2014 NISSAN SENTRA check engine light

Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimes Make sure all
warning lights and chimes are operating properly.
Windshield wiper and washer* Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defroster Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner (if so equipped) .
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* Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles 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
chargers, 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 fluid levels*
Make sure that
the brake and clutch fluid level is 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 10 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 by a NISSAN dealer. See the carbon monoxide warning 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 (if so equipped) after use is nor-
mal. If you should notice any leaks or if gasoline
fumes are evident, check for the cause and have
it corrected immediately.
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.
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. See
the “Appearance and care” section of this
manual.
Windshield-washer fluid* Check that there is
adequate fluid in the reservoir.
8-4Maintenance and do-it-yourself

CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and applythe parking brake.
2. Turn the engine off.
3. Place a large drain pan under the oil filter
C.
4. Loosen the oil filter with an oil filter wrench by turning it counterclockwise. Then remove
the oil filter by turning it by hand.
CAUTION
Be careful not to burn yourself. The engine
oil may be hot. 5. Wipe the engine oil filter sealing surface with
a clean rag.
CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the
engine. Failure to do so could lead to
engine damage.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw on the oil filter until a slight resistance is felt, then tighten an additional 2/3 turn.
8. Start the engine and check for leakage around the oil filter. Correct as required.
9. Turn the engine off and wait more than 10 minutes. Check the oil level. Add engine
oil if necessary.
CAUTION
●Use only Genuine NISSAN CVT Fluid
NS-3. Do not mix with other fluids.
● Using transmission fluid other than
Genuine NISSAN CVT Fluid NS-3 will
damage the CVT, which is not covered
by the warranty.
When checking or replacement of CVT fluid is
required, we recommend your NISSAN dealer for
servicing.

Maintenance and do-it-yourself8-11

If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front (and rear– if so equipped) disc-type
brakes self-adjust every time the brake pedal is
applied. The rear drum-type brakes (if so
equipped) self-adjust every time the parking
brake is applied.
WARNING
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect the
function or performance of the brake system.
Proper brake inspection intervals should
be followed.
For more information regarding
brake inspections, see the appropriate mainte-
nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.
Two types of fuses are used. Type
Ais used in
the fuse boxes in the engine compartment. Type
Bis used in the passenger compartment fuse
box.
Type A fuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type A fuses can be installed in the engine com-
partment and passenger compartment fuse
boxes.

BRAKES FUSES
Maintenance and do-it-yourself8-21

If a type A fuse is used to replace a type B fuse,
the type A fuse will not be level with the fuse
pocket as shown in the illustration. This will not
affect the performance of the fuse. Make sure the
fuse is installed in the fuse box securely.
Type B fuses cannot be installed in the under-
hood fuse boxes. Only use type A fuses in the
underhood fuse boxes.ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower
amperage rating than specified on the
fuse box cover. This could damage the
electrical system or cause a fire.
If any electrical equipment does not come on,
check for an open fuse. 1. Be sure the ignition switch and the headlight switch are OFF.
2. Open the engine hood. 3. Remove the fuse box cover by pushing the
tab
Aand lifting the cover up.
4. Remove the fuse with the fuse puller, which is located in the center of the fuse block in
the passenger compartment.

8-22Maintenance and do-it-yourself

●If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol) . It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not avail-
able to ensure that all methanol blends
are suitable for use in NISSAN ve-
hicles.
If any driveability problems such as engine stall-
ing and difficult hot-starting are experienced after
using oxygenate-blend fuels, immediately
change to a non-oxygenate fuel or a fuel with a
low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
E–15 fuel
E-15 fuel is a mixture of approximately 15% fuel
ethanol and 85% unleaded gasoline. E-15 can
only be used in vehicles designed to run on E-15
fuel. Do not use E-15 in your vehicle. U.S. gov-
ernment regulations require fuel ethanol dispens-
ing pumps to be identified with small, square, orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
E–85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square, orange
and black label with the common abbreviation or
the appropriate percentage for that region.
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 youdetect 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 a NISSAN dealer correct the
condition. Failure to correct the condition
is misuse of the vehicle, for which NISSAN
is not responsible.
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 at a
NISSAN dealer.
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.
Technical and consumer information9-5

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”. Contact 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.
