An E01 is a thermistor open code. That is key number 21 on the part diagram here.

Does this correct an E05 error? Stack flue temp is at 70 when E05 shuts everything down.

Hi, Yes, replacing this sensor will correct the issue that you're having that is causing the error code to appear.

Can I test this sensor with an OHM meter? What reading would indicate a bad sensor?

Hi. Resistance should be 3.5-4.0 megaohms, if not it will need to be replaced. .

I am having an intermittent E05 error code on a Pentair Mastertemp 400. Any suggestions what I should look at/for? Is this the correct stack flu sensor for that heater?

Hi, Richard. That error message indicates a faulty Stack Flue Temp Sensor - 42002-0024S.
