It could be the sensor rod is too long. Clean the area in the manifold very good. I sometimes shave a little from the rod so the code will go away. Good luck

Well heres the deal i took off the vaccum hose to the egr and at city speeds the light isnt comming on i havent tried the highway cuz im surs the light will come on sayin its not opening. So could it be some kind of vaccum regulator keeping the egr open just a little bit cuz my truck runs great, but if its open to far it runs like crap.

Suggested Repair

Clean the EGR passage area in the manifold thoroughly. Check whether the EGR position sensor rod is too long; the expert sometimes shortens the rod slightly so the code clears. Also verify the vacuum regulator is not holding the EGR valve slightly open.

Conversation Summary

The owner of a 1995 Ford F-150 has a recurring EGR code after replacing the position sensor. Idle is fine and slight vacuum seems present at the EGR. The expert said the sensor rod may be too long and recommended cleaning the manifold area, sometimes shortening the rod slightly. The owner later disconnected the EGR vacuum hose and the light stayed off at city speeds, and asked whether a vacuum regulator could be holding the valve slightly open.
