If that's all good then it's probably the power steering pressure switch. They sell them at auto parts stores for about $35 and it's a 5 min swap.
Is there a DIY anywhere for doing this swap? I've got this same code, with a few weeks after new pump and plenty of fluid still.

Any help would be appreciated.
