I do like the idea of a 3 wire sensor with built in heater.

What would be the signs of a failing ECU? I have opened mine (0 280 800 055) and visually nothing looks burnt or failed but I have not yet sent it out to be bench tested.

Since the ECU is a complex electronic unit, there are many possible symptoms that can result from a faulty ECU.
Check out this thread where MySocal911 shows how to check the ECU pins:
