I've been getting this code and am a little perplexed, for I have the rear O2s turned off in my tune and have never had this code pop up before!?!
Do the sensors still provide voltage feedback even though they are "turned off" in the tune?
I'm just wondering if they still need to be in working order even when they are turned off via CMR.
