Incorrect outside air temperature and heat not working

[Bhansen]

I have a 2023 Mach E premium and the parking sensors have failed. Not a big deal right now, but then it began to show an incorrect outside air temperature and now the cabin heater is not working. It is currently in the 40's here in the Portland area, but the car thinks it's 74 degrees outside and is blowing cool air even when the temperature is set to 85. We are going to unplug the 12v battery to see if a reset fixes it, but I'm not feeling positive. Anyone else have this issue and can fix it without taking it to the dealership?

Yes, I have the heat on and it's parked outside. Today I started driving it and it instantly went from reading 60 to 74 degrees outside and still blowing cool air.

feels like you're going to need a trip to the dealership...
