0401 - EGR Insufficient flow.

check the green vacuum tube going to the EGR for cracks, breaks, brittle areas (careful, you can cnap this entirely if you stress it)

Check the rubber boot on the end that plugs in to the EGR nipple.. Check for splits, tears, or pinholes.

Check for EGR operation. (Start car.. remove green vacuum tube/rubber elbow from EGR. Suck on EGR metal nipple. Car SHOULD stumble.

Check/clean the EGR ports in between the TB(Throttle Body) and the UIM. Purchase a new TB gasket for replacement (you'll need it if you remove the TB).

There are ample how-tos on the site under Duratec Maintenance, in the FAQ.

I did the test thingy, and the car did not react to my input. i did however hear the rubber diaphragm inside the EGR move with the suction, so i know thats working.Ill just have to try and clean it on monday when i can get in the shop.if that dont work, ill try replaceing the DPFE and see if that works

Just a note of caution about the OBD II world, don't mess with the EGR except keep it working properly. Those days of blocking EGR doesn't fly anymore, does just the opposite.



thats what i said when i heard of the EGR capping

Thank you all for trying to help!!
