Valve pause mode

Rocker arm oil control solenoids A and B are both on. Engine oil pressure from the oil pump passes the spool valve and the rocker arm. Engine oil pressure is applied to the intake side pistons and the exhaust side pistons. This causes the primary and secondary rocker arms to separate, shift the valves to their pause positions.
