How to manually operate throttle under the hood?

I'm trying to identify a whistle noise that seems to be coming from under the hood and I want to work the throttle manually. Is there a way to do this from under the hood? I've searched the forums but can't find the answer. Thanks for any help! It's a 2014 with 2.7 engine.

 

To my knowledge, you can't.
2nd gens has a "drive by wire" system. Pedal is connected to a sensor that goes to the ECU then that goes to the throttle position sensor, thus giving you gas.

Tried my best to explain it, oh well.

 

Dont think you can not many cars/truck/vans/things have manual throttle body. I recommend having having a friend press the throttle and you try to locate it under the hood. That is the best I can do to help sorry to not be more help

 

You can't. It's wires to the throttle body not a cable.

 

Only way to control the throttle is with a scanner..

 

you attach to the data port in the engine bay with a techstream and run it that way

 

That's what I was afraid of, and I don't have a Techstream. Looks like I need to recruit a helper! Thanks everyone for your input.
