Could be corroded sensor under front bumper, shorted wire or other issue.

Could also be a faulty printed circuit board that has some weak solder joints. I've had that happen on mine long ago. It was storing a code for the pre-tensioner but that component tested good. I replaced the sensing and diagnostic module and the light never came back.
It may be best to scan for trouble codes and follow the appropriate diagnostic flow chart and see where it leads.
