Ok...that is close enough for the gauge to be used ..
Now, compare the ohm resistance across the blu 2 wire sensor
[ unplugged] with this chart, using the dash gauge readings as your temp input.
Remember , each index mark on the gauge is 20C. [ I see some guys read 105C as 85c , not knowing that]
Temp Ohms:
60C- 900-1800 ohms
85C- 460-650
100C- 300-400
* note
You want the highest temp reading here for testing the sensors accuracy...the lower temps ones mean very little.....
