2015-2017 F150: Throttle Body Replacement
Time: 15-30 min
Costs: $75-320 (aftermarket, reman, or new)
The throttle body on the 2007 and newer F150 is electriconally controlled. The computer utilizes a position sensor on the foot pedal, along with several other inputs, to adjust the amount of incoming air.
With the high demands on the throttle motor, failure is not uncommon. In a running engine, the throttle plate is constantly making micro adjustments in response to vehicle speed, temperature, load, airflow, driver input, and so-on. When it fails, the fail safe is to default to a closed (idle) position.
Common indicators of a bad throttle body (or one on the way out) are no throttle response, a check engine light, and various display messages; See Manual, Service Advance Trac, Hill Start Assist Not Available. Diagnositc codes may include P2107, P2108, P2111, P2112, P2118 and P2119.
Ford knows they had a bad batch of throttle body assemblies. Just about every vehilce in their line for 2015-2016 was extended additional coverage for the throttle body assembly as part of Customer Satisfaction Program 16B32. While the extended coverage allowed for unlimted miles, the program ended Sept 30, 2017.
Doing the repair as a DIY'er is relatively inexpensive and easy. It's a quick removal and replacement. No messy fluids are involved, and no computer programming is necessary. Simple tools can be used.
