Outside Temperature

[nate704]

The main outside temperature displayed on the center top screen is always 5-12F higher then the actual temperature when comparing with phones, actual thermometer, internet sites, etc.
Is it normal or something that needs to be reported for service?

That's a big delta. I would get it checked.

Ours is pretty consistent with my phone, maybe 1-2 degrees off at most. I just wish it calibrated quicker as it takes a few minutes to acclimate to outside air after I leave the garage. The Model S and previous cars didn't take nearly as long to update outside temp.

Does anyone know where the ambient sensor is located? I am seeing two different locations from the service manual and Parts manual.

Car temperature sensors are pretty close to the road. That helps them detect potential icing situations. However, on sunny days heat will radiate from the pavement, showing as a few degrees higher than the ambient AIR temperature is as reported by weather apps.

EDIT: This will appear worse if stopped / stuck in traffic, and will be closer to normal air temp at highway speeds I would think.

I assume it’s persistent, not just when you first get in the car? Mine takes several minute to equilibrate but is pretty accurate once it does

The outside air temp sensor wiring can be damaged by rodents. If the temperature readings are erratic or inaccurate then have Tesla Service check the sensor and the wiring harness for signs of being chewed.

Keep in mind internet reported temperatures are not for your exact location. It is for the location of your local weather reporting station. It can be 5-10 degrees different at our house.

 

[Why?]

Temp reads my garage temp properly. After about 15-30 minutes of driving, the displayed temp drops precipitously to the accurate ambient temp. I’m taking it in in a week about that and a couple other minor issues.
