#105 of 154 Whining noise while accelerating
Jan 01, 2011 (10:06 pm)
I have a 2003 Honda Pilot. When accelerating a whining noise can be heard. When you let off the throttle the noise goes away so the noise is only heard under a load. I have made sure it is not a bad ground connection on the radio and I have also checked for diconnected vacuum lines and have found none. Not sure what to check next? Have not had the "D" light flash, the check engine light come on or any transmission slippage. Any help would be appreciated.

I finally took in my 03 Pilot for 90K svc at which time dealer replaced VTM-4 fluid. As of now, about 1 week since, no snorting noise. They also replaced the transmission fluid but prior to the svc I mentioned this snorting/puffing of air and they (Honda dealer in Mem) claimed they had not rec'd a similar complaint -- but thought that it was possible that the replacing the rear differential fluid could resolve. Don't know any more than that but I'll advise the group if the snorting noise returns...but for now...so far so good. TN Pilot

Thanks. Will change fluids, soon.
#109 of 154 03' Engine Mounts / Snorting , FYI
Aug 24, 2011 (9:17 pm)
My mechanic was trying to diagnose the snorting issue and discovered the Front and R Front engine mounts were failing. During replacement, He noticed the engine had shifted toward the drivers side. Parts Desk told me the life of these mounts is about 80k. (mine 77k). Ironically, the snorting isn't as loud, but it still there when changing gears, 35-45mph. Will replace Trans fluid next.
But my advice to all is check your engine mounts. He said the torque was lifting my motor over 3".

i created an account on here because of this blog. I have an 03 pilot with 151k on it and i love it, ive had all of the talked about problems and a whole lot more but i have the keys to the local mechanics shop so i go there after hours and tinker with my pilot. im in college so i dont have the cash to be paying diagnostic test being run on my vehicle everytime something comes up. i have the shuttering problem...happens when the vehicle is trying to decide to come out of overdrive back down a gear...its like its confusing itself and not sending the right fluid pressure to let it shift properly or maintain overdrive. (this is a torque converter problem). my mother had an 04 with 118k on it and my buddy worked at honda and told me that it was a torque converter and not the entire transmission....i also have the tac needle movement and havent diagnosed it. i have a hunch that it is electrical. a surge in power by the alternator can cause this...or so im told by my home town mech. i havent heard any puffs of air or anything like that, just the normal slight sound of the engine going from 1400 rmps to 1600...other than that nothing. so far my vehicle has had all routine maintainance done by the book bc ive only owned it about 10 months....but i was a mech in the navy so im gonna try from here. other things to look out for noise wise is almost a bed spring sort of noise when coming off of an uneven surface. this is just a spring shifting usually happens when the last tire is joining the other three on the even surface. only happens at very slow speeds usually under 5 mph. i will keep you posted on these problems and let you know if i figure them out. right now im experiencing very loud rumbling on the road. my tires could be just really worn but it almost sounds like wheel barings. i changed all 4 three months ago so id like to think its not. im gonna drain and change the differential fluid and see what that does....

Well, 101.5K miles I had my '03 Pilot in for her new timing belt, water pump, and tensioner at the end of Sep. Per these threads, I also asked them to check the engine mounts. The engine mounts were all fine and I didn't detect any snorting noise/tach movement for the first few weeks. But now for the last few weeks I'll still hear an occasional snort ~ 45-48 MPH. Doesn't happen quite as often or as loud as in prior 6 mos but still there. Not sure what to do...will replace plugs, etc. at the next oil change but have already changed out transmission fluid, rear differential fluid, and now the timing belt, etc. but still there yet less noticeable. Will continue to monitor but still no firm resolution thus far...
#112 of 154 2011 EXL 4wd noise from front
Jan 03, 2012 (9:38 am)
I have about 5,000 miles on my Pilot and when I hit about 50 mph and increase speed or hit 50 mph and take my foot off the gas and let car decelerate I haer an moanining type of sound from the fron of the car, seems to come from the tires. Does this sound like a problem with the bearings?
Has anyone else had this issue?

omg! its the idle valve EAC control unit. common problem on odysseys and pilots. causes fantom revvings and intake gusts at random occasions and rpms.

I'm not familiar with EAC control unit...is it an expensive part and labor to replace? What happens if you ignore it - will it get worse damage anything else? This is the 1st I've heard a potential root cause on this issue...and how did you learn this? Thx for any insights you can share with us Pilot owners...
