FUEL PRESSURE

Connect fuel hose for fuel pressure check (1) to high pressure
fuel pump 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 high

pressure fuel pump (3) and spool (4).

• Insert fuel hose for fuel pressure check until it touches

the spool on high pressure fuel pump.

• 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.
• 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.

Connect fuel tube adapter to quick connector.

Turn ignition switch ON and check for fuel leakage.

Start engine and check for fuel leakage.

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

CHECK FUEL HOSES

Check the following.

Fuel hoses for clogging

Fuel filter for clogging

Low pressure fuel pump

Fuel pressure regulator for clogging

Is the inspection result normal?

YES

>> Replace fuel pressure regulator.

>> Repair or replace error-detected parts.

Tightening torque:

1 - 1.5 N·m (0.1 - 0.15 kg-m, 9 - 13 in-lb)

HOW TO SET SRT CODE

Description

INFOID:0000000009753140

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”.

*1: Though displayed on the CONSULT screen, “HO2S HTR” is not SRT item.
*2: If completion of several SRTs is required, perform driving patterns (DTC confirmation procedure), one by
one based on the priority for models with CONSULT.

HOW TO SET SRT CODE

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.

[MR16DDT ]

Always drive the vehicle in safe manner according to traffic conditions and obey all traffic laws.

*1: Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH), then release the accelerator pedal
and keep it released for more than 10 seconds. Depress the accelerator pedal until vehicle speed is 90 km/h
(56 MPH) again.
*2: Checking the vehicle speed with GST is advised.
• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving

habits, etc.

• “Zone A” is the fastest time where required for the diagnosis under normal conditions*. If the diagnosis is not

completed within “Zone A”, the diagnosis can still be performed within “Zone B”.

OUTLINE

When a DTC is stored in ECM

When a DTC is stored in ECM and MIL is ON, a permanent DTC is erased with MIL shutoff if the same mal-
function is not detected after performing the driving pattern for MIL shutoff three times in a raw.

When a DTC is not stored in ECM

The erasing method depends on a permanent DTC stored in ECM. Refer to the following table.

: Applicable —: Not applicable

*: For group, refer to

EC-101, "DTC Index"

PERMANENT DTC ITEM

For permanent DTC items, MIL turns ON. Refer to

EC-101, "DTC Index"

*1:

When the same malfunction is de-
tected in two consecutive trips, MIL
will illuminate.

*2:

MIL will turn off after vehicle is driven
3 times (driving pattern B) without
any malfunctions.

TROUBLE DIAGNOSIS - SPECIFICATION VALUE

Description

INFOID:0000000009753146

The specification (SP) value indicates the tolerance of the value that is displayed in “SPEC” of “DATA MONI-
TOR” mode of CONSULT 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
MIL.
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)
• MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)

Make sure that all of the following conditions are satisfied.
• Vehicle driven distance: More than 5,000 km (3,107 miles)
• Barometric pressure: 98.3 - 104.3 kPa (1.003 - 1.064 kg/cm

• Atmospheric temperature: 20 - 30

C (68 - 86

• Engine coolant temperature: 75 - 95

C (167 - 203

• Transmission: Warmed-up
- CVT models: After the engine is warmed up to normal operating temperature, drive vehicle until “FLUID

TEMP SE” (CVT fluid temperature sensor signal) indicates more than 60

C (140

F).

- M/T models: After the engine is warmed up to normal operating temperature, drive vehicle for 5 minutes.
• Electrical load: Not applied
- Rear window defogger switch, air conditioner switch, lighting switch are OFF. Steering wheel is straight

ahead.
