my wife drives this car and we tow it behind our motorhome she says the outside temp is wrong is there a way to check
Hmm, so you want to know if the cars outside temp sensor is faulty. Do you have a smart phone, you can download a weather app and check the outside temp and compare it to the one in the car. Plus or minus 5 degree is fine, more than that you might have a bad sensor.
