I have a 2011 JK that has thrown 4 codes, P0031, P0037,P0051, P0057, which is all the O2 sensors and those have all been changed at the same time and as lei type as 6 months ago. I have checked everything that I can think of and can’t find any reason why it would error all 4 sensors at the same time. Would appreciate any thoughts as to what to check to correct this.

Bosch and I had check the ground and found the ground wire is in good condition and tight.
I haven't heard very good about Bosch, I and others have used NTK. Also if you still have the junk factory battery clamps replace them with some good heavy duty ones.
These Jeeps are electrical nightmares and the electronics have to have a good ground.

I double checked the grounds today and couldn’t find any issues, unless there is another ground that I don’t see. The one I check is the one on the right bank between the heat shield and engine block. I can see if one sensor goes bad, but all 4 at the same time would seem unlikely.
What about if I run a new ground from engine block to the frame, do you think that would help?
It wouldn't hurt anything, even clean the ground from battery cable to the engine block.
