According to http://www.scangauge.com/support/pdfs/XGAUGE.pdf
you can configure the XGAUGE feature to monitor the O2 sensor values.
I suppose that if you have a wiring problem, the O2 value for this sensor will remain at a constant value rather than constantly fluctuating as the ECM varies the A/F mixtures.
I was also wondering if the correct sensor was replaced. I once replaced the wrong O2 sensor in a Honda because I wasn't aware there were others on this particular model.
