Mine has been saying 100-104* all day
I took a look at the sensor, and it looked fine (thought maybe there was water on it).
Unplugged, replugged, now it says 50* and won't move. True temp is around 75*. Is there a way to recalibrate or should I just get a replacement sensor? Not keen on the new sensor idea, car is becoming a nickel and dimer.
EDIT: Something interesting... when it'* unplugged, the display says a flashing 75*, which is about the real temp. Is it reading the temp inside the car? There isn't a way to toggle the display to display the temp inside the car is there?
