You need an o2 simulator to make the ecu think your B1S2 and B2S2 are plugged in. The o2 sim simulates the o2 signal so your ecu thinks everything is dandy. That should get rid of the CEL and you should pass the OBD II emissions test as long as you have no other CEL. Good luck.

tokensolutions.com has them, i do not however reccomend any simulator, rather you need a piggyback that will allow you to program and adjust settings so that your car runs at its peak, how would a company know what your climate and altitude conditions are in order to give you the correct data, point being a simulator will turn off the light, but will not fully satisfy the range of data your ecu needs.

Or you can join your bank 2 sensors to your bank 1 sensors at the ecu and never have another problem.
