2021 NISSAN MAXIMA check engine

Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting ad-
ditive. NISSAN does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMT
content, not all do, so you may have to
consult your gasoline retailer for more
details.
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.

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
vehicle.
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.
