EGR VALVE CHECK
1. Remove the EGR valve and inspect for sticking, carbon
deposits, etc. If found, clean with a suitable solvent so
that the valve seats correctly.
2. Connect a hand vacuum pump to the EGR valve.
3. Apply 67 kPa of vacuum, and check that the vacuum
is maintained.
4. Apply a vacuum and check the passage of air by blowing
through one side of the EGR passage.
VacuumPassage of air
5.3 kPa or lessAir is not blown out
27 kPa or moreAir is blown out
5. Replace the gasket, and tighten to the specified torque.
Tightening torque: 20±2 N·m
EGR PORT VACUUM CHECK
1. Disconnect the vacuum hose (White stripe) from the
throttle body EGR vacuum nipple and connect a hand
vacuum pump to the nipple.
2. Start the engine and check vacuum remains fairly constant
after racing the engine.
NOTE
If the vacuum fluctuates, the throttle body EGR port may
be clogged and need cleaning.

EGR CONTROL SOLENOID VALVE CHECK
NOTE
When disconnecting the vacuum hose, always make a mark
so that it can be reconnected at original position.
1. Disconnect the vacuum hose (yellow stripe, green stripe,
white stripe) from the solenoid valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to the nipple to which
the green-striped vacuum hose was connected.
4. Check airtightness by applying a vacuum with voltage
applied directly from the battery to the EGR control
solenoid valve and without applying voltage.

CATALYTIC CONVERTER
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 (NOx).When the mixture is controlled at stoichiometric
air-fuel ratio, the three-way catalytic converter
provides the highest purification against the three
constituents, namely, CO, HC and NOx.
