2005 HONDA ODYSSEY catalytic converter

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. This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise to
about the middle of the gauge. In
severe driving conditions, the pointer
may rise to the upper zone. If it
reaches the red (hot) mark, pull
safely to the side of the road. For
instructions and precautions on
checking the engine’s cooling
system, see page .369

Avoid driving with an extremely low
f uel level. Running out of f uel could
cause the engine to misf ire, damaging
the catalytic converter.

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.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from 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 the vehicle is f acing downhill,
turn the front wheels toward the
curb.
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.
Make sure the moonroof 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 and the tailgate. Place any packages, valuables, etc.
in the cargo area, or take them
with you. Turn of f the lights.

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)
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.This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
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 ), nitrogen
(N ), and water vapor.
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 f or more informa-
tion.

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.
Parkyourvehicleawayfromhigh
grass, dry leaves, or other f lamma-
bles.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.
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.
