P1404 Trouble Code...

As an update to a previous thread (2001 Impala...) --
Had the codes read tonight and it came up with P1404 -- EGR Pintle Position Voltage Error

appearance that the pintle position has to be recalibrated or the EGR valve replaced.
Question: Is there a way to service the EGR valve and possibly cleanup any gunk from the internals? Is this a replacement or recalibrtion fix only? Any other suggestions?
Thanks, Gary

Take it off clean up the pintle and seat area of the manifold, use brake clean.
