•  Based on the signals from the PCM, the spool valve inside the OCV moves up and down. With the up/down movement of the spool valve, the amount of oil supplied to the metering oil pump is controlled, and the oil pressure inside the metering oil pump is kept constant.

•  For OCV control, refer to CONTROL SYSTEM, OIL PRESSURE CONTROL. (See OIL PRESSURE CONTROL OUTLINE [13B-MSP].)
