LP(low-pressure) EGR system is composed of LP EGR valve, Exhaust Pressure Control Valve, LP EGR differential pressure sensor to recirculate gas from DPF's rear side to the compressor's front side.

LP EGR valve is controlled by vaccum and is coposed of solenoid valve controlling the amount of vaccum (is opened by vaccum). Feedback position senor is mounted separately

Exhaust Pressure Control Valve is controlled by DC motore directly in order to modulate the LP EGR control pressure and mounted with Integrated position sensoron DPF' rear side.

LP Differential pressure sensor measures the pessure of the DPF's rear side between compression's front to determine and provide the information to the ECU to determe the amount of EGR
