You can buy o2 sensor simulators. I can't recall if the rear o2 sensors are heated or not, but if they are you will need something to simulate the heater so that circuit doesn't throw a CEL.. As we all know the rear o2 sensors are there just to make sure the cats are doing their thing, the front o2 sensors are what actually control A/F ratio.
