Not easy to do that in the abstract! Look for obvious errors - is there a
CISpeptide near by which has been labelled wrongly in the PDB? Is there a
genuine error - too many residues, lost residues etc? Or is it just that
the density is poor, and it is hard to fit any coordinates and equally hard
to refine them sensibly.

If you are sure there are no obvious errors to correct the is a rEFINE
option to improve the Ramachandran plot - or you can restrain the
ramachandran angles..

But if there is an error the plot is correctly trying to alert you and the
error needs creating....
