P0401 is not necesarily a faulty EGR. On many models it means the EGR passages downstream from the EGR are blocked. P0401 means insufficient EGR flow, but not necesarily a faulty EGR valve.
You need to advise what year/trim Accord you have for better help.

Others w/ more knowledge of V6's will help, but my recollection from previous posts is the intake manifold must be removed to access all the passages.
