Secondary Air Injection removal

I know it seems kinda meaningless but how simple would it be to remove the secondary air injection pump and valve, make a block-off plate and wire up a simple circuit that produces .100V for the pre-cat 02 sensors upon pump activation to make it look like thing is working. I already have the plate on and I have a DPDT relay all wired up but I dont know how to make a ciruit that uses a good regulated 5volts and steps it down to .100v, got any ideas?
