Nissan Pathfinder (2007 year). Manual - part 262

PRECAUTIONS

GI-5

2007 Pathfinder

●

Use approved bonding agent, sealants or their equivalents when required.

●

Use hand tools, power tools (disassembly only) and recom-
mended special tools where specified for safe and efficient ser-
vice repairs.

●

When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.

●

Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.

WARNING:

To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.

Precautions for Three Way Catalyst

EAS001RK

If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.

●

Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.

●

When checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.

●

Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to
the catalyst.

Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.

Precautions for Fuel (Unleaded Premium Gasoline Recommended)

EAS001WR

Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
For improved vehicle performance, NISSAN/INFINITI recommend the use of unleaded premium gasoline with
an octane rating of at least 91 AKI number (Research octane number 96). E-85 fuel (85% fuel ethanol, 15%
unleaded gasoline) may only be used in vehicles specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle
- FFV models).

CAUTION:

Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.

PRECAUTIONS

2007 Pathfinder

Precautions for Multiport Fuel Injection System or Engine Control System

EAS001RM

●

Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.

●

Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.

●

Be careful not to jar components such as ECM and mass air
flow sensor.

Precautions for Hoses

EAS001RN

HOSE REMOVAL AND INSTALLATION

●

To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.

●

To reinstall the rubber hose securely, make sure of hose inser-
tion length and clamp orientation. (If tube is equipped with hose
stopper, insert rubber hose into tube until it butts up against
hose stopper.)

HOSE CLAMPING

●

If old rubber hose is re-used, install hose clamp in its original
position (at the indentation where the old clamp was). If there is
a trace of tube bulging left on the old rubber hose, align rubber
hose at that position.

●

Discard old clamps; replace with new ones.

PRECAUTIONS

GI-7

2007 Pathfinder

●

After installing leaf spring clamps, apply force to them in the
direction of the arrow, tightening rubber hose equally all around.

Precautions for Engine Oils

EAS001RO

Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.

HEALTH PROTECTION PRECAUTIONS

●

Avoid prolonged and repeated contact with oils, particularly used engine oils.

●

Wear protective clothing, including impervious gloves where practicable.

●

Do not put oily rags in pockets.

●

Avoid contaminating clothes, particularly underpants, with oil.

●

Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.

●

First aid treatment should be obtained immediately for open cuts and wounds.

●

Use barrier creams, applying them before each work period, to help the removal of oil from the skin.

●

Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepa-
rations containing lanolin replace the natural skin oils which have been removed.

●

Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.

●

If skin disorders develop, obtain medical advice without delay.

●

Where practical, degrease components prior to handling.

●

Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.

Precautions for Air Conditioning

EAS001RP

Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to

ATC-158, "HFC-134a (R-134a) Service Procedure"

for specific instructions.

How to Follow Trouble Diagnoses

EAS001RW

DESCRIPTION

NOTICE:
Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following
instructions before diagnosing.

Before performing trouble diagnoses, read the “Preliminary Check”, the “Symptom Chart” or the
“Work Flow”.

After repairs, re-check that the problem has been completely eliminated.

Refer to Component Parts and Harness Connector Location for the Systems described in each
section for identification/location of components and harness connectors.

Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness connectors in more detail, such as when a
sub-harness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG
section for identification of harness connectors.

When checking circuit continuity, ignition switch should be OFF.

Before checking voltage at connectors, check battery voltage.

After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure
that all harness connectors are reconnected as they were.
