You shouldn't need to replace the rear O2 sensor with a P1273 code. The fuel pressure should be checked as well as a leakdown test when diagnosing an A/F sensor or O2 sensor code. Nissan released a TSB (#NTB04-126) back in 2004 regarding clearing the ECM self-learning; they should have been aware of it. Sounds like the tech working on it saw the code and "guessed" at what the "fix" was without following the diagnostic procedure to correctly isolate the problem.
