Three Way Catalytic Converter

The three way catalytic converter contains precious metals that serve
as 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 actson 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 vehicle away from high
grass, dry leaves, or other flamma-

bles.
(U.S.: EX, Canada: Si)

A defective three way catalytic converter contributes to air pollution,
and can impair your engine's per-
formance. 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 ineffective.
(U.S.: DX, HX, Canada: DX)

Keep the engine tuned-up.
Have your vehicle diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not running properly.
