Help needed with custom variable resistor value/range? Answered

i would like 0.4ohm to4ohm variable resistor to replace car IAT sensor, i looked online for pot and resistor combination couldn`t figure it out then i went up a level and was searching variable wemos resistor (it would be nice to see on a small display the original sensor value and the fake one that wemos outputs, just an idea) but no luck either, is there anyone who can point me in the right direction either analog or digital way?
thnx alot
