I wish it had BDT. I installed my billet way after the noise had started. It did it when i bought it.. i bought it with 65k and now i have about 96k on it. I am removing my billet grille this week though and Plasti-dippin my factory TRD grille. Maybe that will do it.

 

I cant be the only person on earth with this Stupid high pitch noise! Come on TT World! Help-me out!!

 

My intake whistles at different rpm's maybe that's it.

 

Well i have a K/N air intake and i hear that from outside the hood.. but this is certainly under my dash... in the cab...

 

That's your answer

 

it is certainly your intake. Mash the gas and your whistle will go away. Slight throttle application and an associated whistle is well documented here. Something about removing some screen on another thread seemed to help. There is no throttle linked item within your dash that can whistle, unless its ground loop issues with a speaker.

Anybody else know where i might be able to find this post/Forum? I will look in this. It did it with my OEM Intake and it still does it with my K&N intake system?? SO it very well could be that.

How do i fix it?

 

Under the passenger side dash is the fan and cabin filter.
You may have some debris (a leaf for example) that got sucked in there and is creating a whistling noise as air rushes past it.
Drop the glove box to access the filter.

 

Thanks Ponyuk.. I will look into that.. I know i have changed my air filter twice but i have never throughly looked for debris. i have pulled a leave out before though.

 

Just did my k&n filter and charcoal filter delete and now I have the whistle, it's definately intake

 

Mine is stock and dose it.

 

It does it stock or not. It doesnt matter either way. An aftermarket open element filter will be louder of course but anyone paying close attention can hear it with any stock tundra. The volume of air happens to be moving into the intake tube at such a rate to cause the whistle. Its normal and no cause for concern.

 

Sound like a dog whistle high pitched.
I don't mind it if it is air, but really noticed it after flushing trans which got me thinking.
Now 15,000 miles later after flush and trans shifts fine but the whistle still there between 2000-2300 rpm only when accelerating. I can rev that motor in park in that rpm range and not heat it. Above 2500- redline no whistle just beast of a motor is all that is heard!

 

It's the intake trust us.

 

That's when I'm hearing it too... exact same sound.. it sucks man!

 

I trust you Ryan.. just hate that there is absolutely nothing to be done about it... there has to be something ... No to thread jack... but... I am sure it is for the 2012 model only but what is the info button mod?

 

It's the buttons for avg mpg, instant mpg, and miles till empty.

 

Next time you hear the whistle, turn the cabin recirculate switch on and see if it goes away. If it doesnt you can pretty well eliminate the cabin air filter as the culprit. Good luck.

 

Read in TS about a metal round steel strainer like thing I think after the Mass air flow sensor that if taken out this whistle goes away. But for me if it is only air I will leave it alone. Don' want to open any can of worms.

 

Dynamat/fatmat/second skin (sound deadner) the firewall. Problem fixed.

 

I hate it too.....but not so much I would get rid of the CAI.

No fix I know of.

EVOL ARDNUT

you are a LIFE SAVER> I am doing this mod soon! I will let everyone know if it works for me. I have a K&N AI on mine and my truck has whined since i first got it...

 

I think it sounds like a turbo starting to wind up

 

It works!!!!
NO MORE WHISTLE!!!
I can enjoy my ride once again!!

 

Did the screen removal. Cut down the whine at least 85%. It was very distinct and loud before but I barely notice it now. I think the reason it still remains a little is because of my K&N intake and i left the 1/4" tabs on the gasket. I tried to Dre mel them off and they got to hot and started melting the gasket so I just reinstalled .. Thank you so much for the link post and the original write up

brother just use tin snips. those tabs will come out in less than 30 seconds. I
have no whistle whatsoever thank God!! it was driving me crazy!!!

 

I didn't have any here at the house last week when i did it. Couldn't drive anywhere with my intake and throttle body disassembled. It was about a 10 minute mod. I think I might just bring some tin snips home from work and get it done tomorrow evening.

Did you cut all the tabs all the flush to the gasket? I know the bottom tab holds it in place along with the top rubber tab.

i trimmed all of them back as close as i could. tin snips made the clean up a snap.
had no issues fitting the gasket back into place and all worked like a charm.
just be careful torquing those throttle body bolts back into that cheap ass intake chamber. Im amazed at how toyota skimped on some of the parts on this truck compared to previous models....

 

Alright jaymz I am going to get this handled tomorrow night and I will follow up and let everyone know how it turns. My pain just might be someone's gain. They will know to trim them all the way back the first time lol.

should be a cakewalk
i think im the king of having to do things AT LEAST two or three times when it comes to this kind of stuff btw. you arent alone my friend.

 

I gotten them back nearly all the way this is good as it gets guys. Let's hope the whistle is completely gone

I tell ALL in the truck that hear it that it is MY TURBO SPOOLING and to hang on!

I S**t a brick when I started to hear it after flushing trans 2 years ago.
I thought it to be weird only at that 2100-2400 rpm range in drive and does not matter the gear. IN PARK never when revving it at same rpm !

AND I HAVE STOCK AIR BOX.

AFTER MARKET INTAKES WILL WHISTLE in park and revving them up.

Sound is not bad, but what bugged me was where it might have been coming from.

.

incorrect with the TRD CAI
does not whistle in park revving at any rpm.
only under load.

the metal screen causes the whistle
simple as that.
