Anyone seen this yet? I have a 2022 2.7L Badlands built in May/June, 2022 with 8,400 miles.

Dealer can't get it in for service for another week. Yellow Check Engine light is persistent, never turns off. Anything to be concerned about? Safe to drive short distances in the meantime?

I had the same issue back in February 2023. The car was 1 year old. The tech at the dealership found that the sensor (located in the mirror assembly on the driver's side) was cracked and rusted, that the wiring was corroded, and also noticed that the mirror assembly was cracked. They had to change the whole mirror assembly.
Yesterday, I got the same error message (following a day of wrong temperature reading), almost one year later! I still need to take the car in. But this time, the mirror assembly appears intact.
I suspect this issue may be more widespread than what the number of posts on the subject suggests.

Different issue in my case. In the engine bay, the air temperature sensor on the air box had a wire that was broken, presumably chewed by a rodent? Repairing the broken wire fixed the issue.

That actually makes me feel better. It could be a different issue, as you have mentioned. I was driving back home yesterday evening and had to use the heater, which would not do much heating. My understanding is that the actual heating is based on the measured temperature difference (outside vs inside vs setting), unlike previous cars I owned where you could heat the interior even on a scorching hot day (given your location, I suspect you don't get to experiment with the heater too much!!).
On the other hand, the displayed outside temperature is 70 degrees (Celsius that is) too high, just like the first time it happened.
One thing is for sure, there is no shortage of sensors on those cars!

As it turns out, I cancelled the appointment with the dealership. After about a week, the reading went back to normal and the engine light turned off. During that week, the humidity level was quite high, which is typical during the change of season. I suspect the sensor doesn't like it. That could also explain the corroding a year before at around the same period.

Do you happen to know what the code was? Was it P0113 - Intake Air Temperature Sensor 1 Circuit High Bank 1? I just had something chew through mine today and the Bronco won’t start now and has a flashing Check Engine Light. I soldered new wires in and it didn’t fix the problem, did the dealer have to do anything else?

I just replaced the airbox temp sensor myself and cleared the error with Forscan. No further issues have come up. I do not know what the code was, sorry. However, I never had an issue starting the Bronco. Mine ran as normal, even with the broken wire to the temp sensor. If yours is not starting, something else is up.

I know this thread is older, but I just had this issue with my 2023 BL. What sucks is that I had the check engine light in the am and I worked all day with no available dealer open to check it out. As I was leaving work at 4pm, the sensor was reading 132 degrees and my cooling fan was running when it was only 31 degrees outside. Found the sensor location (thanking this thread) and tried to Clean / wipe it off and it went down to 44 degrees when it was actually 31. As I was driving home, I watched it climb back up to 100 degrees multiple times and kept having to wipe it down until I got home where it read 32 degrees. This morning it was only a degree or two off. My question is: Is this covered under warranty, if not what can I expect for a cost, and is it an easy fix if I do this myself? How long can I drive with this issue before it becomes a major problem? I do not want to burn out the cooling fan if it keeps running for no reason.
