98 Accord 401 Insufficient EGR flow Sign In

This 1998 Honda Accord 3.0L V-6 with 164,000 miles is showing Code 401 EGR Flow Insufficient.

EGR valve has been replaced, and the code cleared. Fewer than 5 miles later the code came back up.

What else can be causing this malfunction ?

Might wanna call your local dealer and see if there is an open recall on your vehicle for the EGR system ports clogging (99-085). Have your VIN ready when you call.

Re: 98 Accord 401 Insufficient EGR flow Sign In

Thanks. I'll give'em a call tomorrow, but what is (99-085)? I sprayed a can of carb cleaner in the port to see if that might help. I'll let you know about that tomorrow.

Re: 98 Accord 401 Insufficient EGR flow Sign In

There were several recalls on various models, and ours was included.

We flushed with two carb cleaners, small brushes and high pressure air. All kinds of corruption was flushed out, and so far the code has not come back.

If it does, I'm going to take the EGR mount/manifold out and clean it from the inside.

Your direction was spot-on.

Thanks.

You really should remove the upper intake to access the carboned up holes. They usually have to be dug out with a screwdriver or drill because the stuff gets pretty hard.

Re: 98 Accord 401 Insufficient EGR flow Sign In

hammer hit it on the head,both 4 & 6 cyl's have the same problem with the egr ports getting plugged with carbon stopping egr flow.quick way to check is remove the valve & start the engine,if it idles its plugged,it'llbe loud from exaust escaping from the open port,now while its idling feel which port the exaust is
coming from and concentrate on the other port (vacuum port).now turn it off and soak the vacuum port with carb cleaner or even wd 40 and allow it to soak a bit then attack it with a small flexable cable ,i always use a ft. of speedo cable and a very slow drill to get down in the curvy port...works every time.. good luck

Re: 98 Accord 401 Insufficient EGR flow Sign In

Its not really necessary to explain a repair to someone who just reported that they FIXED the problem. If you just like to talk to hear yourself talk by all means write yourself a letter and mail it to yourself. You'd be your own pen pal, biggest fan and president of your own fan club all at the same time. Sounds like a lot of fun. You are dragging up old posts left and right, throwing out ideas at random that are already covered by other posters very clearly, and in general making yourself an irritation. I'd suggest treading lightly. Any moderator in here can at any time press one button and ban not only your user name but the IP address your computer uses to log online.

Including me.

If there is an open recall on this vehicle, then why didn't you let the techs at the dealer fix it. It's an emission's recall and you don't have to pay.

Re: 98 Accord 401 Insufficient EGR flow Sign In

To say I'm confused by your post is an understatement.

If I've done or posted anything to "iritate" anyone here, I apologize.

I don't know what posts I've dragged up or what repair has been FIXED for which I've asked a repeated question.

I have had an EGR problem with a Ford for which the PTFE sensor was the problem.

If you'll meet me in email or do it here in an open forum and explain any problem I've caused, I'll change the way I do things. The last thing I want to do is iritate someone, particularly someone of whom I've asked assistance.

Please accept my apology.

I don't believe Nicks post was addressed to you. It was the post before his.

I'm relieved, to say the least. I wear a guilty conscience most days...so it doesn't take much to make me look in the morror.

Thanks

Re: 98 Accord 401 Insufficient EGR flow Sign In

WHOPEE! That was the fix. It took some delicate twisting and turning to guide the cable through the port hole - it is verrrry small, but it worked. It was clogged almost completely, but it's now clear and the code is gone.

Put another feather in your hat.

Passed state inspection, and we can all breathe easier thanks to CARJUNKY! and Hammer Time.
