INSPECTION
Check for damage, cracking or deterioration. Replace if faulty.
Caution
1. Stop the engine immediately if engine misfiring
occurs, otherwise an abnormally hot exhaust system
will damage the catalytic converter or other underb ody
parts.
2.
Correct and repair the ignition or fuel system if t here
are malfunctions, otherwise engine misfiring may
occur which will damage the catalytic converter.
3. Observe manufacturer’s specifications when doing
service work.

CATALYTIC CONVERTER17399939993
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

CLUTCH PEDAL CHECK AND ADJUSTMENT
1. Turn up the carpet, etc. under the clutch pedal.
2.Measure the clutch pedal height as shown in the fig ure.
Clutch pedal height
Standard value (A):
mm
3.If the pedal height is not within the standard valu e, loosen
the lock nut and adjust the pedal height to the sta ndard
value using the adjusting bolt (vehicles without au to-cruise
control), or using the clutch pedal position switch or push
rod (vehicles with auto-cruise control).

8.
Measure the clutch pedal play.
Clutch pedal play (play at the
pin)
Standard value (B):
mm in.)
If the clutch pedal play is outside the
adjust with the push rod.
Caution
Do not push in the master cylinder at this
time.
After completing the adjustments, confirm that the clutch
pedal free play (measured at the face of the pedal pad)
and the distance between. the
pedal (the face of
the pedal pad) and the
when the clutch is disen-
gaged are within the standard value ranges...
Clutch pedal free play (including the
pin play)
Standard value (C): 6-13 mm
in.)
Distance between the clutch pedal and
when the clutch is disengaged
Standard value (D):
mm (2.76 in.) or more
If the clutch pedal free play and the distance betw een
the clutch pedal and the when the clutch is disen-
gaged do not agree with the standard values, it is probably
the result of either air in the hydraulic system or a faulty
master cylinder or clutch. Bleed the air, or disass emble
and inspect the master cylinder or clutch.
Turn back the carpet, etc.
