Apologies for jumping in, I'm sure David will have
some better practical advice and information to add.

The Ford sensor is a thermistor RTD.
It's quite robust, and simple to interface.
There is a published Resistance vs Temp graph, and you
can easily calibrate an individual unit to greater
accuracy.

AFAIK, the same basic unit is used for both air and
coolant, the wet one has the RTD sealed for
protection.
