Engine nose after shut down?

Just bought a 2015 Tacoma with the V-6 motor. Right after turning the ignition key to the off position, it sounds as though the motor is trying to continue to run. So what's going on? The service tech at my dealer tried to explain it to me but being an "old guy", I just didn't get it the first time around. Whatever....according to him, it's normal.

Yeh, I know..."noise" not "nose", but at least I caught your attention.

 

Try having a supercharger. I was standing outside my truck today and a water pump turned on by itself. Keys were in my pocket.

 

It is completely normal.

 

Yes. Sounds like a diesel for about half second then a diminishing whine. Normal. Couldn't tell you what it is.

 

Heard it is a smog pump we're hearing post engine shutdown. Don't know. Mine does it also.

 

emissions crap checking evap or something combined with your intercooler pump being on same circuit

no shit, the 15's are THAT loud?

 

ok, a real quiet diesel. And not 'loud' but definitely noticeable.

 

ok.......sorry Ive been around and under diesels and I was getting scared by taking u literally lol

 

Yes it's normal, it's your smog pump...and you will soon notice that your truck will make a buzzing noise coming from the rear a few hours after driving it (also normal)

 

I have noticed I have been making a buzzing noise coming from the rear mostly after eating.

 

blowoff valve..................completely normal, unless ur a woman

 

A buzzing noise from the rear? Seriously, what causes the buzz from the rear? Just couldn't help it. I had to ax.

 

on a serious note?

evap check

 

Evap check. That's what I'll blame instead of the dog.

 

Beans lots and lots of beans

 

So it's the smog pump. Thanks.

 

turdsport my tacoma runs the electric water pump at random also. I was curious about that
