Question P0137

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.

Re: P0137

maybe a wire cooked or broke or burnt/ if the code didnt show beofre its not the tune. many run with them off without a code.

Re: P0137

Just found out that they still need to be in working order to send feeback to the ECU, even though certain codes have been turned off via the tune...gonna check the connections.
