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.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 well maintained.
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
combustible materials that come
near it. Park your vehicle away from
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 vehicle’s three way
catalytic converter.
Have your vehicle 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).Without touching the accelerator
pedal, start the engine, and let it
idle f or 20 seconds.
If you take your vehicle f or an
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 retested within the
next two or three days, you can
condition the vehicle f or retesting by
doing the f ollowing.
Make sure the vehicle has been
parked with the engine of f f or 6
hours or more.
Make sure the ambient
temperature is between 40° and
95°F (4° and 35°C). Keep the vehicle in Park
(automatic) or neutral (manual).
Increase the engine speed to 2,000
rpm,andholditthereuntilthe
temperature gauge rises to at least
1/4of thescale(about3minutes).
Without touching the accelerator
pedal, let the engine idle f or 20
seconds.
