I'm getting three codes with the OBD reader. PO404- Exhaust gas recirculation control circuit Range/Performance. PO405- EGR sensor A circuit low, And PO406- EGR sensor A circuit high. What should I look at and/or change 1st?

Remove the EGR and make sure it isn't carboned and the valve is closing properly. Also, make sure the intake is clean and the same.

Let me know what you find.
