Is the electronic throttle body part of the powertrain? on 2007 Ford Freestyle

I was told the electronic throttle body was not covered under the powertrain warranty.

Asked by for the 2007 Ford Freestyle
The electronic throttle body most likely is not part of the powertrain warranty, but may be covered under the emissions warranty. Have a dealership run the part number, vin # and mileage under the tab "parts coverage" web page in the OASIS website.

No powertrain is engine, transmission or transaxle and front and rear axle if it comes with one ( Power and Drive Train ) Get a independent shop to diagnose and give you a estimate for repair and you can locate one here
