4. Check airtightness by applying a vacuum with
voltage applied directly from the battery to the
purge control solenoid valve and without applying
voltage.
5. Measure the resistance between the terminals of
the solenoid valve.
Standard value: 30 − 34 Ω (at 20°C)

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.
