It plugs into the bottom of the expansion tank.

Funny that its absence doesn't trigger an alarm. Most sensors fail safe. Thanks!

Lights on, nobody home
So does that one. It should give a "Check Coolant " message if it is working properly.
I soldered mine to a dead short to shut mine up. I think the magnet in the exp tank gave up.
It should be an open circuit until you put a magnet near it. Then it is a closed circuit.

Does the float still work?
