The sensor I have is for the replacement that’s on or near the driver side bumper on top of the radiator the smaller in front of the bigger radiator. Which route would be best to get to that?

So you need the location for the HVAC system reference which is called the outside air temperature sensor. here ya go. You might need to get to it from under the car. Thanks for the images they help.
