Buzz noise with key on engine off
 

I was reading the codes the other day, so I had the key on but engine off.
A buzzing noise was coming from the Throttle position sensor or whatever is next to it.
The buzzing noise would continue for a while after I turned key off then it would stop.
I can't tell if it buzzes when the engine is running or not.
I circled the two possible things that are buzzing in picture. Blue is Throttle position sensor. Red is ?

Anyone else have this problem ?
I read the thread about the Crank Case Ventilation valve, but this is definately a buzz noise coming from one of these two.

Thanks in advance.

no pic?

buzzing is normal though.... both my ti and my m make noise for 8-10 seconds after i shut it off and on cold start with just key on

Yes, it's normal. It's the idle air control valve.

Thanks!!
 

Thanks for the feedback!
I don't know why the picture doesn't show up.
It shows up when I am logged in.
I have the image in my albums and linked to it, and it is marked public.

Tried again, I am not sure why picture is only showing up when I am logged in.

Yup mine does this as well. I was freaking out when I first heard it too but its normal.

bringing back an old thread......what do you think is going on if the Idle air control valve doenst stop buzzing??

Your DME has got wet and has a green like mold on the back circut board. Take a look at the DME. The drain holes clog and then fill the DME compartment with water, then DME gets wet and is not happy.

nice and straight forward....thanks a lot
