Hello
I pulled the DTC codes from my taurus. I get p0401 (egr insufficient
flow) and p0402 (egr excessive flow)
Will replacing the valve solve this problem; would a simple cleaning do.
thanks for any helpful feedback

Usually caused by the dpfe sensor, Ford has had lots of problems with these,
also check for blocked egr passages.
