EGR SYSTEM
General Information
EGR system controls the opening vale of EGR valve by transmitting electrical signal (PWM control) from the engine
ECU to vacuum modulator. Also, the engine ECU receives the feedback signals of the amount of air flowing through the
HFM sensor.

EGR VALVE AND TURBO CHARGER ACTUATOR CONTROL VACUUM
CIRCUIT
Vacuum Modulator
The biggest difference between the vacuum circuit and layout of the Hoover EGR system after K2004 has been intro-
duced is the location of the vacuum modulator for EGR valve control and the function of the other modulator. In case of
EGR equipped vehicle (IDI Engine), it performs the role of controlling the PLA of injection pump whereas, in DI engine, it
controls the turbo charger actuator.
