catalytic converter HONDA CIVIC COUPE 2005 7.G Owners Manual

The odometer shows the total
distance your vehicle has been
driven. It measures miles in U.S.
models and kilometers in Canadian
models. It is illegal under U.S.
federal law and Canadian provincial
regulations to disconnect, reset, or
alter the odometer with the intent to
change the number of miles or
kilometers indicated.The odometer and the trip meters
use the same display. Switch
between these displays by pressing
the Select/Reset knob repeatedly.
When you turn the ignition switch to
ON (II), the meter you last selected
is displayed.
The trip meter shows the number of
miles (U.S.) or kilometers (Canada)
driven since you last reset it.There are two trip meters: Trip A
and Trip B. Each trip meter works
independently, so you can keep track
of two dif f erent distances.
To reset a trip meter, display it and
then press and hold the Select/Reset
knob until the number resets to ‘‘0.0’’.
Both trip meters will reset if the
vehicle’s battery goes dead or is
disconnected.
This shows how much f uel you have.
It may show slightly more or less
than the actual amount. The needle
returns to the bottom after you turn
of f the ignition.

If your vehicle has an automatic
transmission, set the parking brake
bef ore you put the transmission in
Park. This keeps the vehicle f rom
moving and putting pressure on the
parking mechanism in the
transmission.If the vehicle is f acing uphill, turn
the f ront wheels away f rom the
curb. If you have a manual
transmission, put it in f irst gear.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb. If you have a manual
transmission, put it in reverse gear.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly or
your vehicle may roll if it is parked
on an incline.
Make sure the moonroof (if
equipped) and the windows are
closed.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
Lock the doors.
Place any packages, valuables, etc.,
in the trunk or take them with you.
Turn of f the lights.

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 f rom
the rest of your vehicle. Read your
warranty manual f or more inf orma-
tion.
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) 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. It then controls how much f uel to inject
under all operating conditions.
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.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.

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 temperaturefor the chemical reactions to take
place. It can set on f ire any com-
bustible materials that come near it.
Park your vehicle away f rom high
grass, dry leaves, or other f lamma-
bles.
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.
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.
