For some reason the sensor is picking up moisture in the gas tank. This could happen since this time of year you have the cooler temperatures at night and warmer threw the day. Try a red bottle of Heat, or a product that has Isopropyl in it. This dissipates the moister that collects inside of the gas tank. Where as a methanol product does not. (yellow bottle of heat)

would this be a one time thing or on every fillup?


Not too sure on that one but adding Isopropyl will not hurt anything. You may want to do some research on this, see if there is anything out there on this sensor.
