those "multi function senders" are about $40 or so in the aftermarket.

removal via big wrench, it unscrews from the hose flange.

before I replaced mine I dug out the expansion tank low level connector
and verified that it was not causing the problem (they set off the same
light).

the design seems like it was intended to cause this sender to fail...
