I know they are stupid, but if it is there, I wish it was accurate
There is a very useless Nissan dealership in my town that cannot tell me if calibration is possible, or if replacement of the thermistor is the fix...
It is 4 degrees high.................ANYBODY?.............

take the sensor off, clean it, spray some wd40 put it back on, its mounted near the lower driver's side corner of the radiator, dont know if it will help, got mine so caked up with mud it pulled it off, i just did the above and it works fine again
