CATALYTIC CONVERTER
GENERAL DESCRIPTION (CATALYTIC CONVERTER)M1173005300131
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), also reduces nitrogen oxides
(NOx). When the mixture is controlled at stoichiometric
air-fuel ratio, the three way catalytic converter pro-
vides the highest purification against the three con-
stituents, namely, CO, HC and NOx.

REMOVAL AND INSTALLATIONM1261001700386
For vehicles with ABS, do not strike the ABS rotors installed to the BJ outer race of drive shaft
against other parts when removing or installing the drive shaft. Otherwise the ABS rotors will be
damaged.
For vehicles with ABS, be careful not to strike the pole piece at the tip of the front wheel speed
sensor with tools during servicing work.
