    Rear heated 02 sensor bank 2 question

    I had offroad down pipes on my ecoboost, but I took them off & put the stockers back on because of the substantial loss in torque I was experiencing. That was last night. This morning, I drive the truck and get a CEL, pull the code (Diablosport tuner) and it says P0161. I know the sensor is plugged in and tightened down.

    Do I have to put a new one on it, or should I switch the two rear sides and see if it switches to bank 1?

    Ecm flash 13e03b fixed that iirc. It's '13 specific, fixes the downstream o2 from never getting to a "ready" state.

      I've heard some people disconnect the battery for corrections, don't know how to flash the ECM though.
