Hi,

Have a 2000 LX. As of late, I hear a
strange kind of grinding noise, come from
the engine, when I'm driving above 50 MPH.

i.e. under 50, that noise doesn't appear, but
at and above 50 it is quite noticable.

I suspect it has to do with some kind of gear
change at or about 50, but I'm not sure. Also, this noise is new. It wasn't there before and it is clearly a low level grinding noise that is in addition to the normal engine hum.

While we've scheduled a maintenance check with the dealer, I'd like to hear if anyone else has experienced this and if anyone has any info/advice to share.

Thanks

James

Hi James. Have this problem on my '01 EX. I wouldn't call it loud but it is noticeable. Right around 50-55 mph, not below or above. I'm only able to hear it when I'm alone in the van. But at least I know it's not my imagination now. Am due to take it in to the dealer to shut off the maint req light (unless anyone here knows how to diy.) Will mention it to them and see what they say. We can compare notes on our respective dealer experiences.

Don't know about the noise... my Ody has the infamous tranny "grinding" noise at low rpm's. It is very noticable at 45-50 mph.

You can reset the Maintenance light by the following:

Engine off, press and hold the trip odometer reset button. While holding down this button, put key in ignition and turn to ON position (do not start engine). Continue holding button down while Maintenance light blinks. Light will blink for approx. 10 seconds. When it stops blinking, release button and you're ready to go. Smile at how much time you saved instead of going to dealer.


Note: this should only be performed if the light came on because of a do-it-yourself job... like an oil change. If this light came on by itself, you should get the dealer to check on it.

Hey. Thanks a lot.
You did save me the time and trouble of taking it in (and likely leaving it for a while)for something really minor. I know it's fine to do it myself because I just had it in for service and had them do the maintenance early. Appreciate the help.

You're welcome, but my services aren't free. Let me take a drive in your '66 and we'll call it even... ?

Don't I wish I could. Had to give it up when I had kids. Not very practical, safe, etc. Boy, do I miss it on these summer nights! Would you settle for a look at it? Afraid a picture is all I have left...

Oops. Ok, this is obviously not it. Let me work on this.
Tech savvy I'm not. But I guess you already know that since I had to ask how to get my service light off.

Hi,

James here again. Thanks everyone for the
info. I will get to the bottom of the noise.

I took the van to a Honda dealer here in
Sunnyvale, and told them explictly about
the problem. i.e. grinding when the speed
gets UP to and above 50MPH. Definitely
happens during acceleration etc. No noise
during braking.

So, what did they do after keeping the van
in the shop for the better part of the day?
Deny that there was any grinding noise but
replaced the breakpads (so they say) because
there was an odd noise during braking!

Of course, when I was driving the thing
home, and hit 50+, the noise was clearly
audible.

Anyone know of a good, reputable dealer
or service center in the San Francisco
Bay area that can address this issue?

James

Looks incredible! I hope you at least sent it to a good home. Sorry you had to part with it. Personally, I would have told the kids that they'd have to walk... I'm NOT getting rid of the car!

LOL. Glad you liked it. It was a lot of fun. We sold it to a man that restores classic mustangs and then sells them. It did need some work (which was the main reason it had to go -- too time intensive & too expensive) but, by the time he got through it was probably close to perfect. I was only the 2nd owner and it had belonged to a woman who bought it new in Virginia. I did cry when we sold it (that's a girl for you.) Maybe someday I'll have another one, although it's starting to seem improbable to have a car that's the same age as you are
In the end, I'm happier to have the kids (most days anyway
Well, we're WAAAAY off topic - thanks for indulging some fond memories.
BTW, I successfully turned of the maint req light in my ody this morning -- you're the man! Thanks again.

While I was driving by myself without the radio on, I heard this sound. Only audible upon accelerating, no sound when foot off the gas pedal. I read the threads about the fix, but here's my question: Is this problem dangerous, or just a nuisance?

If that sound is knocking (early detonation), then it is not particularly dangerous for you driving but could mean an expensive engine repair sometime in the future.

My Ody 2001 EX produces the same grinding sound because of the same cause. I wonder you have found a dealer to solve your problem? If not, pls try AutoWest Honda at Fremont Auto Mall. I visited their service department and my Ody 2001 EX is currently waiting for a new part to arrive. The service manager contacted Honda Tech Line and they seem to have a grip of the problem.

What was the problem and what parts did they order?

The transmission or engine produces a grinding sound when gently depress the gas pedal at ~52 mph and 1500 rpm. The noise goes away if fully depress or let off the pedal. There have been extensive discussions in this forum, yahoo odyssey club, and Edmunds TownHall. Two components were mentioned: shift cable and ECU/ECM (Electronic Control Unit/Module). ECM is a microprocessor that controls how the transmission shifts and controls the way the torque converter acts at different Rpm's. It could be that the engine is fighting with the transmission to apply more power when the sound is produced.

Hi James,

Have you had the opportunity to take a test drive with the mechanic? As a former auto dealer employee, I can attest to the fact that it is sometimes very difficult to detect exactly what the customer is complaining about based on a second hand verbal or written description. That is, you tell the service writer and he/she tells the mechanic, either verbally or on a written repair order. You also need to understand that how "you" describe something isn't how "they'd" necessarily describe the same thing. There is definitely a language barrier between mechanics and customers that I'm sure we're all aware of!


Example: I was given a brand new Mercury Marquis. The complaint was a "rattle" in the front passenger seat. I test drove the car for several miles at speeds up to about 65 mph on varying roads around the dealership, including crossing a double set of railroad tracks. Not one rattle did I hear. I finally went and got the customer and had them come with me. While driving down the road, the car was perfectly quiet BTW, I finally had to ask the customer what they were refering to. At that point, the customer simply leaned forward off the seat back and pointed to it. If you looked "really" carefully, you could see the seat back quivering from the motion of the car going down the road. "That" was the "rattle" they wanted fixed!!

Now, I'm not saying that you're problem is a case of being that picky, but it might be helpful if you can give the mechanic a better idea of what you're refering to by taking that test drive with them and pointing it out directly.

Just a thought and Good Luck!

It sounds as if the shift program is not downshifting as it should (at medium throttle) and that the engine is "lugging", thus causing some vibration. The transmission should downshift without "stomping" on the throttle. A new ECM will probably do the trick.
