The oil pump control solenoid is located at the front of the oil pump, and connected to the Powertrain Control module (PCM) via hardwired connection. The oil pump control solenoid receives a 12 V power supply from the Engine Junction Box (EJB). The PCM controls the operation of the solenoid valve by controlling the ground path for the solenoid. When the PCM energizes the control solenoid at low engine speed and low engine loads, the oil pump switches to the low pressure mode. This method provides to reduce pumping losses within the oil pump, and optimize fuel economy.
