probably the float sensor is clogged, stuck, or malfunctioned. this will require access to the reservoir inside the bumper cover.
you may be able to access the sensor by removing the fender liner from the wheel well.

before you go about removing things, give a firm tap to the bumper with your hand and see if the float unclogs.

Perhaps the float is soggy...
