Help: Smog rejected/Clearing code (P0139)

[rbnav]

Smog was rejected today. I live in NV and we can only have one monitor off and two were off apparently (OBD CATALYST and OXY SNSR). At the time of my smog I had P0299 and P0138/9 disabled.

Does P0138/9 count as one or two monitors? If it is two, is there a way for me to disable just one, either 8 or 9? Is P0299 (underboost condition) related to either of the two monitors that were rejected during my smog? Can I enable P0299 or will this cause a CEL as well?

Any help is appreciated.

Is this my only option?

Has anyone you know with P0139 code passes smog without removing the downpipe?

Will disabling my o2 sensors on Ktuner cause my cat monitor to NEVER switch to ready status?

I can't say. What would be the issue with swapping the pipe back to stock? Did you sell it?
