General System Operation
GENERAL DESCRIPTION This EGR system consists of the EGR duty solenoid, vacuum tank, vacuum regulator, and VSV for cutting
EGR, and is controlled by Engine Control Module (ECM) through EGR duty solenoid.
The optimum
EGR volume is determined by ECM based on three main signals (Engine RPM, intake air volume, ECT) to achieve more precise EGR control.
