P0401 indicates an insufficient flow of gases through the EGR system. While Honda EGR valves occassionally fail, your first step should be to check if the EGR is operating when vacuum is applied. If so, remove it and clean the orifice with brake cleaner. While you have it off, clean the intake porting with carb cleaner and a stiff wire brush. Carbon build up in either the EGR or the intake will set this code.
