My air pump acts up in winter and now the bearing is going (my car sounds like it has a supercharger some mornings). So now I have two options: the easy way is to replace it, not cheap, and I haven't been able to find anything used that would fit.

Option two is to 'bypass' it, which would mean deceiving the OBDII system into thinking that the pump was working. So my question is, what input tells OBDII that the pump is working? There must be an air flow switch or a pressure switch to indicate that the pump ran as requested. If I bypass that switch with a relay wired into the air pump power I should be good to go, right?
