Shows code P450, which is EVAP pressure sensor switch. Switch checks out okay. Where do I go from here?

If the pressure sensor itself is okay, check the wiring back to the PCM, does it show rising/falling tank pressure on a scan tool while testing? It can also mean that it tried to do a test and the purge solenoid was commanded open but it did not actually open so the PCM thinks the sensor must be bad.
If you have a scan tool run a couple EVAP tests and see what does/does not work.
