Replying to: pcullen (Sep 17, 2008 10:36 am) My 2007 EX-L knocks like crazy on a hill. Our neighbors turned around to look a few days ago. Embarrassing. Higher octane gas makes a little difference but the engine still knocks. I have an appt for next week. I also have the steering knock. I have brought it in before and they professed not to have heard it. I will insist this time. |

Replying to: pcullen (Sep 22, 2008 4:26 pm) I ran it through the normal things that set it off, and I only heard it a little tiny bit. Not nearly as much as it was before. I am not going to complain just yet. I want to run it for at least a few days and see what it does. I am keeping my fingers crossed!

After reading these posts, I will not buy a new' 08 Oddysey which I was seriously considering. Or any other Honda using this engine, which includes Ridgeline and Pilot. This is total BS. Engine pinging (detonation) is a serious issue and it will eventually lead to serious engine damage. I cannot believe that Honda has these problems with their new vehicles.. My '99 Mazda 626 V6 with 208k miles never pinged, and I can run any octane of fuel - the knock sensor will just retard the ignition timing with lower octane to prevent pinging. BTW, engine pinging can also result from a failed EGR valves, if it fails closed. This was a common problem on pre-knock sensor vehicles. With a properly functioning knock sensor, the timing would be retarded, so no pinging. The reason why a vehicle would ping with a failed closed EGR valve was that the EGR valve dilutes the fuel-air mixture and the base ignition timing is slightly advanced to compensate. When the EGR is no longer functioning, the timing is too far advanced for the mixture and pinging occurs. Of course, this is only in vehicles not equipped with a knock sensor. |

Hi everyone, I took my car to my dealership. They replaced the the knock sensor after I told them the TSB issued by American Honda, which someone posted on this forum earlier. The service soon manager searched Honda Canada's database found a TSB that he said was just like the American Honda one, but with a different number. Regardless, they changed it, and my engine is totally ping free. Ran it on 87 octane. I drove up slope, pressing gas, stop and go traffic -- all those road conditions which caused pinging before. No more ping! The engine also FEELS more powerful and sounds quiet overall. So, it seems, based on my experience that the new knock sensor they put in now SHOULD NOT be defective. Good luck, and go get those dealerships!
