P0299 BY FAULTY TURBOCHARGER BYPASS VALVE/ ECOBOOST F150 & EXPODITION

In this video I discuss how a failed TCBY valve, also known as a turbocharger bypass valve, caused a code P0299 "turbocharger underboost condition" to set in a 2018 Ford F150 equipped with a 2.7L Ecoboost. The valve got stuck in the open position causing turbocharger boost to be bleed off when the vehicle was not supposed to be doing so. This lead to the SES lamp illuminating and a lack of power upon acceleration.
Note: This situation can affect many of the Ford F150s and Expeditions equipped with an Ecoboost engine, 2.7L or 3.5L. And to my knowledge the 3.5L Ecoboost has been being used on the F150 from 2013 to present day, 2022. Also, the 2.7L Ecoboost has been used in later years on the F150 to present day. The Expedition equipped with the 3.5L Ecoboost can also be affected. I believe that the 3.5L Ecoboost has been in use of the Expedition from around 2015 to present day, 2022. The turbo systems on all of these vehicles are very similar and almost the same. However, there are some differences. So, as always verify everything.

When u pull the valve does it leak oil? Do I need a pan? I’m probably about to have the answer

I have an underboost code showing for my 2016 2.7 and when it gets to higher speeds the orange wrench light appears and I lose my turbo completely. If I pull over turn the truck off the turbo works again. I brought it to the dealership i was looking at a $7000 turbo job but the turbos and waste gates tested fine. Long story short they put a wastegate silinoid in and it ran better than ever almost like a new truck for a week and it happened again. I’m gonna bring it back but it’s seems electrical and very difficult to track down. Anyone have this issue

Did you ever find out what it was?

@azteca466 mine was bad cat converter. Was blocked so no pressure code was showing for turbo.. I bypassed cat for now and had no problems no engine code or lights etc.
