I have a 2015 3.5L EcoBoost with 126xxx that I purchased early this spring. This week my "Check Engine" lamp came on, so I scanned it and it showed the P0327 code for the knock sensor fault. I've had a hard time finding much information on this error within F150s so I figured I'd reach out here to see if anyone else has ran into this.
My understanding is that I either:
1) Must locate the wiring harness for the knock sensor and inspect for damage. However, I can't seem to find a diagram that shows the location of this.
2) Remove the intake manifold in order to access and replace the knock sensors themselves. Also having trouble finding guidance on what is needed to complete this repair.
Again, I'm fairly new to the 3.5L EcoBoost so I'm still a novice with the motor. If anyone has any suggestions it would be greatly appreciated!
The KS is a real pain in the you-know-what. You have to remove the intake manifold to get to them. If the problem is in the wiring, maybe you'll get lucky and it is before the harness disappears under the intake.

That is the jist I am getting. Thank you so much for providing those graphics!
I'm hopeful that the wiring harness is the answer, but I have a suspicion that I'll be pulling that intake manifold off this week.
Having a hard time finding information on removal of the fuel rail - anyone have any information on this? It is possible to remove the fuel rails while leaving the fuel injectors in the cylinders?
