There is a two page test procedure in the manual for testing the air pump system. Criteria has to be met for the air pump to operate. It is there to clean up emissions and get the catalytic converter to operate properly to lower emissions. If a Saturn compatible scan tool is used it has an "in service bay programmed test" that tests the system. The only simple test I can tell you is the air pump itself should have .5 to 10 Ohm resistance disconnected or it is bad.
