'98 Honda Accord LX - egr error
My '98 Accord LX has had it's check engine light on for 5+ years now. The code always reads p0401 - insufficient EGR flow. In the past two years, I've replaced the valve three times and twice I've cleaned out the EGR ports. Replacing the valve didn't even give me a full day without the light on. The last time we did the EGR ports the light stayed off for about a week but sure enough came back on for the same code.
My boyfriend is a mechanic, but he and all the guys at the shop can not think of any other possible reasons for it. I'm not having any trouble with the car besides that I'd like to have that light turned off. Any ideas?
