p2195 and p0031, what's the root cause?

Hey all, my dad's 2009 v6 recently threw a CEL and traction control light as well. Got him to go and get the codes which are the p2195 and p0031. I've tried looking around but haven't seen anyone post about having these two at the same time, just separate from each other.

I know these are going to be related to the fuel&air system, but am unsure exactly where the culprit is. Is it likely to be the actual sensor, maybe wiring or a fuse? I haven't had the time to visually inspect the truck myself, so maybe once I get some time I can look around.

Any info would be greatly appreciated, thanks in advance.

 

Bump?

 

Sounds like a bad O2 sensor.

With any thing that trips the MIL it can be the complete circuit.
