I have a 2004 Grand Caravan which has its check engine light on. I checked the code and it came up with P0072 which is the Ambient Air Temperature Sensor Voltage Too Low. Possibly related is the fact that the external air temperature readout on the center overhead console is totally screwed up. First it reads 180F than 30F, than 120F. Thanks for your help.
