Took out the supra and tghis is what happened.

[CampbellsChunkySoupra]

crap. mine was whining like this alot too. could this have anything to do with running incredibly rich?

and can the "turbo death whine" happen suddenly? i shifted from 1st to 2nd pretty hard and it started sounding like it was spooling really hard.

 

[oscolivar1]

code 11 is: Momentary interruption in power supply to ECU

Areas to look are...

Ignition switch circuit
Ignition switch
Main relay circuit
Main relay
ECU
Battery also i guess?!?!:aigo:

Make sure that the ground wires from the engine wiring harness of the intake(underside veiw of it) #5 & #6 are connected. If they are corroded replace them.

Ok but is the car in a fail safe mode? Because It wont hit boost I figure that it was in a certain failsafe as too not provide excessive air or fuel??

 

[ForcedTorque]

Sounds like you are saying "mis diagnosis", because you don't want the diagnosis you got. Check the shaft play..........it takes 5 minutes max

 

[ex3cutiv3]

Im just providing more information (Code 11) before I purchase anything
to better diagnose the problem

 

[TheAmazingDave]

LOL
In the time you've spent tryng to diagnose this, you could have pulled the hose off and found out for sure if your turbo is done or not.

edit: I just picked up a spare CT26 in great condition from eBay for $115 shipped. I'm probably going to send it out to be checked over and upgraded.

 

[lagged]

wow...

first of all check your belts. second check all your IC pipes.

third, reset your ECU drive it around THEN check codes.

Check for exhaust leaks between the manifold and head and manifold and turbo.

The nuts holding the turbo to the manifold became loose on my car and the gasket there blew out.
It got pretty bad in the following days, even with the nuts tightened down, the gasket was gone at the bottom. It was the longest 5 days waiting for that gasket from Champion Toyota... I could make no more than 5psi with a full 3" exhaust
It was bleedingly slow

 

[tlo86]

my car did exactly this, the reason... i forgot to put the IC hose back on the 3000 pipe.

of course i just had a lack of power and it was hard to even get to 40... man people were pissed on the highway hehe

 

[Doward]

Man, what the hell! GO CHECK YOUR SHAFT PLAY. It takes about 60 seconds, and will tell you if your turbo is the problem or not!

You don't purchase ANYTHING! You go pull the accordian hose/AFM/Filter off, and you grab the compressor wheel. Gently move it up and down - does it strike the housing? Gently move it in and out - does it strike the housing? Spin it - does it spin freely for a couple seconds after you let go of it?

 

[SySt]

Just because the turbo is whining badly does not mean it is bad. Maybe you popped off an IC pipe. That would explain the screaming turbo as it is spinning very fast and also makes the turbo FAR more audible with a leak like that. On top of that, you also may get symptoms such as not being able to rev past a certain point. Also, as you stated the turbo does not build pressure. Even a blown turbo will tend to show some pressure.

 

[shaeff]

everyone is pretty much right on in their suggestions here.

death whine (need a new turbo)
squeeky belts (check/replace)
large boost leak (find and correct)

check the IC pipe right off the bottom of the turbo.

[TurboFreak]

Yes please just go out and check the turbo...

 

[89Turbo]

check the IC pipe right off the bottom of the turbo.

-shaeff

the bastard child of clamps.

 

[ex3cutiv3]

I would but I always drive my car hence it being too hot in there so this wkend i will

 

[yrallofthenamestaken]

Dude, go CHECK YOUR SHAFT PLAY LIKE EVERY OTHER PERSON IN THIS THREAD HAS TOLD YOU TO. Jesus...
