NOTE
When disconnecting the vacuum hose, make an identification
mark on it so that it can be reconnected to the original posi-
tion.
(1) Disconnect the vacuum hoses (non stripe and red stripe
hoses) from the solenoid valve
(2) Disconnect the harness connector from solenoid valve.
(3) Connect a hand vacuum pump to the nipple to which the red-striped vacuum hose was connected.
(4) Apply a vacuum and check for air-tightness when voltage applied directly to the evaporative emission purge solenoid
when the voltage is discontinued.

EGR SYSTEM INSPECTION
(1) Disconnect the vacuum hose (green striped hose) from the exhaust gas recirculation
(EGR) valve, and then connect a
manual vacuum pump via the three-way terminal.
(2) Check the following points when the engine is cold [enginecoolant temperature is
20°C (68°F) or below] and when the
engine is warm [engine coolant temperature is
70°C (158°F)
or higher].

(3) Disconnect the three-way terminal and connect the manual
vacuum pump directly to the exhaust gas recirculation
(EGR) valve.
(4) Check whether the engine stalls or the idling is unstable
when a vacuum of 155 mmHg (5.9 in.Hg) or higher is
applied during idling.

(2) Start the engine and check to see that, after raising the
engine speed by racing the engine, vacuum raises prop-
ortionately with the rise in engine speed.
NOTE
if there is a problem with the change in vacuum, it is
possible that the throttle body port may be clogged and
require cleaning.
EGR VALVE
INSPECTION MI’IICKF
(1) Remove the EGR valve and check it for sticking, deposit of
carbon, etc.
If such condition exists, clean with adequate solvent to en-
sure tight valve seat contact.
(2) Connect a hand vacuum pump to the EGR valve.
(3) Apply a vacuum of 500 mmHg (19.6 in.Hg.) and check air
tightness.
(4)Blow in air from one passage of the EGR to check condition
as follows.
INSTALLATION
(1) Install a new gasket and EGR valve, tighten bolts to
specified torque.
Specified tightening torque: 17-26 Nm (12-19 ft.lbs.1
THERMAL VACUUM VALVE Y~JICNG
INSPECTION
(1)Disconnect the vacuum hoses from the thermal vacuum
valve, and connect a hand vacuum pump to nipple of the
thermal vacuum valve.
(2) Apply a vacuum and check the air passage through the
thermal vacuum valve.

(4) Apply a vacuum and check for air-tightness when voltage
applied directly to the EGR solenoid when the voltage is
discontinued.
(5) Measure the resistance between the terminals of the sole-
noid valve.

CATALYTIC CONVERTERMl7lcBc
INSPECTION
Check for damage, cracks or fusion and replace if faulty.
Caution
1. Operation of any type, including idling, should be
avoided if engine misfiring occurs. Under this condi-
tion the exhaust system will operate at abnormally high temperature, which may cause damage to the
catalyst or under-body parts of the vehicle.
2. Alteration or deterioration of ignition or fuel system, or any type of operating condition which results in
engine misfiring must be corrected to avoid overheat-
ing the catalytic converters.
3. Proper maintenance and tuneup according to manu-
facturer’s specifications should be made to correct theconditions as soon as possible.
