2017 NISSAN SENTRA check engine

Seat belts:Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheel: Check for changes in the
steering system, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and that
the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery* (for serviceable batteries): Check
the fluid level in each cell. It should be between
the MAX and MIN lines. Vehicles operated in high
temperatures or under severe conditions require
frequent checks of the battery fluid level. NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, GPS, DVD players, etc.) .
2. Vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake and clutch (if so equipped) fluid
level*: Make sure that the brake and clutch fluid
levels are between the MIN and MAX lines on the
reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belts*: Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 15 minutes for the oil to drain
back into the oil pan. Exhaust system:
Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected. It is recommended that you
visit a NISSAN dealer for this service. For addi-
tional information, refer to “Exhaust gas (carbon
monoxide)” in the “Starting and driving” section of
this manual.
Fluid leaks: Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if fuel fumes are evident,
check for the cause and have it corrected imme-
diately.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
9-4Maintenance and schedules

Underbody:The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. For
additional information, refer to the “Appearance
and care” section of this manual.
Windshield-washer fluid*: Check that there is
adequate fluid in the reservoir. The following descriptions are provided to give
you a better understanding of the scheduled
maintenance items that should be regularly
checked or replaced. The maintenance schedule
indicates at which mileage/time intervals each
item requires service.
In addition to scheduled maintenance, your vehicle
requires that some items be checked during normal
day-to-day operation. For additional information,
refer to “General maintenance” in this section.
Items marked with
“*”are recommended by
NISSAN for reliable vehicle operation. You are
not required to perform maintenance on these
items in order to maintain the warranties which
come with your NISSAN. Other maintenance
items and intervals are required.
When applicable, additional information can be
found in the “Do-it-yourself” section of this
manual.
NOTE:
NISSAN does not advocate the use of non-
OEM approved aftermarket flushing sys-
tems and strongly advises against perform-
ing these services on a NISSAN product.
Many of the aftermarket flushing systems
use non-OEM approved chemicals or sol-
vents, the use of which has not been vali-
dated by NISSAN. For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to “Recom-
mended fluids/lubricants and capacities”
in the “Technical and consumer informa-
tion” section of this manual.
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive belts*:
Check engine drive belts for wear,
fraying or cracking and for proper tension. Re-
place any damaged drive belts.
Engine air filter: Replace at specified intervals.
When driving for prolonged periods in dusty con-
ditions, check/replace the filter more frequently.
Engine coolant*: Replace coolant at the speci-
fied interval. When adding or replacing coolant,
be sure to use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent with the
proper mixture. (For additional information on the
proper mixture for your area, refer to “Engine
cooling system” in the “Do-it-yourself” section of
this manual.)
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.
EXPLANATION OF SCHEDULED
MAINTENANCE ITEMS
Maintenance and schedules9-5

Engine oil and oil filter:Replace engine oil
and oil filter at the specified intervals. For recom-
mended oil grade and viscosity refer to “Recom-
mended fluids/lubricants and capacities” in the
“Technical and consumer information” section of
this manual.
Engine valve clearance*: Inspect only if valve
noise increases. Adjust valve clearance if neces-
sary.
Evaporative emissions control vapor lines*:
Check vapor lines for leaks or looseness. Tighten
connections or replace parts as necessary.
Fuel filter: Periodic maintenance is not re-
quired. (in-tank type filter)
Fuel lines*: Check the fuel hoses, piping and
connections for leaks, looseness, or deteriora-
tion. Tighten connections or replace parts as
necessary.
Spark plugs: Replace at specified intervals. In-
stall new plugs of the type as originally equipped.CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing, cracks,
deterioration, and signs of leaking. Replace any
deteriorated or damaged parts immediately.
Brake pads, rotors, drums and linings:
Check for wear, deterioration and fluid leaks.
Replace any deteriorated or damaged parts im-
mediately.
Exhaust system: Visually inspect the exhaust
pipes, muffler and hangers for leaks, cracks, de-
terioration, and damage. Tighten connections or
replace parts as necessary.
In-cabin microfilter: Replace at specified in-
tervals. When driving for prolonged periods in
dusty conditions, replace the filter more fre-
quently.
Steering gear and linkage, axle and sus-
pension parts, drive shaft boots: Check for
damage, looseness, and leakage of oil or grease.
Under severe driving conditions, inspect more
frequently. Tire rotation:
Tires should be rotated every
5,000 miles (8,000 km) according to the instruc-
tions under “General maintenance” in this sec-
tion. When rotating tires, check for damage and
uneven wear. Replace if necessary.
Transmission fluid/oil: Visually inspect for
signs of leakage at specified intervals. If using a
car-top carrier, or driving on rough or muddy
roads:
● Replace the manual transaxle gear oil every
20,000 miles or 24 months.
● Replace the CVT fluid every 60,000 miles
(96,000 km) or request the dealer to inspect
the fluid deterioration data using a CON-
SULT. If the deterioration data is more than
210000, replace the CVT fluid.
9-6Maintenance and schedules

Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor cleaner, octane booster, intake valve deposit
removers, etc.) which are sold commercially.
Many of these additives intended for gum, varnish
or deposit removal may contain active solvents or
similar ingredients that can be harmful to the fuel
system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, 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, it is recommended that you have a
NISSAN dealer correct the condition. Fail-
ure to correct the condition is misuse of the
vehicle, for which NISSAN is not respon-
sible.Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked. It is rec-
ommended that you visit a NISSAN dealer for
servicing.
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.
10-6Technical and consumer information

Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” for an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition” when it
is driven through certain driving patterns. Usually,
the ready condition can be obtained by ordinary
usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready” condition. Before taking the
I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Place the ignition switch in the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20 sec-
onds and then blinks for 10 seconds , the I/M test
condition is “not ready”. If the MIL does not blink
after 20 seconds, the I/M test condition is
“ready”. It is recommended that you visit a
NISSAN dealer to set the “ready condition” or to
prepare the vehicle for testing.This vehicle is equipped with an Event Data Re-
corder (EDR) . The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an air bag deployment or hitting a
road obstacle, data that will assist in understand-
ing how a vehicle’s systems performed. The EDR
is designed to record data related to vehicle
dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
● How various systems in your vehicle were
operating;
● Whether or not the driver and passenger
safety belts were buckled/fastened;
● How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
● How fast the vehicle was traveling.
● Sounds are not recorded. These data can help provide a better understand-
ing of the circumstances in which crashes and
injuries occur. NOTE: EDR data are recorded by
your vehicle only if a nontrivial crash situation
occurs; no data are recorded by the EDR under
normal driving conditions and no personal data
(e.g. name, gender, age and crash location) are
recorded. However, other parties, such as law
enforcement, could combine the EDR data with
the type of personally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR, special equip-
ment is required and access to the vehicle or the
EDR is needed. In addition to the vehicle manu-
facturer and NISSAN dealer, other parties, such
as law enforcement, that have the special equip-
ment, can read the information if they have ac-
cess to the vehicle or the EDR. EDR data will only
be accessed with the consent of the vehicle
owner or lessee or as otherwise required or per-
mitted by law.
