ÎThe 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
.
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 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.
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 . 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 emissions control systems are
covered by warranties separate from
the rest of your car. Read your
warranty manual f or more informa-
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
lowerqualitypartsmayincreasethe
emissions f rom your car.
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.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust emissions controls
include f our systems: PGM-FI,
Ignition Timing Control, Exhaust
Gas Recirculation and Three Way
Catalytic Converter. These four
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 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 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.

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. Keep the engine tuned-up.
Have your car 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).
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.
If you take your car for 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.
Make sure the car has been
parked with the engine of f f or 8
hours or more.Keep the car 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 1/4 of the scale
(approximately 3 minutes).
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 car re-tested within the next
two or three days, you can condition
the car for re-testing by doing the
f ollowing.
