Intake Flap Code?

Hello. This time I checked ross-tech wiki and my Bentley, didn't find any info. I don't think I missed it, but who knows. If anybody can shed some light on this code I got today. I replaced my EGR valve and EGR cooler last week, was running fine for a week, now this:

The PD motor modulates the position of the anti-shudder valve in order to control a bit more precisely the EGR flow. This code is telling you that there is a position sensor in relation to the anti-shudder valve and that occasionally its giving a bad value.

I'd be looking for a loose connection or bad wire.

Thanks for the tip weedeater. I cleared the code and it hasn't come back after a few errands around town.

PS, I love reston VA, nice area, specially this time of year. enjoy!
