That's common propaganda to get people to obey the 55 speed limit (which admittedly saves lives). It is not the most fuel-efficient speed for V-8's. 70 mph is the most fuel efficient speed for moderately aerodynamic vehicles with large engines which have been properly broken in.
States with 65 as their speed limit have improved fuel efficiency for drivers of 6 and 8 cylinder cars. 4 cylinder cars should stay below 55.
'Pay no attention to that man behind the curtain.'
You want 30MPG, you better drive like my grandma behind
The Odys do get better with age. My '99 @90k gets 24MPG loaded with a car-top carrier, 5 passengers, full of luggages, on 87 octane.
I don't see how you can give an absolute speed based on engine type for maximum fuel efficiency considering how aerodynamics and gearing are totally different for each vehicle. I'm inclined to agree more with the person who said to keep your RPMs low in overdrive. If your engine is barely working to maintain a decent highway speed your efficiency is going to be near max. This is why I like Pontiac Bonnevilles and other larger GM cars with the 3.8L V6. You can get near 30mpg on the highway with those cars because they will cruise at 70 under 2000RPM. Engine size has very little to do with it.
As you can tell- I'm new to Honda's. I'm a converted (hopefully!) Volvo guy (on # 8 or 9 now- my last 7-series) that finally got sick of working on the dang things.! :sick:
That is probably true. They are giving you a refund on the balance of your unused extended warranty. But you don't get a full refund just because you don't use your warranty. Honda would lose all kinds of money doing that.
My only point was/is, an isolated, oddball problem can become amplified in these forums to the point everyone fears the same thing will happen to them when it probably wouldn't in 200,000 miles of driving.
I can buy an OBD II compatible converter online for $150.00.
Anyway anyone ever had a converter fail? There is a Honda TSB #03073 referencing this issue. Wonder if Honda has a design problem with the converter?
It is not a drivability issue and do not live in an area with emission testing so.....but would like to replace it for a reasonable amount.
Hope someone out there has some insightful insight.
Anyway, I would have the O2 sensors checked with an oscilloscope if possible to make sure they are behaving themselves. Then if all the related components are good, you can feel safer in dropping that $150 on a converter.
good luck
this dealer/parts site has '00 convertors for $670 or so:

there are presumably some re-usable covers and bolts and gaskets although they seem to be relatively inexpensive. i imagine an independant shop would be willing to mount the stuff for a flat fee - if bj2 is not a DIYer.
there are some other sites on the web with discounted parts. i don't know if a non OEM cat. is a safe bet or not.
and it must have went far enough under the driver's seat to open the
navigation door. I didn't realize there was a door that had to be
closed. Once I closed the door on the dvd drive the nav worked fine.
This problem mostly starts after the fuel tank reaches little less than half tank. The problem becomes more frequent with less fuel remaining in the tank.
Took it to dealer twice. During the first visit, they could not reproduce the problem and returned the it. The second time, the car stalled while idling under mechanic's watch. Replaced the Air-thermo valve. The problem resurfaced the next day.
Frustrated as it's been just over a month after buying this car and all these problems! Any ideas or has anyone experienced something similar?
If so - I guess I would ask the dealership if they performed the idle learn procedure following an interruption of the supply from the battery. for example, the H&A sponsor at the top of the page includes the procedure as part of the CD changer install at step number 18 in the document:
http://www.handa-accessories.com/odyssey/03odycd.pdf
Perhaps you have a fuel pump problem or clogged fuel filter issue or contaminants in the gas tank (did someone put something in the tank?)
I guess I would take it to a different dealership for diagnosis.

I had similar problem with my Accord while driving on freeway. Luckily, I got off the freeway. After I filled up the oil to normal level, the problem solved. Hope this is your case.
So sounds like this could be a primary catalytic converter failure.
The dealer did do the initial diagnostic's, I did not confirm that they point-tested the front and rear oxygen sensors, certainly a much easier fix than the converter, but plan on asking details.
From my research looks like all cat converters sold are OBD II compatible.
Honestly, performance does not seem to be compromised at this time, so tempted to let it ride.
Yes a DI Yer.
Thanks to all for input .
I would be tempted to go aftermarket with that much of a price delta. Curious, what did they charge to read the code and give you an estimate?

I have taken the van in to be evaluated, but I was told (after the dealership had my car for 7 days), that there was no "code" coming up, and that if there were a problem, the engine light should have lit. I asked them to check the brakes for uneven or excessive wear, but there is no indication on the work order that this was done. I asked them about the possibility of the computer chip which records all the diagnostic codes being defective. How would they assure themselves that this wasn't the case? I received no answer to this.
I was told on the phone before I brought my van in, that Honda's don't break in until between 3500-5000 miles, so I shouldn't worry about the gas mileage. When I took my van in at 3450 miles, I was told that it wouldn't be broken in until between 7500-10000 miles. When I asked if Honda drove each of its models 7500 miles before they were tested by the EPA, I was told that they weren't sure of how that worked.
I took my van home, and continue to get lousy gas mileage. The problems I have described are becoming more frequent, so hopefully it will break down soon. That way the dealership shouldn't have any problem duplicating my complaints. If I'm being overly picky about gas mileage (and there isn't some underlying problem), then eventually my mpg should improve and they can tell me "I told you so." My money is on the eventual breakdown of the van.
Are there any diagnosticians out there who can come up with possible scenarios based on the symptoms of my van's problem(s)? I fear that service departments of dealerships have become staffed by technicians who can only act (or think) if they are flashed some code on a diagnostic screen.
I love everything else about this van, but the gas cost is eating my lunch!
Sulphur smell, hesitation, and/or bad mileage are classic symptoms of bad O2 sensor and/or bad or plugged catalytic converter. Not sure what would cause your tranny troubles but hopefully that helps some. I suppose a plugged cat could confuse the hell out of the tranny if the exhaust is backed up to the point the engine is rendered powerless. Certainly sounds like an emissions systems issue.
good luck
Based on the Honda technician’s statement and posts in this forum, Honda has known about this problem for some time but are either unwilling, or unable, to correct it back at the manufacturing plant.
My confidence in the high quality, one of Honda’s mantras, of the Odyssey has been brought down to earth.
If an average person drives 12000 miles a year. Then driving 65miles vs 55miles he would save 34 hours of his time (the difference is greater if the average speed is lower and you also going 10 miles over limit)
For say 100million people driving or beeing driven, that would save 340 thousand people-years. That means that raising speed limit 10mph is equivalent to adding one third of a million of productive workers into economy for free! Or 11,000 times 35 year long lifes spent commuting.
So, if driving 65 vs 55 saves less then 11,000 lives per year cut short (And I do not believe that one bit, as I did drive on roads with no speed limit, and they are doing just fine thank you) then it is not worth it. We waste more lifes sitting stuck in traffic.
And this oil economy thing is also bogus. Just think how much more productive this country can be if we do not waste 340,000 people sitting on the road driving slowly.
I'm not sure what any of this has to do with an oil economy. People are not wasting time in their cars driving 55. They are wasting time poking along at 7.5mph during rush hour on overclogged freeways and local roads. You can raise the limits to infinity billion to the seventh power and still never affect the major traffic flows in any way. Except maybe to annoy them by reminding them that if there were no traffic they could go as fast as they wanted to.
Partially because 20% of highway capacity and untold amount of road maintenance dollars are spend on the thoroughly misguided attempt to force us to carpool and to build insanely expensive carpool-to-carpool interchange lines etc.
If every car could spend 20% of time less on the road (when the road is unclogged), and the highways were 20% wider, there would be almost 50% less cars per lane, and many roads would not become clogged at all. It does take very few extra cars to grind a road to a crawl.
Socialism in action.
I live in the San Francisco Bay area and commute to work at 80mph every day (just like almost every other car), and have not had a single traffic ticket or accident in 12 years. I calculated that I do save 20 hours a year vs driving at a speed limit.
More then 2 full working days a year is wasted for each worker here who drives 65.
Minimal productivity of my engineers is about a thousand dollars a day. So just my little group is loosing $40K a year in lost productivity for the speed limit.
I know the owners manual tells you where the temperature sensor is. I don't remember exactly what it said, but it's somewhere under one of the bumpers, I think.
PO420 is listed as "Catalytic system Efficiency below Threshold. (Bank no. 1)"
Like I stated earlier there is a TSB on this issue referencing PO420, so wonder what Honda is seeing on this problem.
The dealer charged $63.91 for reading the code. Do not know if they checked each sensor.
There is a big price differential and honestly if I replace will likely go after-market and DIY. I will have the sensors checked before I spring for the converter.
And, the sensor is behind the front bumper, in front of the radiator. I haven't gone to look for it though.

I would think CA urban areas would not be much better off, but I guess certain parts are lucky even at rush hour.
If there is credibility in the under 55mph for 4cylinder cars and 70 mpg for V8, then it stands to reason by interpolation/extrapolation that for V6, it would be between 55 and 70, and 55 - 60 lies in that range.
Actually there is more to it that. It depends on many factors such the engine discplacements within each class of 4, 6 or 8 cylinder engines; OHC vs OHV, etc
Just using some logic from my engineering background..
Did they check fuel pump pressure?
"This problem mostly starts after the fuel tank reaches little less than half tank. The problem becomes more frequent with less fuel remaining in the tank."
Did this problem occur after a tank fill-up in case it is bad gas with water? The half tank point sounds like water or something in the tank. I would consider having the tank flushed/emptied and refilled with new gas... from a different gas station. Install a new gas filter in the process.
I have had very few problems with the 2002 Odyssey. As of June 2005 I have 125,000 kms (76.300 miles). Replace, on warranty, rear seat fabric in 2002,due to flaw. Change on warranty, rollers on doors, in 2003; suggest they just oil them. Replaced windshield twice, on warranty, in 2002, due to top rubber moulding loose.
The transmission recall added just the 2nd gear oiler. The front brake pads were replaced at 95,000 kms (59,600 miles) and read pads and rotors replaced at 115,000 kms (71,500 miles). I am currently on my 2nd set of Semmary tires and will mostly likely replace these at 140,000 kms (the 1st ones replaced at 72,000 but could have gone longer {worried about snow traction)). Replace at 94,800 kms, on warranty when engine light came on, 'by-pass solenoid and two-way valve; evap bypass control solenoid valve.Replace, not on warrenty RW/OD/PI/S2 B/P Sol. Replaced gas cap as engine light came on. I feel that these emission items go sometimes and you must replace them when they age. My 1992 Taurus had a lot more problems (I traded in the Taurus at 283,000 kms, for the Odyssey). I find the van rides great, but you must keep you tire pressures at 36 pst, cold. I check mine once a month before the day warms up. I have been down to New Brunswick, Virginia, Arkansas 3 times, Michigan 4 times and Montreal 12 times. Other then this I am driving the van in city/rual driving about 600 kms per week.
Another thing I do maintenance By-The-Book at the Honda dealer; no skipping.
I hear you. It is quite bad here in many spots - the trick for me is to avoid that. A lot of folks do get stuck.
But still - it does not take a lot of cars to slow everybody down, and if some cars passed by faster in the morning, jam will start later (they are off the road by then) and end earlier.
And money saved on carpool lanes can be used to build better intersections while opening up a lot of underused highway capacity.
Personally, I would be all for raising the speed limit. I generally ignore them on major highways and stay in the 70mph range anyway. It was refreshing to travel to places where that WAS actually the limit. It's just unfortunate that the traffic here would not be able to take much advantage.
Dial that cell phone, put on your make-up or have a flat tire and see how well you "think" you can handle that Ody!
Be kind and let people merge when they need to get over a lane will make traffic flow better. My 2 cents.
That is exacty what people said when cars started to drive faster then 30mph.
Nothing wrong will happen at 80+ mph in a modern vehicle if you keep your distance and your eyes open. Nothing. Every single car on my road to work every single day goes 75+. Watch total lack of chaos.
There are plenty of highways in the world with no limitation. People survive just fine. No rise in accidents, no nothing.
"Speed kills" is a blatant lie and misuse of statistics. For example, if they say that 80% of cars involved in a collision were exceeding speed limit, that really means that it is safer to drive fast - as 95% of the cars on the road are exceeding speed limit around here. So you get a lower percentage of them involved in an accident. The fact is - those statistics are unrelated.
You are right on about good driving habits and common courtesy. That is the real issue.
We bought odyssey in 2000. Had regular maintenance until now and no problems with sliding doors. But yesterday new problem pops up with sliding doors which are not opening with remote control (or) front panel switches.
We are able to open doors manually by using force which the dealer says shouldn't be the case. Is it the case?
Please pos/reply if you had any problems related with sliding doors not opening as designed.
Did you or the dealer checked the fuses?
It was a refreshing thing to switch from my previous "Fix Or Repair Daily" Windstar to a trouble free Ody which I have never taken back to the dealer for repairs or PM(since I do these myself).
Continue to enjoy your Ody! It handles like a great handling sport car.
I have driven a vehicle at speeds exceeding 120 mph, never had a speeding ticket or an accident while driving at those speeds, does not mean it is safer to drive at 120 mph than 55 mph?
Sorry, not buying that.
I have never had a vehicle up until now that has had one strut leaking let alone both at the same time.
Anyone else experienced this?
anyone know if the warranty should cover the wireless headphones that come with the RES (dvd player)?
the headphones are pretty cheap and don't hold the batteries very well.
can anyone assist?
Thanks
:confuse:
2014 Malibu 2LT, 2015 Cruze 2LT,
Just got an '05 Ody Touring (with 90 days free XM).
I want to plug my iPod into the AUX port. But the dealer says I cannot use the AUX if XM is enabled.
Anyone know if this is true or not? If it is, is there any way to have BOTH XM and my iPod working?
Many thanks.
