Hi all. My 22 F150 Limited with the Powerboost and 36000 miles on it recently threw a engine code P237F. As best as I can determine it related to the manifold pressure sensors (three of them). I decided to clean all three and the dirtiest one was the one on the top rear of the intake manifold. I then reset the engine code and a few hundred miles later there has been NO engine light.

Just a bit of FYI.


PS sensor cleaning videos for the engine are on youtube

 

Correction i am wrong. The light came back. It turns out to be the exhaust heat exchange valve

 

Lets see 2022, Warranty?

 

Yes indeed warranty.
