Temp gauge not working

i'm interested as well. mine kinda gets screwy at night time. the temp gauge drops to cold levels when my car is definetly all warmed up... weird...
 
Mine went bad as well. It will most likely have to be replaced. The part is not expensive about $30 which comes with the oil gauge as well. The expensive part is getting to it and the labor.
 
Before you guys start changing out the gauge, make sure that your thermostat is not stuck open. On cars that get low mileage per year, the thermostat may freeze up without regular use. When I bought my car in April, I noticed that the needle on the temperature gauge would go to the bottom when I was driving at night. Back then, the night time temps were in the 40's. During the day (in the mid 70's), the temperature would go to the middle and stay there.

The first thing I did when I got home was swap out the thermostat. When I took my old thermostat out, it was stuck wide open. The replacement thermostat fixed the problem.

A thermostat from Niello cost me about $38 without the club discount.
 
My gauge just doesn't move at all.. I was wondering if anyone knew..

I will be going to the NSX Tech next week and he'll address.. Just curious if anyone had this before and what the remedy was.
