2016 NISSAN TITAN check engine

CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the
engine. Failure to do so could lead to an
oil leak and engine damage.7. Fill the new filter with clean engine oil.
8. Coat the gasket on the new filter with clean engine oil.
9. Screw on the oil filter until a slight resistance is felt, then tighten an additional 3/4 turn.
10. Start the engine and check for leakage around the oil filter. Correct as required.
11. Install skid plate in reverse order of removal.
12. Turn the engine off and wait more than 10 minutes. Check the oil level. Add engine
oil if necessary.
CAUTION
Your vehicle may require more frequent
maintenance if it operates on biodiesel
blends between 6% and 10% (B6 and B10) .
To avoid damage to your vehicle, the oil,
oil filter, and fuel filter will need to be
replaced after a shorter time interval than
if your vehicle was operating on pure
petroleum-based diesel. For additional in-
formation, refer to the “Maintenance” sec-
tion in the “Titan Owner’s Manual.”
FUEL FILTER REPLACEMENT (stage
1)
NOTE:
● It is possible the “Low Fuel Pressure
Service Fuel System” message will dis-
play on the vehicle information display
after fuel filter replacement due to air
being introduced into the fuel system.

FUEL FILTER REPLACEMENT (stage
2)
NOTE:● It is possible the “Low Fuel Pressure
Service Fuel System” message will dis-
play on the vehicle information display
after fuel filter replacement due to air
being introduced into the fuel system. ●
If the “Low Fuel Pressure Service Fuel
System” message is displayed on the
vehicle information display with the
engine running, complete a full key
cycle and restart the vehicle. If the mes-
sage is still displayed or the Malfunc-
tion Indicator Light is illuminated after
a full key cycle , it is recommended that
you visit a NISSAN dealer for service.
● For additional information on the loca-
tion of the fuel filter (stage 2) , refer to
the “Engine compartment check loca-
tions” in this section.
WARNING
● The fuel system (fuel pump, high pres-
sure fuel lines, fuel rail, injectors) con-
tain very high pressure fuel. To avoid the
risk of personal injury or fire;
– Do not loosen any fittings while the engine is running.
– Wait at least 10 minutes after shut- ting down the engine before loosen-
ing any fittings in the high-pressure
fuel system to allow pressure to de-
crease to a lower level. – Wear appropriate eye protection and
protective equipment as high-
pressure fuel spray can penetrate the
skin.
– Never smoke or allow sparks or flames (such as pilot lights, electrical
switches, or welding equipment) in
the work area. Never allow diesel fuel
to spill onto a hot exhaust manifold
which can cause a fire.
● Batteries can emit explosive gases. To
reduce the possibility of personal injury,
always ventilate the compartment be-
fore servicing the batteries. To reduce
the possibility of arcing, remove the
negative (-) battery cable first and at-
tach the negative (-) battery cable last.
● When using a steam cleaner, wear
safety glasses or a face shield, as well
as protective clothing. Hot steam can
cause serious personal injury.
● Wear appropriate eye and face protec-
tion when using compressed air. Flying
debris and dirt can cause personal
injury.

AUTOMATIC REGENERATION
Automatic regeneration occurs when the control
module detects the exhaust filter needs to be
cleaned. This is a normal process and will not
typically require any operator interaction.
If the automatic regeneration is not able to clean
the exhaust filter the vehicle information display
will display the following messages in order of
severity:● Exhaust Filter Overloaded See Owners
Manual for Drive Pattern
● Exhaust Filter Overloaded Engine Power
Reduced See Owners Manual for
● Exhaust Filter Overloaded Immediate Ser-
vice Required
The instructions for these messages in the “Me-
ters and Gauges” section of this manual will
inform the driver to modify their driving pattern to
enable the automatic regeneration process.

WARNING
To avoid the risk of personal injury, be
sure the ignition switch is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly.
1. Visually inspect the belt for signs of unusual wear, cuts, fraying or looseness. If the belt is
in poor condition or is loose, have it re-
placed. It is recommended you visit a
NISSAN dealer for this service.
2. Have the belt checked regularly for condi- tion and tension in accordance with the
maintenance schedule found in the “Titan
Owner’s Manual”.
