I have a small rubber hose dangling beneath the front of the my 2000 Odyssey that is not connected to anything at the bottom. At the top, between the two fans on the radiator, it is attached to what looks like a servo. What is this, and should the hose be connected to anything at the bottom, where it is now dangling free?

I think this has to do with the front motor mount.

Im pretty sure that has nothing to do with a motor mount. Possibly a EGR valve?

You have an active motor mount up front (nod to @rbhollabaugh )

That tube at the bottom should plug into it somewhere, if it comes from the little electronic control valve. I'll take a look at my 2002 EX tomorrow and see what I can see, and give you the lowdown on what I find (maybe some cellphone pics, too).

Thanks Odyfamily. I’ll be replacing the splash shield in a few days and I want to take the opportunity to make sure all is connected as it should be.

This pic is like yours, looking downward. Note the little hose is clipped to the front of the vehicle, and there's a little plastic thingie that joins it and another hose that leads to the motor mount (top right of photo).

This next photo is taken from under the car. You can see where the hose sits in yet another clip, this one attached to the bracket which that engine mount attaches to. The hose disappears in my pic, but best I can tell, that hose actually loops around to the right of the pic (hidden) and attaches to a hose nib on the engine mount.

For orientation, you can see the two radiator fan shrouds at the bottom of the above pic.

Next pic: note where it plugs in at the bottom of the mount (tiny hose nib near the center of the mount's bottom)

Thank you OF. That’s exactly what I was looking for. Appreciate your help!

Im confused. The OP took a photo of a sensor. Not a motor mount. Also motor mounts rarely go bad on these cars.

@Odd Essay , the OP posted a pic of that little electrically controlled valve that provides a vacuum path, as required for the active motor mount. It's part of the EMC (engine mount control) system. This part is common to all three Odysseys we've owned (2001 EX, 2002 EX, and 2003 EX).

It's rare that the front active mount on a Gen 2 Ody goes bad, but it's happened. We've had the occasional post where someone describes some "brown goo" that isn't motor oil, all in a puddle directly under that mount, like a molasses spill. That's a failed mount. Again, rare.

@MikeR-PDX 's question was about the hose that disconnected itself from the mount. His mount was fine, but he was searching for the point where it connects to the active front mount. It is not obvious at all where this hose nib is, hence the images I provided.

Waiiiit.... Youre saying that valve has something to do with our motor mount?! Why does a motor mount need a sensor on a 2002 car? Also why does a motor mount need a "vacuum path"?! Motor mounts are not controlled by sensors. Im confused.

 

[0dyfamily]

Where did anybody say it's a sensor? Well, I guess you did. It's a valve, electrically controlled, that's all. Servo is a good word for it (by the OP). That active mount helps with NVH (noise, vibration and harshness). That active mount can be firm or not-so-firm, depending on when that valve is actuated by the PCM.

No need to over-think it. Some people who endure a failed mount just do this: they install a much-lower-cost aftermarket non-EMC mount, put a plug in the vacuum line, and press on with life. Our OP just wanted to find out where the terminal end of that vacuum hose connects to.

Now, go have a beer and think about important stuff, like the latest NCAA brackets.
