Just installed AS&M long tubes with no cats. I need to delete the rear O2's. There is a bunch of rear O2 codes. Which ones need to be turned off? You can list the number of the codes or please explain which ones there are.

Thanks,
Sean

 

all of them, anything that say B1S2 or B2S2, seems like there are 6 or 8 of them

 

These codes are for the drivers side rear O2 (B1S2).

P0137
P0138
P0140
P0141

These codes are for passenger side rear O2 (B2S2).

P0157
P0158
P0160
P0161

Just toggle them all to Type X in EDIT and you'll be set. Make sure those numbers are for Bank 1 Sensor 2 and Bank 2 Sensor 2 before turning them off.

 

You may also have to set P0420 and P0430 these are cat efficency codes. They compare front to rear O2 readings

 

Thanks guys!

Sean
