Just popped a code on the Scangauge

Today my check engine light just came back on and this time I caught it and didn't press clear. It says PO401 , what does that mean ? Is it something big ? What do I need to check out ? It has ran for over 40,000 miles with it on before.
Thanks,
Raz

PO401 means low EGR flow. So your EGR valve probably needs a cleaning or replacement
