Just dropped off our 2008 Ody for service, including the engine ping/knock issue as discussed on this thread. Our dealer is one of the larger ones located in the SF Bay Area. They knew all about the ping issue and said the problem is widespread with this V6 engine (also used on other Honda models). Initially the dealer was replacing the knock sensors, but soon realized that this was not helping. More importantly, Honda is also well aware of this problem, and apparently Honda Engineering is working on a new knock sensor replacement. The service manager said that the new knock sensor should eliminate the ping problem. His exact words were that we "would receive a letter in the mail" notifying us of the new knock sensor replacement. He did not know when, but it sounds like it may not be too far off. For the sake of our engine's valves, the sooner the better. |

Replying to: xinst (Jul 27, 2008 5:07 am) I don't know about how to answer the association between ping, poor timing and octane. to speak from personal experience, there is a direct relationship between ping, timing and octane as i had found in a carbourated 1984 chrys voyager minivan (the original) that I had. manual adjustment of the timing on that vehicle via the crude distributor adjustment resulted in the vehicle performing better at different octane fuels. ie. adjusted one way resulted in bad ping at acceleration if at low rpm but awesome fuel economy when cruising in 5th gear (yes it was a stick) high octane at this adjustment setting allowed me to have far less ping. note that i don't believe the 72hp 2.2 even had knock sensors in 1984 so that kind of messing around was possible. the odyssey we drive is a very self-aware machine. if there is a ping, the puter will sense it and adjust accordingly. If the pings are pluralized beyond a threshold the puter will log it and hopefully give out a cel to let you know that it had failed in reducing the ping. Given that you got ping and the puter has not immediately gotten rid of the ping (or given you a cel if it failed) it appears that the puter did not even notice the ping. If I were a real smart automotive technician (which i assure you i am not) i would clamp in a scope with logger directly to the line connecting the knock sensors and the engine and see if ther is a signal produced when knock occurs and if so, if the signal is sufficent to trip the computer. most of us here are not experts with this sort of thing nor do we have the vast resources that the manufacturers and dealerships have - we need our vehicles to do our work and haul kids. digging deep into analysis without any of the time tools or training is a stress best avoided. the best we can do is to be informed enought to keep those in the service department from providing the easy half-assed answers we all dread or even worse the denal of the existance of a problem. I was very lucky that I got strait talk right from the beginning with my dealership "roadsport honda" lets hope you and the rest get the same.  --->

Replying to: xinst (Aug 17, 2008 4:52 pm) All of you that are having this problem should do the same. This is total BS what Honda is doing. They should just make it correct even if it means buying this shit van back. Personally because of the entire experience with the way this was handled I will never purchase another HONDA product. They are worthless and do not stand behind the warranty when a problem exisits. Anyone look into a class action? How to start one, etc?

Replying to: a4k (Sep 05, 2008 6:28 pm)  idle. We are having this problem while driving under very little load on the motor. I have had the heat shields replaced once two knock sensors, four idle learning resets with no fix. Honda techline states it is a known problem and now to my surprise Honda has sent me a letter that nothing is wrong with the van and has no non conformities even though the tech line states it is a known problem. I see that the different departments do talk to each other otherwise they would not be sending out conflicting information. What the hell HONDA FIX IT OR BUY IT BACK, that is the new slogan. I started this forum for those who are interested to start another series of posts. http://hondaodysseysucks.lefora.com/forum/category/all/page1/ |
