Assistance appreciated - chasing codes

Is that the freeze frame?

Yeah, I may have put them up in the wrong order though

The order doesn't matter. What's weird is that it's in open loop but throwing an o2 code. If your scanner can graph live data, show us the b1s1 and b2s2 graphs when idling after warmed up.

Thanks...I'll get them up as soon as I have a second

So based on what I'm seeing off my scanner I have:

IGN ADV: 24.9
LT FTRM1(%): 0.0
LT FTRM2(%): -1.6
MAF (LB/M): 0.79
MAP ("HG): 10.6
MIL STATUS: ON
O2S11(V): 0.42
O2S12(V): 0.055
O2S21(V): 0.045
O2S22(V): 0.040
OBD2 STAT: CA
PTO STATUS: Dise
ST FTRM11(%): 0.0
ST FTRM21(%): 0.0
ST FTRM1(%): 0.0
ST FRRM1(%): 0.0
VEH SPEED (MPH): 0

I can see based off this the higher than other voltage on O2S11 but not sure where it would be coming from

swap the sensor and see if the problem follows the sensor or remains in the same position

I’m not an expert but I think one of your cats may have a cat going out or plugged up.

Not sure if that would be helpful as I recently swapped the sensor for a new OEM one about a week ago and the code was absent for a few days but returned.

Your b1s1 & b2s1 (pre cat) should be constantly switching between ~0.1 & ~0.7

Your b1s2 & b2s2 (post cat) should be petty steady

The graphs should look something like the top two here:

I mean swap left/right sides, take the one from the drivers side and put it on the passenger side

If your sensors are good and these numbers are accurate, this is definitely a catalytic converter issue.
