Same here. 2024 Powerboost, 4000 miles. Got the check engine light on last Friday driving in Vermont. OBD link MX+ says P144B code, Ford Pass says Vapor Line Restricted/Blocked. The truck is at a ford dealer now. Technician says there is a TSB and he is going through it.
check out this driving POV:
If I am not mistaken, around 12:57, you can clearly hear the starter sound.
At a few other occasions, for example, around 11:34 and 11:48 the ICE kicks back in without such a sound.
Still puzzled how the logic behind starting the ICE works.
May I ask where to find the Factory Service Manual? I see Helm and Factory-Manuals both offer a service manual? Also, Ford Service Info has this 72hr subscription for $26.34.
First time Powerboost owner here. Have been driving my 2024 Powerboost for a month now. I understand that the BISG has been removed from the 2024MY, thanks for the excellent analyses and posts of @UGADawg96 @fatBatman @Snakebitten @testerdahl among others...
