New OBD2 code p0140...mystery o2? 850 1997

Does the 97 have a different O2 sensor than the rest of the 850s?

I just took mine off, and compared it to my new one, and they're two completely different lengths. And I know it's the rear one because it's the one further along on the exhaust.

BUT whats weird is, the videos I've seen show the O2 sensor being right above a plate that you unbolt (with 12 mm socket), but mine isn't. It's maybe 6 inches away from the front O2 sensor.

I did some researching (just now) and it appears there are 2 different varieties. One is much cheaper (mine is! yay!).

Just hope I can return it
