02's

[gmforlife]

I have been trying to research how to turn off the rear 02's on my 2004 sierra, some people are turning off enable 137-161, is that what i'm supposed to do. Cause i'm getting some trouble codes after doing my 80 swap, and i believe these are the rears.[PCM] P0156 - HO2S Circuit Bank 2 Sensor 2 (Old) (Immature)
[PCM] P0157 - HO2S Circuit Low Voltage Bank 2 Sensor 2 (Old) (Immature).

Let me know which ones to turn off, and will it affect anything? The truck is tuned pretty well right now, and will be getting a catless y and a WB soon so i just wanna get rid of the rear's for now cause i think they are messin up

so any s1's leave them the way they are, s2's enable off correct?
