FUEL INJECTOR AND FUEL TUBE
• Do not reuse O-rings.
• Upper and lower O-rings are different. Be careful not to confuse them.
• Handle O-ring with bare hands. Do not wear gloves.
• Lubricate O-ring with new engine oil.
• Do not clean O-ring with solvent.
• Check that O-ring and its mating pa rt are free of foreign material.
• When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretc hed while it was being attached, do not insert it
quickly into fuel tube.
• Insert O-ring straight into fu el injector. Do not twist it.
3. Install fuel injector to fuel tube as follows:
a. Insert clip (3) into clip groove (F) on fuel injector (5).
• Insert clip so that protrusion (E ) of fuel injector matches cutout
(C) of clip.
CAUTION:
• Do not reuse O-rings.
• Do not reuse clip. Replace it with new one.
• Be careful to keep clip from interfering with O-ring. If interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube (1) with clip attached. • Insert it while matching it to the axial center.
• Insert fuel injector so that protrusion (A) of fuel tube matches
cutout (B) of clip.
• Check that fuel tube flange (G) is securely fixed in flange fixing
groove (D) on clip.
c. Check that installation is complete by checking that fuel injector does not rotate or come off.
• Check that protrusions of fuel injectors and fuel tubes are
aligned with cutouts of clips after installation.
4. Install fuel tube and fuel injector assembly to intake manifold. CAUTION:
Be careful not to let tip of injector nozzle come in contact with other parts.
• Tighten bolts in two steps in numerical order as shown.
5. Connect fuel injector harness.
6. Install intake manifold collector. Refer to EM-146, "Removal and Installation"
.
7. Connect quick connector between fuel feed hose and fuel tube connection with the following procedure:
a. Check no foreign substances are deposited in and around fuel tube and quick connector, and no damage on them.Fuel tube side : Black
Nozzle side : Green

b. Thinly apply new engine oil around fuel tube from tip end to spool end.
c. Align center to insert quick connector straightly into fuel tube. • Insert quick connector (1) to fuel tube until top spool (2) is
completely inside quick connector, and 2nd level spool (3)
exposes right below quick connector.
CAUTION:
• Do not reuse O-ring.
• Hold (A) position as shown when inserting fuel tube into quick connector.
• Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
• Insert until you hear a “click” sound and actually feel the engagement.
• To avoid misidentification of enga gement with a similar sound, be sure to perform the next step.
d. Pull quick connector by hand holding position. Check it is completely engaged (connected) so that it does
not come out from fuel tube.
e. Install quick connector cap (3) to quick connector.
• Install quick connector cap with arrow (A) on surface facing indirection of quick connector (fuel feed hose side).
CAUTION:
If quick connector cap cannot be installed smoothly, quick
connector may have not been installed correctly. Check
connection again.
f. Secure fuel feed hose to clamp of quick connector cap.
8. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections as follows:
1. Apply fuel pressure to fuel lines by turning i gnition switch ON (with engine stopped). Then check for fuel
leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections. WARNING:
Do not touch engine immediately after stopping as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
• Perform procedures for “Throttle Valve Closed Position Learning” after finishing repairs. Refer to EC-
682, "Work Procedure".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-683, "Work Procedure"
.

• Before starting engine, check oil/fluid levels incl
uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubricants"
.
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner dr ops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

Inspection after InstallationINFOID:0000000009460570
INSPECTION OF CAMSHAFT SPROCKET (INT) OIL GROOVE
WARNING:
• Check when engine is cold so as to pr event burns from any splashing engine oil.
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT and
it is directed according to inspection procedure of EC section. Refer to EC-716, "Diagnosis Proce-
dure".

End cranking after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing control solenoid valve installation hole during cranking. Use a
shop cloth to prevent engi ne oil from splashing on
worker, engine components and vehicle.

as drive belts or engine mount insulators. I mmediately wipe off any splashed engine oil.
5. Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from intake valve timing control solenoid valve cover oil hole.
6. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary.
7. After inspection, installation of the remaining components is in the reverse order of removal.
