My tuner turned off my rear o2 sensors but I know power is still sent to them from the computer. Don't ask me about that short lol. Yesterday I unplugged the o2 sensor and zip tied the wire harness up, and I got two codes p1132 & p1152. Both of these codes refer to rear o2 sensors. Plugged them back in with the wire cut from the sensor to the plug and no more codes and car runs great? Can someone explain how that all works? :bash:
Turning off Rear o2 sensors in Tune

The rear O2s don't affect driveability. Only the fronts do that. The rears are there to make sure the cats are working properly. More then likely he didn't turn everything off. I know on mine there were three scalars I needed to turn off. I can unplug my rear O2s and I don't get any codes.
