RE: Low engine coolant light?
My light was always on but once i parked for a while and started back up it went off. I started filling the overflow but noticed the light would still come back on so i checked the overflow. It was empty again and coolant was a few inches from the cap. That went on and on. One day i replaced the water pump which i found was leaking from its weep hole and never had the light come on again. problem solved.
So check your water pump to and not just the sensor.

Exactly! The sensor is located in the overflow tank. The reason it shows on there when the car is cold is because when the car cools down the coolant from the resevoir goes back into the radiator! so check the overflow bottle when it is cold and fill it to the cold mark. When the engine is hot it pushes the coolant into the bottle thats why it reads ok when it is hot!

Your low coolant level sensor is located in the overflow tank and like tmajikman said you're probably running low on coolant in the overflow tank. I would go ahead and remove the overflow tank (two bolts, one in the middle and one in the top and disconnect the line running from the top of the radiator to the bottom of the tank), empty it, and get all of the **** out of the bottom of it by running it in your sink or using your garden hose and clean the tips of that sensor off. Fill it to the proper level and it should work. If that doesn't cure it you need a new sensor.
