Black thing under my hood?

I have a 2012 tacoma 4.0 V6, what is the big black thing on the passanger side under the hood? It makes a noise everyday when i start it. Also is there a picture anywhere of the components under the hood? I used to have an 06' tacoma 4.0 and it looked alot different in the engine compartment than my 2012 does, and i'm just curious what all the extra components are for.

 

I think is is the new emission control stuff. It gives you one extra mpg

 

This

But only gives .5 xtra mpg

 

The engine?? Just kidding...does it attach to the inner fender, if so its the cold air intake...it may be vibrating on start up..mine did and it was replaced in warranty

 

Wow. Surprising you guys know where to put the gas.

 

well the manual tells you where to put it duh!.. don't say nothing about no big black thing making noise at start-up...

 

It's a secondary air injection pump for emission control, new to 2012 tacoma.

 

I should've said the round black thing to be more specific and also has a hose coming from it. Sounds like a real sharp whistle, it only last for a second. Also what is the silver cylinder shaped module? I figured it was something to do with all the traction control shit on my truck. Looks like a small motor to me.

 

Does it go beep-boop? Then make a whoot whoot whoot sound? Followed by a fapping noise?

 

that is the Rockwell Retro Encabulator, don't mess with it

 

That would be more of a WHOOP WHOOP. Its all about the WHOOP WHOOP

 

Silver cylindrical thingy is the Canuter Valve, they tend to click as they are failing.

 

Damn.. forgot all about the Whoop Whoop.

 

I think it is a catalytic converter preheater? Or something like that.

 

If it is the circled thing it is emission control stuff

 

Hit it with a hammer until the noise stops

 

Yes that thing in the red circle is what i'm talkin about.
