GENERAL INFORMATION
The three-way catalytic converter, together with
the closed loop air-fuel ratio control (based on the
oxygen sensor signal) oxidizes carbon monoxides
(CO) and hydrocarbons (HC), and reduces nitrogen
oxides
REMOVAL AND INSTALLATION
When the mixture is controlled at stoichiometric
air-fuel ratio, the three-way catalytic converter p ro-
vides the highest purification against CO, HC, and
and Post-installation Operation

INSPECTION
Check for damage, cracking or deterioration. Replac e if faulty.
Caution
1. Stop the engine immediately if engine misfiring oc-
curs, otherwise an abnormally hot exhaust system
will damage the catalytic converter or other under- body parts.
2.Correct and repair the ignition or fuel system if t here
are malfunctions, otherwise engine misfiring may oc -
cur which will damage the catalytic converter.
3. Observe manufacturer’s specifications when doing
service work.
