It is in circuit as follows:
From the circuit I would have expected it to be a pulldown resistor style to indicate that the connector is plugged in. The other pins of the connector are a wind sensor pulse output.
Any help is greatly apreciated, Thanks
Update : After the helpful insight about checking it to be a PTC of NTC thermister I performed measurements and it was 22kOhms. Held it with my fingers and it decreased to 20k and breathing on it I managed to get it to go down to 18k.
In circuit measurements with the Vcc = 5V, across the thermistor it was 1.4 V approx.
So It is an NTC resistor
And it makes sense that it be an NTC resistor because when the weather is too cold, the wind sensor could freeze up and you would not know if the measurement is valid. The resistance would go up and therefore the voltage and that would be tending to a similar scenario as if the sensor was disconnected. i.e. Open circuit.
