What does EGR flow insuffient code p0401 mean on a Honda accord 1996?

EGR stands for Exhaust Gas Recirculation, which basically sends some of the exhaust back into the engine cylinder again. Your error means that there isn't enough of the exhaust gas making it back to the intake manifold. The first thing I'd check is the tubes coming off of the EGR valve to make sure they aren't clogged or broken. Then I'd check the EGR valve itself and the throttle body. The problem is usually: 1.) Carbon buildup causing a clogging. 2.) Broken hoses. 3.) Broken Valve.
