EXHAUST GAS RECIRCULATION
(EGR) SYSTEM
GENERAL INFORMATION (EGR SYSTEM)M1173005200327
The exhaust gas recirculation (EGR) system lowers
the nitrogen oxide (NOx) emission level.
When the air/fuel mixture combustion temperature is
high, a large quantity of nitrogen oxides (NOx) is
generated in the combustion chamber.
Therefore, this system recirculates part of emission
gas from the exhaust port of the cylinder head to the
combustion chamber through the intake manifold to
decrease the air/fuel mixture combustion
temperature, resulting in reduction of NOx.The EGR flow rate is controlled by the EGR valve so
as not to decrease the driveability.
OPERATION
The EGR valve is being closed and does not
recirculate exhaust gases under one of the following
conditions.
Otherwise, the EGR valve is opened and recirculates
exhaust gases.
•The engine coolant temperature is low.
•The engine is at idle.
•The throttle valve is widely opened.

EGR PORT VACUUM CHECK <4G1>M1173002900167
1. Disconnect the vacuum hose (Green stripe) from
the throttle body EGR vacuum nipple and connect
a hand vacuum pump to the nipple.
2. Plug the vacuum hose (Green stripe).
3. Start the engine and check that, after raising the
engine speed by racing the engine, purge vacuum
raises according to engine speed.
NOTE: If there is a problem with change in
vacuum, the throttle body purge port may be
clogged and require cleaning.
EGR PORT VACUUM CHECK <4G6>M1173002900156
1. Disconnect the vacuum hose (White stripe) from
the throttle body EGR vacuum nipple and connect
a hand vacuum pump to the nipple.
2. Plug the vacuum hose (White stripe).
3. Start the engine.
4. Check that a fairly constant negative is generated
regardless of the engine speed.
5. If no negative pressure is generated, the port is
probably blocked and should be cleaned.

CHECK <4G1>
M1173003100238
NOTE: When disconnecting the vacuum hose,
always make a mark so that it can be reconnected at
original position.
1. Disconnect the vacuum hose from the solenoid
valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the
solenoid valve (refer to the illustration at left).
4. Check air tightness by applying a vacuum with
voltage applied directly from the battery to the
EGR control solenoid valve and without applying
voltage.
