P0401, EGR flow insufficient
Hi,
my 2001 accord was diagnosed with egr flow problem. it is out of the extened warranty. i cleaned the egr valve and put a new gasket recommended by a friend but the code p0401 came back. from reading posts in various places, it's recommended to celan the egr ports and/or change the DPFE sensor. does anyone know where the egr ports and DPFE sensor are located?
thanks

there is a big post with some pictures in our DIY section that should show you exactly how to do that.... it probably is clogged egr ports (most likely) but it's not to hard to repair...
