Good Afternoon, I've been looking around for help and couldn't find quite the right answer. I have a '17 F150 3.5 Eco, I just got PO365 & PO369 codes pop up yesterday (while towing if that matters). My engine now sounds like a diesel engine while accelerating (towing or not), it also sounds not great at idle (but not as bad as acceleration). I read the codes to be "Camshaft Position Sensor B Circuit Bank 1" so I went and grabbed some camshaft position sensors. I know Bank 1 is passenger side but I cannot see them on the passenger side. I see the two on the driver side but cannot for the life of me find the other two (are they even there?).

I also see the Ford 21B10 & 21N03. Is that what I'm actually looking at? Do I need to replace the phasers (and pay for it since I'm above 90k miles)?

Thanks All
