Hi Mtm, Thanks for the reply,i have had my oddy at the dealer today, they have told me to try a valve adjustment, i have also read this on the internet,i agreed to this, it only cost £65.oo ,they had only just finished the test run after the adjustment when i got to the dealership,so the engine was still hot,on driving it home i did notice that it was a hell of a lot smoother,and i dont know if i was convincing myself but it did sound better,Honda told me my valve clearence was a bit tight ...(but yes it was still hot) i took it out for 5 minutes before and i can still hear a tapping but it sounds like a healthy oil covered tap rather than a mettallic rattle,so i am quite pleased at the moment,the dealer also advanced my throttle cable and it now has its original power back from takeoff,so it seems like a good result so far,the test will come in the morning when it is really cold, and damp at 6.00 am i still cannot comment on the fuel consumption as i have only done around 20 miles since i got it back, but yes the valve adjustment does seem to have made a real improvment, i will set the trip to zero once i have filled up tommorrow,this was the last chance for my oddy as i was about to trade it in,i am now going to give it a month and if things start getting noisy again & the fuel consumption doesnt improve ,then i will be getting rid of it, as for the history,and warranty they are non existent as i bought the car as an import,the only history i have is what i have done over the last 2 years,hence the lack off help from the local dealer,although i must say this time they where really helpfull,possibly because i never tried to ask if this was covered under somekind of honda warranty.i am also thinking that the heavy fuel usage is due to my stop n start go here go thier driving aswell,but as mentioned it does run alot smoother so i hope it does improve,,thanks again for the info supplied and happy motoring....best regards Ed

Engine Ping and downshift issues by packerfan5

I will get straight to my problem. I purchased a used 2007 Honda Odyssey with 85000 miles last December from a dealer that had excellent service records. I discovered this engine ping noise after owning it for less than 2 days. Same issue I've seen posted over and over. Some call it droning at 1200-1500 R.P.M. at about 42 miles per hour. The engine will begin pinging at times when the trans seems to be "locked in " while in overdrive. I ended up at the dealer the first time and they replaced the engine mounts - Didn't work!!! I Took it back again and they performed the bulletin on the knock sensor - Didn't work!!! The next trip to the dealer resulted in the replacement of the power steering pump and their inability to find source of ping, although, the technician at least admitted to the noise existing. Finally, I found another post in a different section that referred to a condition called torque shudder. Because my van was in the shop for the 5th time because I didn't want it back until they solved this, I called my service manager and told him about this post. He talked with his technician and agreed that a new transmission was in order!!! Well guess what --- This seems to finally have fixed the problem!!!! The van downshifts smoothly like a dream, it does not drone at 1200 R.P.M.s anymore, and the ping is GONE. I highly suspected a torque converter problem from the beginning but Honda was not admitting to anything. I am very thankful I purchased a 3 year warranty from my credit union for only a $1000.00 because Hondas are so dependable. The total repairs were over $5700.00. The transmission was $4000.00 of it!!! If it was not for these forums I don't think Honda would have my van fixed yet, and who knows how much more it would have cost.

My own odyssey pinging noise.- please help by marekbiela

Hello,
My honda odyssey seems to have a very simular problem.
They, so far, raplaced: some heat shield, tork converter, rear engine mount and knock sensor, but ... I still have the same pinging noise.
Mostly heard on accelaration while going up hill and cruising.
It sounds to me like a valve noise, but ... their first guess was tork converter.
 
Now, after they replaced 4 parts already dealer is saying that noise is ... not that bad ... .
 
Can you give me any tips on how to deal with this Honda Dealer and Honda.
I think I too need a new transmission.
My odyssey has 36,000 miles.
 
Sincerely
Marek

The way my service manager responded to me was by me showing him some of these posts and then him sharing them with the service tech.. I believe they were truly puzzled by this and obviously steer away from the transmission. Honda Inc. never got involved with my case due to the fact I had a service warranty that was very good about putting up with all the parts changes. Ask him to expain to you why they do not believe the noise is caused by torque shudder. I can only say again that the transmission repair has fixed my problem. It has been about a month now and am starting to feel a bit of confidence that my problem with this is over. Hope this helps. - Brian

Another possibility by uns69

I have an 06 exl with 45k miles. I recently noticed what sounded like knocking and pinging and hit the internet to see if others had the same issue. I was surprised to find that so many have this problem and some haven't found a solution. I brought my car in to Honda armed with the info from this forum and odyclub.com. The Honda dealer replaced the knock sensor and it was no surprise that the problem was still there. I brought the car back with a copy of TSB 07-028 (exhaust heatshield). They called me back and said that this heatshield was ok. However they found that the Cat. converter heatshield was not sitting correctly and they adjusted it and "it should be ok now". I figured they couldn't find the problem and just wanted to get the car out of the shop.
I am happy to say that the car is 100% fixed.
So anyone that still has this problem might want to have the dealer check this out.
My symptoms were: What sounded like preignition at 2200- 2500rpms under moderate or heavy acceleration. It got louder over time. If you listen to the sound clip on the TSB for the heatshield, it sounded exactly the same. The noise happend after the car was warmed up and usually right before each shift.
I hope this helps someone here.

Hi i had my 95 ody back to the dealer for a valve adjustment,,this made some improvement,i also filled it with a higher octance unleaded fuel and gave it an oil change ,the noise is still thier but it is about 75% better,it turned out my valve clearances where really tight,i would suggest trying the above as they wont leave you out of pocket to much,,obviously my ody is a lot older but this seems to have done the trick.although if you are under warranty make them do everything possible,including tranny if you are not entirely happy.but definatly get the valves checked,,it makes a big difference. hope this helps.
 
Thanks Ed

Same problems on '09? by cgallery

Purchased an '09 about three weeks ago. Have noticed a slight pinging noise. Using Shell 87 (regular unleaded). Has anyone else experienced the problem on '09 Odysseys? Is it possible that some of the knock sensors are just badly manufactured? I was thinking of taking it to the dealer and having them replace the knock sensor just to see if it would help.

Pinging on 08 seems to be fixed by darthken

Hi all, just wanted to report on my experience. Bought an 08 Odyssey in spring 2008, almost from the start it made a faint pinging sound on acceleration, sometimes louder. Finally had the knock sensor replaced about 3 weeks ago and it seems to have fixed the problem (for good I hope!).

Leased an 09' in august. i hear the pinging noise upon acceleration also. It sounds like the old days when you put cheap or bad gas in your car. Very disturbing to have this problem when im paying a monthly fee on a new car.

Alleged Dealer/Honda TEchline/Service Manager fix?? 07 Odyssey by nasir1997
Oct 14, 2009 (6:03 am)

My 2007 Odyssey only has 27,000 miles(taken good care of)and had everything done so far and Honda dealership has car now(third going on 4th time dealer). Dealer could not fix, so they call Honda Tech line in CA, here is tech line recommendation to Honda dealer:
1. Valve adjustment
2. Software Update
3. Top end engine cleaning
4. Use 93 Octane(to see if removes pinging)
My Local Dealer here is in the south east.
I will pick up car when they have put it back together and ride around with service manager and service tech in car(service tech still hears noise/pinging or knocking).
 
I am upset because a New car should never have a pinging sound. I have tried almost every reputable gas station in my area, but I know that all the gasoline tankers get their gas from the same place all they do is add a different additive or solution before they refill a gas station underground tanks. Also, here in South East I don't think my state has strict policy on Lemon laws. Anybody with answers please respond so I and others can get help to fix problem.
