Mirage EGR Code P0401

CEL light kicked on and had this code when scanned. (EGR flow insufficient) Might anyone know what the most likley cause would be? Does this car have an EGR flow sensor or does this get accomplished via the O2 sens? Thanks in advance for any help.

I had the same code and would also like to know the answer. Does you car drink gas like a 454, cause mine does.

I'd start by checking the vac line to the EGR solenoid, then the solenoid, then finally the EGR valve itself.
