low coolant light won't go off

My coolant light comes on and sometimes it stays on until I turn off the engine or other times it goes off before turning off the engine. I topped off the reserve tank, but it's still happening. I have a 2002 Chevy Impala LS with a 3.8 L, v6 3800 series engine. Thanks for any help, Nancy

Take a small tool or hard object and tap on the side of the over flow tank where the wire connects. These sensors are bad to read incorrect after some build-up in them occurs.
