During 6 Cylinder Mode
With rocker arm oil control solenoids A (Bank 1), B (Bank 1), and A (Bank 2) OFF, the rocker arm oil control valves direct oil pressure. Oil pressure enters the primary rocker arm from the oil passage in the rocker shaft, and it moves the VTEC switching piston, sliding it into the secondary rocker arm, and locking the primary and secondary rocker arms together. The rocker arms are lifted by the camshaft, and all cylinders are active.
