weird sound when engine at around 2000 rpms

[soup1207]

Hi,

I got my new yaris 2009 about a week. I found there's some cracking sound when the rpm is at about 2000. It happens even if I use N shift. It seems like there isn't any cracking sound above 2000 or below 2000 rpms....The sound is like kekekekekke

Does anyone know the reason for it?

Please....><

[soup1207]

the sound is actually like dadadadadadadadada
it happens around 2000 rpms....
Is it normal?Why?
Thanks....

[Tamago]

it's the hamsters..

[PhilD424]

lmao its the Vtech kicking in

[TheSilkySmooth]

This sounds more like Duh... duh ... duh...DUH!

[TheSilkySmooth]

lmao its the Vtech kicking in We dont have VTECH and it doesnt Kick in. We have vvti and its constantly variable hydraulic cam phasing ala BMW vanos.

[soup1207]

TheSilkySmooth and PhilD424,

Do you mean it's normal?
Even my 14 years old 95 previa doesn't have that sound...
I am so afraid and want to have it fix if it's abnormal
I only have the car in my hand for less than a week....

[PhilD424]

We dont have VTECH and it doesnt Kick in. We have vvti and its constantly variable hydraulic cam phasing ala BMW vanos.Still doesn't make the car quick lol. And I'm well aware that it doesn't have that crap Vtech.

[soup1207]

Today I asked my friend out to see the problem.....
However, the weird duh duh duh sound disappear when I see him....(I drive a while to meet him in somewhere, which is less than 5 minutes driving)
After I home and turn off the engine for a few hours and turn it on again, the duh duh duh sound come back. It actually happen between 1900 to 2000 rpm...It never disappears even I drive it about ten minutes.
Is there anyone know what happen to my yaris?

[TheRealEnth]

You gotta check your bov brah'

[Lafiro]

There was a thread on this a while back. Around 1800-2000rpm, the engine/car shake and you can even hear it.

There is no response from toyota as to what causes this.

I have noticed that in 2nd gear, around 1800-2000rpm, my car is loud, and the engine sounds very bad.

As soon as I give it more gas, and it gets above 2000rpm, or changes gears, the noise is gone, and it sounds/feels smooth again.

I really don't know whats causing this.

I have 50,000miles on the car so far. This coming week I am going to change my motor oil(royal purple with 6000miles on it), and transmission fluid. I am going to also replace the spark plugs, and maybe even the cables if need be. At the end I will also be replacing the drum shoes, and the shocks.

Honestly I say all that but at the same time have $0 to do it all. *sighs*

Obviously no one knows what it is. It's kind of hard to figure out from that description. Maybe if you can get some video of it or something someone can figure it out. You should take it to the dealer, since it's a 2009, it's still under warranty.

[soup1207]

Thank you everyone...thank you
I will take it to the dealer....
Actually do I have to pay for a check up because of it?
It seems so non sense if they charge me as I only got my car for a week only

[CtrlAltDefeat]

I seriously doubt it... but don't take my word for absolute, because I don't know for sure...

[CDavis7M]

Check your oil level. The valves could be noisy if the engine is cold, especially if you have run low on oil before.

[soup1207]

Lafiro,

When did you start to have this duh duh duh sounding problem to your Yaris? My car has only 400 miles on it in total.....

[soup1207]

my car is just a week, every tank is full as I checked it today....

[highwaypass]

once,it happened to me too.Each time i put my transmission to neutral,it goes same as yours.
Mine was 1.5 hb M/T. When i check it to my dealer,they say that they just do some lubrication to the gearbox.I dunno what parts,but it works well with mine.

[soup1207]

I see....thanks,
I start to realize that it happen at the beginning I start the engine. After I speed up several time, the weird vibrating sound disappear. It happens again when I turn off the engine for about half an hour to 45 mins.
I just talked to my dealer today and they suggest me to leave my car for them overnight....
so they can let the car cool down and check it.
I am going to do it on Saturday.

[highwaypass]

Good luck then,and welcome to yaris! :w00t:

[TheSilkySmooth]

Still doesn't make the car quick lol. And I'm well aware that it doesn't have that crap Vtech. My cars is quick, whats wrong with yours? You gotta use good oil (motul or total), good fiilter (purolator, wix - not toyota) and good gas (shell) and leave the radio/cd off. There is an electrical interference problem with the stock radio wiring. If you have a 5-spd 3 dr you should get to 60 in the 7-to-8 second range with ONE shift. If you got a 4 door auto you are doomed:tongue:

Honestly I say all that but at the same time have $0 to do it all. *sighs* The stock oil filters are defective - use a wix 51396 or a Purolator. The RP oil doesnt work well in this car. Just run Mobil clean 5000 or 7500 or Penzoil Platinum 5w-30. if you have the bucks run Motul 8100 . You use the wrong stuff the vvti oiling gets messed up and the car runs bad. I Cannot overemphasize how important it is NOT to use the black toyota denso filters for tthe car to run correctly.

And I cannot overemphasize how wrong you are about Toyota filters. They are more then fine, Granpa, or whatever your other user id is/was. I've used the black Toyota filters for the last 62,000 miles and all my UOA are excellent, regardless of the brand of oil.

[The little red pill]

Sounds like a good idea to just have it checked out. Since it's not a maintenance item, any work should be covered under warranty. Even if not, they are legally bound to provide you with a written estimate before any work is done.

[Lafiro]

My car has had that vibration every since I bought it.

As for the bad sound some of the time, under 2000k rpm, especially if there is strain on the engine I just found out, like going up a hill; this has only been an issue of rmaybe the last month or two at the most. Same time I know I have to change the oil.


So what is this that I should not use royal purple, nor use the stock air filter in the box?

Wow, what should I use then because I plan on buying the oil today or monday at the latest.

[soup1207]

I got my car back from dealer and they can't even hear the vibration.....
the noise seems got disappear in a shorter time than before although they still happens.

Lafiro, do you mean that every time you hear that noise you would go to have oil change?

[IllusionX]

Actually.. i heard some vibrations when accelerating from 2krpm or below. I heard it most when i have the rear seat flipped down.

probably just the muffler rocking around..

[soup1207]

The dealer said they can't hear any sound and put my case on record. They ask me check again when the first time oil change has come.

Would they charge me if they finally find out the problem at the time I have my first time oil change? The problem started to happen at the first week I got the car.

Lafiro, do you mean that every time you hear that noise you would go to have oil change?

No, It does that all the time.
Its hard to explain because my car has a few problems.


******First off, from 1400-1800RPM, especially taking off, and on a slight hill, my engine sounds like the valves aren't getting enough oil and sounds like they are stuggling bad. After a little more gas, and higher RPM, it goes away.

******Another problem is that in nuetral, the car vibrates at about 1800RPM.

Another problem, usually only after the car is used, is that when I come to a ******stop, the car is sqeaking a lot.
This I can replicate by driving the car, stopping, and opening my windows, or even just my door, or better yet, sitting next to a brick wall, like a garage or a drive thru. Its very annoying, and I cant figure out whats causing the noise. It goes away though after the car sits for a bit, or I take it out of D/R.

[Kaotic Lazagna]

I have that same weird metallic sound coming from the engine bay as well. Mine started after I hit a concrete block on the freeway at 60 mph. It doesn't appear when I'm in neutral, only appears when I'm driving around 2k and 4k rpm. Nothing was damaged other than my front bumper and some plastic panels under the front bumper, so I have no clue what it is.

.........I have 50,000miles on the car so far. This coming week I am going to change my motor oil(royal purple with 6000miles on it), and transmission fluid. I am going to also replace the spark plugs, and maybe even the cables if need be. At the end I will also be replacing the drum shoes, and the shocks........ Well, you can save what you were going to spend on spark plug cables - your Yaris doesn't use 'em. Must be nice to have a lot of money - the brake parts and shocks shouldn't need to be touched on a car with this mileage.

[AlexNet0]

There is an electrical interference problem with the stock radio wiring

wtf are you talking about?

[soup1207]

Here is my situation. If you got any clue after seeing it, please let me know. I also sent it to my dealer as they said they don't hear any noise for the last road test....><

[mikenacarato]

for the record everyone... its NOT VTECH....that is a childs toy brand... its VTEC.

you car is brand new...take it to the dealer and get them to take car of it.
also...why does everything silkysmooth say seem to NOT make the slightest amount of logical sense?......

[mikenacarato]

everything in this statement is incorrect..the black oem filters are 100% fine and will perform just as good as the next alternative...heck i use a cummins fleetguard filter in my car..... ive used royal purple in my car in both engine and transmission and i will continue to use it because it works just fine.

im pretty sure my car doesnt hit 60 mph in 1st gear...... and why would there be an electrical interference with a stock car...i think toyota knows a little about putting a car together.

I think he means after one shift, the shift from 1st to 2nd. at the top of 2nd your hit 60mph (I hit about 63-64 because of my underdrive pulley)

not sure what the electrical comment is about... the drain might cause and teeny tiny imperceptible drain on hp but other then that...

[Lafiro]

Its not that I have money???? My shocks are 100% dead.

My brakes aplly more in front then back. After taking apart the drums, the shoes are faded/cracking.(and yes I adjusted them to the point where my ebrake is nice and stiff at 1 click!)

My oil is at 6500miles. It HAS to be changed.

My tranny/engine are at 51,000miles, I think they both deserve oil change/new spark plugs.

hmmmm what else.... lol
