During 6 Cylinder Mode
WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.
With rocker arm oil control solenoid A (Bank 1), B (Bank 1), and A (Bank 2) OFF, the rocker arm oil control valves direct oil pressure. Oil pressure enters the secondary rocker arm from the oil passage in the rocker shaft, and it moves the VTEC switching piston, sliding it into the primary rocker arm and locking primary rocker arms and secondary rocker arms together. The rocker arms are lifted by the camshaft, and all cylinders are active.
