Cue the broken wire answer. Just because the connector is attached, doesn't mean current is getting
to the proper wire. Unplug the connector at the expansion tank, get a short piece of wire, bend it into a "U" shpae and connect it to both terminals on the connector. Start the car and if this cures the warning, you have a defective sensor or the wires aren't making contact. This ain't rocket science - the answer should be pretty simple, hopefully (unless you have a break in the wiring harness somewhere).
