Camry P0401 code continues ...

2 weeks after I replaced the EGR valve, the code came back.  Well, since it was not hurting anything, I kept riding it until now.  WHY?  Because our inspection tag expires at the end of August.

So two years ago, I replaced the vsv.  Unfortunately the light came back.  And last summer, as I stated above, I replaced the EGR valve.  The engine light came back again.  So the last thing I can think of is the EGR Modulator.  The modulator was about $65.00 at a local auto parts store. It took me less than 5 min. to replace it.  Hopefully, this will fix it.
