the cylinder head cover.
(d) Install the engine wire clamp to the mounting bolt of the
No.2 timing belt cover.
(e) Connect the 4 high±tension cords to the spark plugs.
(f) Install the 4 high±tension cords to the clamps on the cylin-
der head cover.

INSPECTION
INSPECT FUEL TANK AND LINE
(a) Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.
(b) Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leakage
or tank band looseness.
