Pull the wire harness off the level sensor. It's located at the bottom of the overflow tank. Clean the electrical contacts, and push it back in. The check message should now disappear.
Very rarely does the sensor itself go bad. 9 times out of 10 it's just the electrical contacts. In some cases, the sensor float in the tank gets gunked up, and needs cleaning. But you have to take the tank apart just to clean it, so if you've gone that far you may as well replace the sensor.
