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.

CAUTION
•Do not strike the ABS rotors installed to the BJ outer race of drive shaft against other parts when
removing or installing the drive shaft. Otherwise the ABS rotors will be damaged.
•Be careful not to strike the pole piece at the tip of the front ABS sensor with tools during servicing
work.
Post-installation Operation
•Check the dust cover for cracks or damage by pushing it
with your finger.
