P0663 Intake Manifold Tuning Valve Control Circuit/Open (Bank 2) Low
The P0663 code means the bank 2 variable intake valve control circuit is open, so the valve does not get current when it is commanded. It can cause a slight loss of power at certain engine speeds. Check the fuse, connector and wiring first.
