tags. Unfortunately, the check engine light wouldn't stay off and it had code P0401 -- Exhaust Gas Recirculation, Flow Insufficient.After paying a mechanic to install a new EGR valve and catalytic converter,1 and trying more expensive gas and gas cleaner additives, the code still showed up. It was https://brentlogan.com/2011/01/2001-honda-odyssey-egr-fix-for-p0401-code/ time to take matters into my own hands.But first, I needed some information. I searched YouTube and found the following video:I also found Honda's service bulletin 00-009 which has been superseded by Honda service bulletin 05-026.Ordinarily, any instructions that tell me to remove big hunks of metal from my car's engine, do something to them, and then put them back on would scare me off. However, having to pay someone more money to fix my car honda odyssey and/or not getting my car fixed in time before the trip permit expired scared me more.I forged ahead, basically following the method from the YouTube video, informed by the steps of the service bulletin and the torque specs and reassembly instructions from an online Chilton's manual.Any time I attempt a fix, I take lots of pictures and take notes so I can put it back together. Some of the pictures are attached below. I hope p0401 honda odyssey to be able to update this with a picture of my OBD II checker showing no errors after a complete drive cycle.Wish me luck!Update: I should "clear the air" a little about where I cleaned the intake manifold. I used the carburetor cleaner in the garage with the door open, not in the kitchen sink. You don't want to use that stuff in an enclosed space. I used the kitchen sink to rinse out the manifold when I was done with the carburetor cleaner.Update 2: The fix worked! Woo hoo! I'm not complaining; I don't think we've had problems with either of these for over 220,000 miles.↩ Author: Brent Logan Engineer. Lawyer. WordPress geek. Longboarder. Blood donor. Snapshooter.

I'm hoping to hear good news from your test. It looks like you did indeed find the problem. I loved the egg carton idea.This is so typical of what happens when you take a car in for service. They always do the easy (for them) and often expensive (for you) part replacement first.Reply Brent Logan says: January 16, 2011 a
