Throwing one of these on my 4.0. Looks like a straightforward 02 sensor code (AFAIK these might damn well be original at 230k miles). But the live data is odd (see screenshots). I get reasonable freeze frame fuel trims, but the live trims are way off on all the sensors, so I don't know what to make of that. Only other thing that jumps out is the ECT, which I hadn't noticed before, isn't getting above 81' C or so. I don't think that would have an effect on these readings once the system was in closed loop mode, but maybe? I guess the T-stat is the next thing to swap out anyway...Thoughts?
I'm going to swap out the pass side sensor tomorrow and see what happens.
