GS 911 code 10422

Bought a 2007 R1200gs Adventure a couple of weeks ago. Periodic rough idle and slightly rich smell, otherwise running great. Connected my gs911 got fault code 10442 which basically says oxygen sensor or evap canister fuse fault. Any ideas? I am leaning toward a grounded wire or connector. It is sending pulses to the o2 sensors #1 around 684 mv #2 around 640 at idle. Cannot clear the code because it is "still present". Carbon canister was removed by previous owner, but according to Klymer manual there is some sort of sensor on the back of the air box. Haven't removed the plastic yet to inspect, that will be a project for this evening. Just wondering if somebody has seen this code before and if it is possible that there is an o2 sensor fault. New to the gs 911 and BMW's so I am learning as I go.
Thanks

Pretty sure I found it

Thanks OM. I am pretty sure I found the problem. Using combo of graph and other functions on the GS 911, looks like #2 O2 sensor is bad. On the graph the plot line for #2 is basically flat while the #1 graph varies the voltage showing peaks and valleys. Once the engine warms up the idle gets smoother. I am saying pretty sure because I am a newb with the GS 911 and still have lot to learn.
Thanks for replies

Great!
Some of those O2 sensors can be tricky to figure out. I have a Snap-On Solus diagnostic tool and have found the equation is-

1/3 the tool...

1/3 experience...

1/3 luck...
