Could it be a bleeder valve? I know some systems have them so you can bleed the air out of the highest point in the cooling system.

That would be the case, if your able to you can test it with a multi meter, resistance should be less as temp increases

I doubt if there is anything wrong with the sensor, but it will work better if you hook it up  |

your ecm has pre programed default values, which means when a sensor such as an 02 sensor goes bad your Mil light illuminates and the computer defaults to a pre programed "false" value. That could be why it seems to still work.. Although if it was disconnected your MIL lamp should be on
