DTC P1220-00: Oil Pump Solenoid Control Circuit: General Description

WARNING: This page is about a different variant/trim than selected.

Variable Oil Pump (VOP) is a system to improve fuel efficiency by optimizing engine oil pressure in two modes (low/high) according to engine RPM.

Oil pressure regulating valve turns ON in low pressure mode. Discharge rate of engine oil is decreased as bypassed oil lifting up rotor. It decreases oil pressure.

Fuel efficiency is improved as engine load by rotating the oil pump pulley is reduced.

Mode change depends on engine RPM, oil temperature, and engine load.
