| 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. | |

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

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 |

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.

| 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!). | |

My 2007 Odyssey 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. |
