engine HONDA ACCORD SEDAN 2008 (in English) Owners Manual

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.

ÎThe 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.
In 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 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) in
automatic transmission vehicles or
the engine control module (ECM) in
manual transmission vehicles uses
various sensors to determine how
much air is going into the engine. Itthen 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 for more informa-
tion.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust emissions controls
includethreeorfoursystems:PGM-
FI, ignition timing control, exhaust
gas recirculation (V6 models), and
three way catalytic converter. These
three or four systems work together
to control the engine’s combustion
and minimize the amount of HC, CO,
and NOx that come out the tailpipe.
The exhaust emissions control
systems are separate f rom the
crankcase and evaporative emissions
control systems.
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.
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.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 well maintained.
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
combustible materials that come
near it. Park your vehicle away from
high grass, dry leaves, or other
f lammables. 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.
Have your vehicle diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly.

Make sure the gas tank is nearly,
but not completely, f ull (around
3/4).Without touching the accelerator
pedal, start the engine, and let it
idle f or 20 seconds.
If you take your vehicle f or an
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 vehicle has been
parked with the engine of f f or 6
hours or more.
Make sure the ambient
temperature is between 40° and
95°F. Keep the vehicle in Park
(automatic) or neutral (manual).
Increase the engine speed to 2,000
rpm,andholditthereuntilthe
temperature gauge rises to at least
1/4of thescale(about3minutes).
Without touching the accelerator
pedal, let the engine idle f or 20
seconds.

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 (automatic) or 5th (manual). Do
notusethecruisecontrol.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).If the testing f acility determines the
readiness codes are still not set, see
your dealer.Then drive in city/suburban
traffic for at least 10 minutes.
When traf f ic conditions allow, let
the vehicle coast f or several
seconds without using the
accelerator pedal or the brake
pedal.
Make sure the vehicle has been
parked with the engine of f f or 30
