2020 NISSAN ALTIMA check engine light

Af termarket fuel additives
NISSAN does not recommend the use of
any af termarket fuel additives (for ex-
ample, fuel injector 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 sol-
vents 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 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, it is recom-
mended that you 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, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended 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

WARNING
A vehicle equipped with All -Wheel Drive
(AWD) should never be tested using a
two wheel dynamometer (such as the
dynamometers used by some states for
emissions testing), or similar equip-
ment. Make sure you inform the test fa-
cility personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious ve-
hicle damage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” 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 ve-
hicle.
If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready” condi-
tion. Before taking the I/M test, check the vehicle’s inspection/maintenance test
readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds , the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.
This vehicle is equipped with an EDR. The
main purpose of an EDR is to record, in
certain collision or near collision-like situa-
tions, such as an air bag deployment or
hitting a road obstacle, data that will assist
in understanding 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 passen- ger safety belts were buckled/fastened;
∙ How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
∙ How fast the vehicle was traveling.
∙ Sounds are not recorded.
These data can help provide a better un-
derstanding of the circumstances in which
collisions and injuries occur. NOTE: EDR
data are recorded by your vehicle only if a
nontrivial collision situation occurs; no data
are recorded by the EDR under normal driv-
ing conditions and no personal data (e.g.
name, gender, age and collision location)
