display says that out there are 120 °F.

what to do?

 

check to make sure that your temp sensor didn't fall off from the front bumper clip and is not against the radiator.

 

where is the sensor?
have you a picture?

 

You have to get under the car and take of the body pan in the front about 15 or 20 8mm screws..Mine is on the drivers side behind the bumper..It looks like a point..almost like an electricians tool to check an outlet to see if it has power, but just the tip about two inches big..mine is hanging but thats how it has always been..but just recently it started go to 136 degrees..I think the fan might be blowing on it because when I drive it goes back to the normal temp..if any one has experience let me know..I have the lorinser bumper so maybe thats why its hanging (no clip) does anyone have a solution..thanks

 

The Temp-sensor is just clipped into the driver sider opening in the bumper, where also the horn is behind. It is the egg-shaped plastic cover, which pops out. On the reverse side of the cover there is a socket which holds the sensor. It may have fallen out or the plug got disconnected. No panels to be removed so far.
