FUEL INJECTOR AND FUEL TUBE
c. Align center to insert quick connector straight onto fuel tube.
d. Insert fuel tube into quick connector (1) until the top spool (B) on fuel tubes is inserted completely and the second level spool (C)
is positioned slightly below the quick connector bottom end.
CAUTION:
• Hold at position (A) as show n, when inserting the fuel
tube into the quick connector.
• Carefully align to center to avoid inclined insertion to pre-
vent damage to the O-ring inside the quick connector.
• Insert the fuel tube until you hear a “click” sound and
actually feel the engagement.
• To avoid misidentification of engagement with a similar
sound, be sure to perform the next step.
• Do not reuse O-ring.
e. Before clamping the fuel hose with the hose clamp, pull the quick connector hard by hand, holding at the
(A) position, as shown. Make sure it is completely engaged (connected) so that it does not come off of the
fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
f. Install quick connector cap (1) over fuel hose side (B) and fuel tube side (A).
NOTE:
Direct arrow mark on quick connector cap (1) to fuel hose side.
5. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at connections as follows:
1. Apply fuel pressure to fuel lines by turning ignition 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. • Perform procedures for “Throttle Valve Closed Posi tion Learning” after finishing repairs. Refer to EC-
178, "Work Procedure".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-179, "Work Procedure"
.
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.

WARNING:
Check when engine is cold so as to preven t burns from any splashing engine oil.
CAUTION:
Perform this inspection only when DTC P0011, P0014, P052A, P052B is detected in self-diagnostic
results of CONSULT and it is directed according to inspection procedure of EC section. Refer to EC-
210, "Diagnosis Procedure".
1. Check engine oil level and adjust oil level as necessary. Refer to LU-9, "Inspection"
.
2. Remove the intake valve timing intermediate lock control solenoid valve, intake valve timing control sole- noid valve, and exhaust valve timing control solenoid valve. Refer to EM-58, "Intake Valve Timing Interme-
diate Lock Control Solenoid Valve, Intake Valve Timing Control Solenoid Valve, and Exhaust Valve Timing
Control Solenoid Valve".
3. Perform the following procedure to prevent the engi ne from being unintentionally started while checking.

pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing intermedi-
ate lock control solenoid valve, intake valve timing control
solenoid valve, exhaust valve timing control solenoid
valve installation holes during cranking. Use a shop cloth
to prevent engine oil from splashing on worker, engine
components and vehicle.
• Do not allow engine oil to get on rubber componen ts such as drive belts or engine mount insula-
tors. Immediately wipe off any splashed engine oil.
5. If engine oil does not come out from valve timing cont rol cover oil holes (A), diagnose problem in lubrica-
tion circuit such as dirty oil groove between oil strainer and intake valve timing intermediate lock control
solenoid valve, intake valve timing control solenoid valve, or exhaust valve timing control solenoid valve.
Refer to LU-7, "Lubrication Circuit"
.
a. Remove components between intake valve timing intermediate lock control solenoid valve, intake valve timing control solenoid valve, exhaust valve timing c ontrol solenoid valve and camshaft sprocket (INT) or
camshaft sprocket (EXH), (if necessary) and then check each oil groove for clogging.
b. Clean oil groove if necessary. Refer to LU-7, "Lubrication Circuit"
.

PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951676
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three mi nutes before performing any service.
Precaution for Draining CoolantINFOID:0000000009460515
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000009460516
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000009460517
• When instructed to use special service tools, use the spec ified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equiva lent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specif ied, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000009460518
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000009460519
• Use torque wrench to tighten bolts or nuts to specification.

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:
