Ding, Ding, Ding !!! I think we have a winner!

Was at the track this week and thought the increased oil was the fix. At the track the temp would show as it should. But when I drove around town it went back down to "cold".

Today I took the sensor out and tested it in water. It worked normally. I tested the gauge with resistors and it worked as well.

When I originally installed the sensor (1/8 NPT) into the pan (1/2 NPT) the hardware store didn't have the correct adapter. I had to use two different adapters to get it to fit. This pulled the sensor tip out of the oil bath. It was still covered with oil but wasn't getting much circulation. I do think the air flow around the pan was cooling the sensor as well.

I replaced the stacked adapters with the correct one and the sensor tip is now definitely in the bulk of the oil. I'm hoping this will work.
