if I put the sensor on a meter and it reads 4.6 meg ohms at room temperature
Can you link to the data for the thermistor? I thought the Dyze thermistor was 500K at 25C, which means at a room temperature of around 20C its resistance should be will below 4.6Mohms.

there are 2 one 300 and one 500

I am wondering about a possible source for my temperature display to register values that fluctuate constantly between random values between -10 to +5 degrees of set point. the issue happened 10 hrs in to my first long print, no issues with the print however. my first guess was an overheat in the board, but I have a big fan on the board and I calibrated the board temp sensor. strangely it says the board is running at 24c which is lower than the 30ish that is normal.

I see your point, however I was getting excellent stable temperature until I got well into the long print. then the changes started. I have done the Hotend tuning and the stability is better but no as good as it was. perhaps there is some sort of break in.
