Erroneous Low Coolant Warning
Yesterday I swapped my coolant tank with a NIB replacement from Fred Beans. Immediately started getting low coolant messages. Reset all of the codes, but still getting. Double-checked the electrical connection, made sure the sensor is fully inserted, not bent, etc. Mixture is good, engine runs cool, circulates fine through heater, etc. I reused the original sensor, so I know it works. Is there another reset of this sensor that can be done? I was not getting it before I swapped tanks.

I don't think this is your problem, but this old TSB covers a similar problem and identifies the correct installation height of the rear of the tank. If the rear is too high, the float may report a low coolant condition.

Other than that, your low coolant switch could be shorted causing false condition.
