It's on the front outside of the air sensor assembly just above the intake manifold. I think it is black plastic and it has wiring that runs to a connector just to the outside of the idle valve. It's function is to tell the brain whether the system is at full throttle or idle or something in between. I believe that its main function is so that the EHA can go to "full enrich" at full throttle.
