It's built into the reservoir. What's wrong with yours?

Simply hit the reservoir, hard, a few times with a rubber mallet or the side of your fist. Do this with the car running. Go check the light, it will be out.

He is correct. I had the same problem this past summer, and it worked. I laughed my ass off in my driveway when it worked.  Laughing

Okay....... These are not Fords, so I'm wondering if there is a logical explanation for this fix.... I'm having this problem, but I do not own a rubber mallet (I don't own Fords, so don't need one!) and would prefer to fix this correctly..... In my case I recently replaced the metal-tank rad with a new plastic-tank rad, so I'm thinking the problem is a lack of grounding(?)... Maybe the mallet trick creates a ground where teflon tape was used (?).....

The sensor is grounded through the black wire on the plug, so the radiator does not make any difference. The sensor are known to stick, and by jarring them, the parts move again. Since you can not find a new one, it is the only fix possible.

I tried and tried to unplug the wire going to my sensor and failed! After monkeying around with it like this, I started the car again and the warning light and chime don't come on now. Go figure. Thanks guys!

The sensor started acting up again. I cleaned it up, removed and reconnected the wire, and banged it around a bit, as had been suggested as a fix. It is now functioning properly. Banging it more apparently fixed it.
