engine HONDA ACCORD 2001 CF / 6.G Owners Manual

ÎÎ
In Canada, Honda vehicles comply
with the Canadian Motor Vehicle
Saf ety Standards (CMVSS) f or
Emissions valid at the time they are
manuf actured.
The burning of gasoline in your car’s
engine produces several byproducts.
Some of these are carbon monoxide
(CO), oxides of nitrogen (NOx) and
hydrocarbons (HC). Gasoline
evaporating from the tank also
produces hydrocarbons. Controlling
the production of NOx, CO, and HC
is important to the environment.
Under certain conditions of sunlight
and climate, NOx and HC react to
f orm photochemical ‘‘smog.’’ Carbon
monoxide does not contribute 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
.
Your car has a Positive Crankcase
Ventilation System. This keeps
gasses that build up in the engine’s
crankcase from 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 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 ), dinitrogen
(N ), and water vapor.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO and NOx produced.
The exhaust emissions controls
include three systems: PGM-FI,
Ignition Timing Control and Three
Way Catalytic Converter. These
three 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 from 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 Fuel Control.
The Engine Control Module (ECM)
or 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 operat-
ing conditions.
The emissions control systems are
covered by warranties separate f rom
the rest of your car. Read your
warranty manual f or more inf orma-
tion.
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
Genuine Honda replacement parts or
their equivalent f or repairs. Using
lower quality parts may increase the
emissions f rom your car.

Keep the engine tuned-up.
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.
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.
Park your car away f rom 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 car’s three way catalytic
converter. Have your car 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 re-tested within the
next two or three days, you can
condition the vehicle for re-testing
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
(automatic transmission) or
Neutral (manual transmission).
Increase the engine speed to 2,000
rpm and hold it there until the
temperature gauge rises to at least
1/4of thescale(approximately3
minutes).

This manual complements the Service Manual by
providing in-depth troubleshooting inf ormation f or each
electrical circuit in your vehicle.
This manual describes the procedures involved in the
replacement of damaged body parts.
This manual covers maintenance and recommended
procedures f or repair to engine and chassis components.
It is written f or the Journeyman mechanic, but is simple
enough f or most mechanically-inclined owners to under-
stand.
