engine HONDA PILOT 2005 1.G Repair Manual

Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure light. If it does not go out
within ten seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving.
(Seeon page
).
Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning lights.
This indicator should never
come on when the engine is
running. If it starts f lashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible and you should
take immediate action.
Go to a service station or garage
where you can get technical
assistance. Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.

Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn of f
the engine as soon as you can saf ely get
the vehicle stopped.

If your vehicle battery has been
disconnected or gone dead, these
codes are erased. It takes at least
three days of driving under various
conditions to set the codes again.
If the malf unction indicator lamp
comes on along with the ‘‘D’’
indicator, there is a problem in the
automatic transmission control
system.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If the indicator remains on or the
f uel cap was not loose or missing,
have the vehicle checked by the
dealer as soon as possible. If you have recently ref ueled your
vehicle, the cause of this indicator
coming on could be a loose or
missing f uel f ill cap. Check the cap
or replace it. Tightening the cap will
not make the indicator turn of f
immediately; it takes at least three
days of normal driving. If this indicator comes on
while driving, it means one
of the engine’s emission control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance,
continued operation may cause
serious damage. To check if they are set, turn the
ignition to ON (II), without starting
the engine. The malf unction
indicator lamp will come on f or 20
seconds. If it then goes of f , the
readiness codes are set. If it blinks
f ive times, the readiness codes are
not set. If possible, do not take your
vehicle f or a state emissions test
until the readiness codes are set.
Refer to
f or more inf ormation (see page ).

damage your vehicle’s emission
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

Your vehicle has several identif ying
numbers in various places.
The vehicle identif ication number
(VIN) is the 17-digit number your
dealer uses to register your vehicle
f or warranty purposes. It is also
necessary f or licensing and insuring
your vehicle. The easiest place to
find the VIN is on a plate fastened to
the top of the dashboard. You can
seeitbylookingthroughthe
windshield on the driver’s side. It is
also on the certification label
attached to the driver’s doorjamb,
and is stamped on the engine
compartment bulkhead. The VIN is
also provided in bar code on the
certif ication label.

ÎÎIn Canada, Honda vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, at the time they are
manuf actured.
Your vehicle has a positive
crankcase ventilation system. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The positive crankcase ventilation valve routes
them from the crankcase back to the
intake manif old. They are then
drawn into the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The onboard ref ueling vapor
recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
The burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx) and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas.
The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page

The exhaust emissions controls
include f our systems: PGM-FI,
ignition timing control, exhaust gas
recirculation and three way catalytic
converter. These f our systems work
together to control the engine’s
combustion and minimize the
amount of HC, CO, and NOx that
comes out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.
The PGM-FI system uses sequential
multiport f uel injection.
It has three subsystems: air intake,
engine control, and f uel control. The
powertrain control module (PCM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
f uel to inject under all operating
conditions.The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual f or more informa-
tion.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor. This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manif old. Adding exhaust gas to the
air/f uel mixture reduces the amount
of NOx produced when the f uel is
burned.

The three way catalytic converter
contains precious metals that serve
as catalysts, promoting chemical
reactions to convert the exhaust
gasses without af f ecting the metals.
The catalytic converter is ref erred to
as a three-way catalyst, since it acts
on HC, CO, and NOx. A replacement
unit must be an original Honda part
or its equivalent.
The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place. It can set on f ire any com-
bustible materials that come near it.
Parkyourvehicleawayfromhigh
grass, dry leaves, or other f lamma-
bles.A defective three way catalytic
converter contributes to air pollution,
and can impair your engine’s per-
f ormance. Follow these guidelines to
protect your vehicle’s three way
catalytic converter.
Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way catalytic converter inef f ective. Keep the engine tuned-up.
Have your vehicle diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly.

If you take your vehicle f or a state
emissions test shortly af ter the
battery has been disconnected or
gone dead, it may not pass the test.
This is because of certain ‘‘readiness
codes’’ that must be set in the on-
board diagnostics f or the emissions
systems. These codes are erased
when the battery is disconnected,
and set again only after several days
of driving under a variety of
conditions.
If the testing f acility determines that
the readiness codes are not set, you
will be requested to return at a later
date to complete the test. If you must
get the vehicle retested within the
next two or three days, you can
condition the vehicle f or retesting by
doing the f ollowing.Make sure the gas tank is nearly,
but not completely f ull (around
3/4).
Make sure the vehicle has been
parked with the engine of f f or 8
hours or more.
Make sure the ambient
temperature is between 20° and
95°F.
Without touching the accelerator
pedal, start the engine, and let it
idle f or 20 seconds.
Keep the vehicle in Park. Increase
the engine speed to 2,000 rpm, and
hold it there until the temperature
gauge rises to at least 1/4 of the
scale (about 3 minutes).
Select a nearby lightly traveled
major highway where you can
maintain a speed of 50 to 60 mph
(80to97km/h)foratleast20
minutes. Drive on the highway in
D. Do not use the cruise control.
When traffic allows, drive for 90
seconds without moving the
accelerator pedal. (Vehicle speed
may vary slightly; this is okay.) If
you cannot do this f or a
continuous 90 seconds because of
traf f ic conditions, drive f or at least
30 seconds, then repeat it two
more times (for a total of 90
seconds).
