2015 F-150 Issues
 

Hey guys, so, I have a 2015 F-150 XLT Ecoboost 3.5L. A few months ago I started experiencing issues with it. The truck’s RPMs would slightly raise and it would loose all acceleration. I would also get error messages for Hill Start Assist and Advance Track and wrench icon. When the issue first happened if I turned my truck off and turned it back on the issue would go away, and even disappeared for 5 months. Today however, it is the worse it has been.Looking into it I have found some old forums/threads that indicate a faulty throttle body. However, I wanted to try to reach out to people and see if y’all have any advice/recommendations.

I would run a code scan first and then clean up all your B+ and ground connections before blindly replacing parts..

Update?

Check your brake pedal switch

There is a problem with the throttle body and not too many places are trained or equipped to test and verify it's correct operation.

After two months, I hope he has his problem solved by diagnosing and not condemning an expensive throttle body by guessing on a whim.

Agreed. I just saw a recent post by the OP of this thread, and noticed that this one had no conclusion to it yet ...............

That is frustrating!

I can't tell you exactly what the problem is within the ETC (Electronic Throttle Control), but there is a problem within it.
