The EC2/3 automatically detects a broken / open air temp sensor and just assumes the air is 75 deg F. The B controller always does this because it doesn't use a temp sensor. You may have to adjust the mixture control to compensate but not a big deal. I'm not home now but will be glad to get PN for you when I get back. It is a thermistor with a resistance of 2700 ohms at 75 F. Most any one fitting that description would work.

What is it's job? Do we know the part number if I have to order it online? The engine seems to run ok without it but I of course want to replace it.

Perhaps better suited for Tracy but I gotta make a start.
