first let me ask you to clarify. do you mean it reads low temp or that it reads lower then what the banks and the temp outside is???? I have the same problem on my 1998 Regal. The temperature gauge reads ~ 20 degrees lower than actual. Occasionally it will read correct, but not for long. I can't find any information as to where the sensor is, or the supporting cabling that will help me trobleshoot the problem. JJD Not compared to Banks, but actual temperature readings outside. For example, if it is 95 degrees outside, the regal says ~72 degrees. It used to read withing about 1 degree to the actual outside temp, but now it is at least 20 degrees lower. I have a 99 Buick Park Avenue Ultra, and my temperature gage was doing the same thing the dealer replaced the sensor, located on the left front of the radiator. They charged me $80.00, if I had known where and what to look for I could have done it for a lot less.
If the outside temperature gauge is not reading the right temperature on a Buick Regal, perhaps it has become damaged. It can also not read the right temperature if it is wet or covered with dirt or snow.
Most likely a bad sensor

The thermostat is probably set for 190 degrees and that is the point it opens at.

I need to know how to change the temperature gauge from Celsius to Fahrenheit on a 2012 Buick LaCrosse
The sending unit is likely faulty
what is the pressure in the gauge with outside 90 degree temperature with freon 22
The outside temperature gauge on a vehicle is extremely accurate. It generally has a deviation of about 1 degree plus or minus.
you either have a diying battery or a ground short
outside temp. that is what it means it is not a trick .
The outside temperature gauge says ICE this morning (AM) because it may be icy outside. Also, the temperature outside may be below 32 degrees, which is freezing temperatures.
