Bad coolant sensor?

My low coolant light stays on even though the resivoir is full. Is there a way to test the sensor? The plug has three prongs so i'm not sure which one to jump.
 
Start by removing the sensor/probe from the overflow tank.

Inspect it for integrity and if it looks ok to keep using, clean the two tips at the end of the probe.

Scrape/clean/polish down to bare metal and reinstall.

If this doesn't help, consider replacing the sensor entirely.

Works great now! Took my dremel with wire wheel and cleaned the contacts. Thanks!
