2021 Ram 1500 Long Horn Ambient Air Temperature Sensor Replacement

[Namwal]

My ambient air temperature sensor was registering off the chart and then I had a check engine light come on. I took it to the dealer and they were going to charge me $1400 to replace the drivers side mirror where the sensor is located! My own research shows the removable panel on the mirror that gives you access to the sensor. I ordered a new sensor from MoPar for $14.00. Has anyone ever replaced their sensor or can you guide me to instructions for replacement on the 2021 Ram 1500?

So this is the outside air temp sensor?

Namwal.....Did this fix your problem? Just yesterday, my outside temperature was showing 111 degrees when I left work. It was actually 80 degrees outside. By the time I drove home (45 minutes), it was saying that it was 158 degrees outside! This morning, it was telling me that hit was 165 degrees outside! I'm thinking I may have to order one of these sensors and replace mine.

And now this morning....I an error message showing "Stop/Start Unavailable. Service Stop/Start System". What's this about?????

I broke the intake air sensor at the air box on my 2021 and got the expected P0113 code but I also got the Service Stop Start System symbol on my dash too. I'll know if they're related when I fix the sensor and will post back.

Yup, they were related. Fixed the sensor and the Service Stop Start System light turned off.
