2000 Odyssey P420 code? HELP!

TomBauer · Feb 7, 2005

2000 Odyssey 60,000 is getting a P420. 1st the check engine light can on then went of after a week or so. I thought it had to due with the fuel cap. Then after a few days it came back on. Now my wife calls and says it is flashing maint required. She take it to a Midas dealer to have diagnostics ran and it gives a code of P420. They say to do a Fuel injector cleaning? I call a Honda dealer and they say EGR? I look up the code and it has to do with the CAT? WTF?

Midas said that a ERG won't help. I asked why, they say because the throttle shows in the open position at idea and that when giving it gas it takes a while for it to catch up? I have no clue.

I then see this...

Occasional problems on this vehicle are failure of the Exhaust Gas Recirculation (EGR) Valve Passages or the EGR valve. The cost to repair the EGR Passages and the EGR Valve is estimated at $74.08 for parts and $195.00 for labor. The cost to repair only the EGR valve is estimated at $169.00 for the EGR Valve and $32.50 labor. Honda has extended the warranty on EGR trouble codes to 8 years or 80,000 miles. All prices are estimates based on $65 per flat rate hour and do not include diagnostic time or any applicable sales tax.

Any ideas?

Thank you

whatever you do, do not trust midas!!!!. The maintenance light is just a reminder to do maintenance so I would not worry about that. The owners manual can tell you how to reset it.

In terms of the check engine light, I would take it to a dealer or a honda mechanic, otherwise, Midas is going to just start throwing parts at it until you are broke. By the way, their fuel injection cleaner is not worth it, for the money you are better off buying Chevron Techron injector cleaner. It could be your EGR or your cat. In either case get it checked and diagnosed by a Honda mechanic whether it be the dealer or an independent.

I know lots of people with bad luck with Midas, one time Midas tried to sell my dad a new exhause system from the exhaust manifold back due to a check engine light code, needless to say all his car needed was a new 02 sensor.

Did the Honda dealer really say this? There has been some discussion regarding the P0420 code and whether the EGR ports being clogged are at all related. I would be real interested in what you end up finding on this problem.

BTW, I have the EGR cleaning procedure if you want to attempt it yourself. Just PM me with your e-mail address and I will send it to you. You shouldn't have to do it yourself since it's covered by either your emmisons warranty or the recall notice on the EGR tube.

UPDATE:

I did take this to our HONDA dealer and it was related to the CAT.
To my surprise all the work was covered. NOT ONE PENNY PAID TO THE DEALER.
