check engine NISSAN SENTRA 1997 B14 / 4.G Owner's Guide

Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself operations'' section.
Emission control system
maintenance
Drive belts* ÐCheck drive belts for wear,
fraying or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter ÐUnder normal driving
conditions, the air cleaner filter should be
replaced in accordance with the maintenance
schedule. However, driving the vehicle in
dusty areas may cause more rapid clogging
of the element. Consequently, the element
may have to be replaced more frequently.
Vapor lines ÐCheck vapor lines and con-
nections for failure or looseness. If leaks are
found, replace them.
Fuel lines ÐCheck the fuel hoses, piping
and connections for leaks, looseness or
deterioration. Replace any parts if they are
damaged.
Fuel filter ÐIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-
ther extremely low or extremely high, thefilter might become clogged. In such an
event, replace the filter immediately.
Engine coolant* ÐDrain and flush the
cooling system.
Engine oil & oil filter* ÐUnder normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.
Spark plugs* ÐReplace with new plugs
having the correct heat range.
Intake & exhaust valve clearance Ð
Check and adjust the valve clearance.
Chassis and body maintenance
Brake lines & cables ÐCheck the brake
lines and hoses (including brake booster
vacuum hoses, connections & check valve)
and parking brake cables for proper attach-
ment, leaks, cracks, chafing, abrasion, de-
terioration, etc.
Brake pads, discs, drums & linings Ð
Check these and the other neighboring brake
components for wear, deterioration and
leaks. Under severe driving conditions, they
may have to be inspected more frequently.
Manual & automatic transmission fluid*
ÐCheck the fluid level and visually inspect
for signs of leakage.
Under severe driving conditions, the fluid
should be replaced at the specified interval.
Steering gear & linkage, axle & suspen-
sion parts, and drive shaft boots Ð
Check for damage, looseness and leakage
of oil or grease. Under severe driving con-
ditions, more frequent inspection should be
performed.
Steering linkage ball joints & front sus-
pension ball joints ÐCheck the ball joints
for damage, looseness and grease leakage.
Exhaust system ÐVisually check the ex-
haust pipes, muffler, and hangers for proper
attachment, leaks, cracks, chafing, abra-
sion, deterioration, etc. Under severe
driving conditions, inspection should be per-
formed more frequently.
Supplemental air bag system (if so
equipped) ÐCheck the supplemental air
bag system components for proper attach-
ment, damage, deformities, cracks, rust,
etc. Work around and on the supplemental
air bag system should be done by an autho-
rized NISSAN dealer.

of at least 87 AKI (Anti-Knock Index). How-
ever, you may use unleaded gasoline with
an octane rating as low as 85 AKI (Anti-
Knock Index) in high altitude areas (over
4,000 ft [1,219 m]) such as: Colorado, Mon-
tana, New Mexico, Utah, Wyoming, north-
eastern Nevada, southern Idaho, western
South Dakota, western Nebraska, and that
part of Texas which is directly south of New
Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ``spark knock.'' (``Spark
knock'' is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady
speed on level roads, have your dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.
Incorrect ignition timing results in knocking,
after-run and/or overheating. This in turn
may cause excessive fuel consumption or
damage to the engine. If any of the above
symptoms are encountered, have your ve-hicle checked at a NISSAN dealer or other
competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
not a cause for concern, because you
get the greatest fuel benefit when there
is light spark knock for a short time
under heavy engine load.
