There is a very common problem with early Pacificas and several other year models of other Chrysler cars and vans that causes the codes P0032 and P0403 to set and its not due to a failing HO2S sensor or a bad EGR solenoid. It is in most cases caused by a bad ground to the Exhaust Gas Recirculation (EGR) solenoid. The ground you need to check, at least on the Pacificas, is the G100 ground located on the left frame rail below the battery. Make sure its clean and tight with no signs of corrosion. They are known to break and come loose.
