Hyundai Genesis (DH): Lubrication System / Oil Pump Description and Operation
2-Stage variable Vane Pump improves the fuel economy by
controlling the oil pressure into two stages and by optimizing the
hydraulics of low/medium rpm.
The oil pressure/temperature sensor delivers the pressure
information to ECM by measuring the oil pressure and temperature from
oil pump, and ECM maintains the pressure discharged from the RPM
constantly by controlling the proportional control valve.


Control the frequent operation of solenoid by setting the
mode change timing differently when increasing or decreasing the engine
rpm.
