FUEL PRESSURE CHECK
1.
FUEL PRESSURE CHECK
CAUTION:
• Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
• The fuel hose connection method used when taking fuel pressure check must not be used for other
purposes.
• Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains seal ability with O-rings inside.
• Do not perform fuel pressure check with electrical systems operating (i.e. lights, rear defogger, A/C,
etc.) Fuel pressure gauge may indicate false readings due to varying engine load and changes in
manifold vacuum.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because F15 models do not have fuel return system.
1.
Release fuel pressure to zero.
2.
Prepare fuel hose for fuel pressure check (B) and fuel tube
adapter [SST (KV10118400) or (KV10120000)] (D), then con-
nect fuel pressure gauge (A).
CAUTION:
• Use suitable fuel hose for fuel pressure check (genuine
NISSAN fuel hose without quick connector).
• To avoid unnecessary force or tension to hose, use mod-
erately long fuel hose for fuel pressure check.
• Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
• Use Pressure Gauge to check fuel pressure.
3.
Remove fuel hose.
CAUTION:
Do not twist or kink fuel hose because it is plastic hose.

FUEL PRESSURE CHECK
4.
Connect fuel hose for fuel pressure check (1) to fuel tube
(engine side) with clamp (2) as shown in the figure.
CAUTION:
• Wipe off oil or dirt from hose insertion part using cloth
moistened with gasoline.
• Apply proper amount of gasoline between top of the fuel
tube (3) and No.1 spool (4).
• Insert fuel hose for fuel pressure check until it touches
the No.1 spool on fuel tube.
• Use NISSAN genuine hose clamp (part number: 16439
N4710 or 16439 40U00).
• When reconnecting fuel line, always use new clamps.
• Use a torque driver to tighten clamps.
• Install hose clamp to the position within 1 - 2 mm (0.04 - 0.08 in).
• Make sure that clamp screw does not contact adjacent parts.
5.
Connect fuel tube adapter to quick connector (1).
6.
After connecting fuel hose for fuel pressure check, pull the hose
with a force of approximately 98 N (10 kg, 22 lb) to confirm fuel
tube does not come off.
7.
Turn ignition switch ON and check for fuel leakage.
8.
Start engine and check for fuel leakage.
9.
Read the indication of fuel pressure gauge.
CAUTION:
• Do not perform fuel pressure check with system operat-
ing. Fuel pressure gauge may indicate false readings.
• During fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> GO TO 2.
2.
CHECK FUEL HOSE AND FUEL TUBE
If result is unsatisfactory, check fuel hoses and fuel tubes for clogging.
Is the inspection result normal?
YES
>> Replace “fuel filter and fuel pump assembly”.
NO
>> Repair or replace.

HOW TO SET SRT CODE
Description
INFOID:0000000006710149
OUTLINE
In order to set all SRTs, the self-diagnoses as in the “SRT ITEM” table must have been performed at least
once. Each diagnosis may require actual driving for a long period of time under various conditions.
SRT ITEM
The table below shows required self-diagnostic items to set the SRT to “CMPLT”.
*: Though displayed on the CONSULT-III screen, “HO2S HTR” is not SRT item.
SRT SERVICE PROCEDURE
If a vehicle has failed the state emissions inspection due to one or more SRT items indicating “INCMP”, review
the flowchart diagnostic sequence, referring to the following flowchart.

land keep it released for more than 10 seconds. Depress the accelerator pedal until vehicle speed is 90 km/h
(56 MPH) again.

HOW TO SET SRT CODE
Zone A refers to the range where the time, required for the diagnosis under normal conditions*, is the short-
est.
Zone B refers to the range where the diagnosis can still be performed if the diagnosis is not completed within
zone A.
*: Normal conditions refer to the following:
• Sea level
• Flat road
• Ambient air temperature: 20 - 30
°
C (68 - 86
°
F)
• Diagnosis is performed as quickly as possible under normal conditions.
Under different conditions [For example: ambient air temperature other than 20 - 30
°
C (68 - 86
°
F)], diagno-
sis may also be performed.

Description
INFOID:0000000006496264
The specification (SP) value indicates the tolerance of the value that is displayed in “SPEC” of “DATA MONI-
TOR” mode of CONSULT-III during normal operation of the Engine Control System. When the value in “SPEC”
of “DATA MONITOR” mode is within the SP value, the Engine Control System is confirmed OK. When the
value in “SPEC” of “DATA MONITOR” mode is NOT within the SP value, the Engine Control System may have
one or more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MI.
The SP value will be displayed for the following three items:
• B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correc-
tion)
• A/F ALPHA-B1 (The mean value of air-fuel ratio feedback correction factor per cycle)
