I have been hearing a noise an uneven popping noise, from rear, i can hear it when standing by driver door, louder when listening by tire. i have made two appointments with service, and i have been blown off the first time it was not making the noise the second time he said its normal that its the vaporizor or vapor recovery system, that circulates the fumes inside the gastank, that its can make a noise(it wasent as loud as it gets when he heard it) has anybody heard this chattering/ popping sound???

please respond so i can print this page and get my E taken care of, thank you all in advance

I don't hear any pops from my E.

I think I have the EXACT same poping noise. It sounds like a hole in the muffler noise? (but it's not)

You can hear it more when you are in a quieter environment. (ie pull over by a quiet park or in your garage) You will not hear this noise if you're on a busy street.

It seems like the noise is coming from the passenger right hand underside, just in front of the REAR wheel area.

I'm not sure what's causing this noise but I will them to look at it when I have time to bring it in.

Let us know your findings.

the noise you hear, is it a constant noise or does it vary to not at all to obvious when standing by the driver door in a pretty quiet area? i am sure that the reason they told me is wrong because i open the gas cap and dont hear it inside and they say it is a part that circulates the fumes in the gas tank i wonder how bad the problem is and i will be calling them this week

My noise is actually constant. It's almost like I have a hole in the muffler noise (air leak). Like I said, only noticeable in quiet environments.

Your check engine light might come on if you open your gas cap while your car is running since the gas tank is pressurized.

But it seems more and more like a bad muffler (bad internal baffles in the muffler inself) causing this poping noise. This is my guess. It sounds so exhaust related to me. I even crawled under the car while it was running (parked) and listen to where it's coming from and it sounds exhaust related.

If you take your gas cap off while your car is running, problem or not, the check engine light should come on. Honda Tech said so :D

Funny you should ask. These past couple nights have been real quiet as I drove up to park outside the garage and began unloading from the back. It's as if the Chitty Chitty Bang Bang inventor fellow has been at it again, and we'll be airborne any minute now... but seriously, it does sound like a bubble pipe and the bubbles softly popping. I thought it might just be that the muffler was vibrating against something to cause the noise, and that perhaps the hanger bearing was the problem, but I haven't taken a look. It's not particularly bothersome, but definitely not german engineering. :P

I've noticed the same popping noise from the muffler area.

I have the same pop-pop-popping noise coming from my rear vaporizer...But we all know what I'm talking about, right?

Pull my finger.

They ought to warn owners about using too much of that carbonated fuel, don't you think? It can result in emissions from both ends of the vehicle!

I hope I never have to sit in your back seat!

:lol:

:) I just picked up my E today and whenI pulled into the garage I noticed how quiet it was!

The popping noise may indeed be a solenoid valve associated with the vapor canister. I am an automotive engineer with experience at US EPA and Mitsubishi in the area of pollution emissions. All cars have a charcoal vapor canister to "eat up" gas tank vapors that otherwise would evaporate and escape from the car...causing pollution. The charcoal filter works just like a drinking water filter except it cleans air instead of tap water.

My experience is that a popping noise may be normal. It may be louder just after starting. It may be louder in real cold weather. Cold valves may be louder than when they're warmed up. Anyways, it is common for the engine computer to turn the solenoid valve on and off a lot, and do it rapidly, that's why you hear the popping or clicking. More expensive cars reduce the noise by insulating the valve (insular covering)

Thanks for the technical explanation. It's sound right but I want to make sure so I will mention this to my SA next time I'm in.

Actually, if you put your hand to the end of the exchaust pipe and feel for the "puffing", it's actually in sync with the popping nosie.

It's been confirmed by my Honda dealership that this popping noise is normal due to vapor hose connected along side of the fuel tank. Nothing to worry about; the sound is the valve making the poping noise and is emissions related. He even check out a brand new Element on the lot and made sure that the noise was there on another E as well.

I work for a honda dealer, I also own a E. I had the same prob techs told me it was normal. Its not, honda needs to fix this problem. take your E in to the dealer let them know so honda will do something. write letters call
whatever it takes. by the way they're replacing the purge silenoid valve.
but itll go bad again.until the solve this problem.I HATE NOISES!!!!!!
