Hello.
I bought a Jeep WJ and the EVIC console only displays -40 on the ambient temperature no matter what the weather is, i already located the sensor on the grille and disconnected and plug it back in but it stills the same, could not found anything on the internet regarding this issue, do you think could be the sensor?

I believe that the scanner should report if a sensor is malfunctioning but would not tell, as this is not engine related...
