The readings of the sensors can be read with a subaru select monitor, or a laptop. You can compare them with an ordinary thermometer. The sensor might not match the thermometer exactly, but if you took several readings at different temperatures you should be able to see whether they follow the same trend. If you still have the old serial cable I sent you, I'll talk you through how to do it.
