Mine went to heaven about 2 years ago, and seeing that to replace the sensor requires removing a lot of front end parts, so I decided to pass, unless someone knows a way of cutting into some cosmetic parts to get to the sensor, which I don't know exactly where it is located. The funny is that when the sky decided to drop heavy rain, the sensor sends a default reading to the gauge of -40 deg F.. This has happened a couple of times now.

 

The only thing I know is that my manual says "The temperature sensor is in the front bumper." Nice and specific.

 

Take off the front bumper its 6 clips and 6 screws

Sensor is in front of the condensor

 

It is right behind the front bumper and removing that front bumper is very easy.

 

On a warm day, you can safely access the temp sensor by removing the lower grill.
