As always, check grounds.  I would think that if the
sensor went bad giving a false reading of no coolant,
the needle would jump up as well.  Just a blinking LED
would make me suspect a circuit independent of the
sensor...  Especially if it has been intermittant.

But definitely check the coolant level, anyway.
