Strange Sound When Car is Off
I'm sure you've all heard then the car is off and you're next to it. About every few minutes or so I hear a weird moaning sound coming from it. It almost sounds like a pump or something? I'm sure it's normal but I've asked a few people and they can't figure out what the sound is. I've never heard it come from any other call but this one.

i seem to hear it on a lot on hondas, especially on one of my older cars ('94 accord)
i've always wondered this too

easiest to hear it when your car is sitting in a really quiet area -- like garage or something

Next time you hear it loosen your gas cap quickly .... that equalizes the pressure to the outside atmosphere and the noise stops ....Its definitely coming from fuel vapor venting ..... my TL has been doing it for years though I dont think it has always ... must be something wrong in the EVAP system ?
