high pitched noise (like mosqito sound) from engine
 

Anyone's Z making high pitch noise (like mosquito sound) when you accelerate? Its coming from engine.. My Z is 2012 and barely past 15,000 mile... will be taking it to dealer but wanted to know if anyone else had same problem.

I think it's the ECU whine

Thats what thought after research but noticed its different after watching video of a Z having ECU whine problem. This sound suddenly started so I dont think its normal though..

It could also be the diff or power steering pump. Lots of whining in the car. I just pretend its a supercharger.

If the whine is coming from the passenger footwell area, it's probably the ECM. If it's coming from the engine compartment, it could be a lot of things (injectors, PS pump, ...).

Allegedly, there is also a throttle body whine.

Sigh.... I just bought this Z 3 months ago and it's already causing problem.. 2012 Z just past 15,000 miles.. it was CPO....

****..

I never believe the CPO **** with the stealership!
Imagine they even made you pay extra for that!
Hopefully they will fix it!

Could be mosquitoes...

IIRC wasn't the ECU whine issue corrected for or during the 2010 model year?

OP, are you new to manual transmissions, or manual transmissions in sports cars? Could just be typical gear whine.

I have a 2010 and mine whines all the time....

oh, that's the turbo....nevermind:wtf2:

On a more serious note OP there are a lot of noises specific to the VQ platform going on under that hood. I would not automatically assume there is something seriously wrong with it. It is runs, acts normal and they don't find anything you might just be alright.

Funny when I bought mine I heard a whine after shutting engine down from the engine bay area. It only occured once so far.

Probably the fuel pump.

So many mosquitoes in FL that's all I hear outdoors....Live music and age prevent me from hearing that noise, haha.

Nope, i'm not new to manual transmission and my friends who drives manual as well thinks there is something wrong with this noise. They couldn't figure out what exactly is causing the noise
