2001 HONDA ACCORD COUPE catalytic converter

Parking

Always use the parking brake when you park your car. The indicator onthe instrument panel shows that the
parking brake is not fully released; itdoes not indicate that the parking
brake is firmly set. Make sure the
parking brake is set firmly or your car may roll if it is parked on an
incline.
If your car has an automatic
transmission, set the parking brake before you put the transmission in
Park. This keeps the car from
moving and putting pressure on the
parking mechanism in the
transmission — making it easier to
move the shift lever out of Park
when you want to drive away. If the car is facing uphill, turn the
front wheels away from the curb. If
you have a manual transmission, put it in first gear.
If the car is facing 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 fully
released before driving away. Driving with the parking brake
partially set can overheat or damage
the rear brakes. Parking Tips
Make sure the moonroof and the
windows are closed.
Turn off the lights. Place any packages, valuables, etc.,
in the trunk or take them with you.
Lock the doors with the key or the
remote transmitter.
On EX and EX-V6 models

Check the indicator on the driver's
door to verify that the security
system is set.
Never park over dry leaves, tall
grass, or other flammable materials. The three way catalytic
converter gets very hot, and could
cause these materials to catch on

fire.

Technical Information

Driving in Foreign Countries

If you are planning to take yourHonda outside the U.S. or Canada,
contact the tourist bureaus in the
areas you will be traveling in to find
out about the availability of unleaded
gasoline with the proper octane

rating.

If unleaded gasoline is not available,
be aware that using leaded gasoline in your Honda will affect perfor-mance and fuel mileage, and damage
its emissions controls. It will no
longer comply with U.S. andCanadian emissions regulations, and
will be illegal to operate in North America. To bring your car back into compliance will require the replace-
ment of several components, such as
the oxygen sensors and the three
way catalytic converter. These re- placements are not covered under
warranty.
Technical Information

Emissions Controls

Exhaust Emissions Controls
The exhaust emissions controls include three systems: PGM-FI,Ignition Timing Control and Three
Way Catalytic Converter. These three systems work together tocontrol the engine's combustion and
minimize the amount of HC, CO, and
NOx that comes out the tailpipe. The
exhaust emissions control systemsare separate from the crankcase and
evaporative emissions control
systems.
PGM-FI System

The PGM-FI System uses sequential multiport fuel 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 fuel to inject under all operat-
ing conditions.
Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amountof HC, CO and NOx produced.
Three Way Catalytic Converter
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 2), dinitrogen
(N2), and water vapor. Replacement Parts

The emissions control systems are
designed and certified 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 newGenuine Honda replacement parts or

their equivalent for repairs. Using

lower quality parts may increase the emissions from your car.

The emissions control systems are
covered by warranties separate from

the rest of your car. Read your

warranty manual for more informa-
tion.
Technical Information

Three Way Catalytic Converter

The three way catalytic converter contains precious metals that serveas catalysts, promoting chemical
reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converter is referred 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 fire any com-
bustible materials that come near it. Park your car away from high grass,dry leaves, or other flammables. A defective three way catalytic
converter contributes to air pollution,
and can impair your engine's per-
formance. Follow these guidelines to
protect your car's three way catalyticconverter.
Always use unleaded gasoline.Even a small amount of leaded
gasoline can contaminate the catalyst metals, making the three
way catalytic converter ineffective. Keep the engine tuned-up.
Have your car diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not running properly.
