    check coolant level sensor and its wiring. check connector for corrosion

    before you sugest sensor be bad, separate connector and put car fuse in.... if no CEL any more - replace coolant level sesor. If the problem does not dissapeare - rewire...

    Coolant level sensor is bad. My 99 FLD had the same problem and in the 7yrs I owned it, I replaced it 6 times.... just a bad design.
