Hope everyone is great im having an issue with a sensor my fluid tank Reservoir is full and yet I get the indicator light saying it’s low. If anyone may guide me to the proper steps of fixing this thank you.

Its been 3 years already
i've got the light also, but its very inconsistent
but always comes on every time i drive it!
i'm trying distilled water now to loosen debris
if it doesn't, i'll go through the bottom to change sensor
