So just cut a splice both white and black wires and install the resistor between both wires vs in line with just one wire?
it hardly freezes here very often but if you have an ohm meter to read the resistance of the sensor in your damaged tank maybe using different temp ice water we could try to find a thermistor that would work properly in the system, if not no big deal.
I will try the 10k ohm resistor first and report back.
One other thing, this code is new. I am not sure what this code is. Driver detection?
