So, I'm not 100% sure that I need to replace the sensor yet, as I don't know if it's actually bad. I read that sometimes this code can be thrown if you plug the block heater in above 0F, which puts the difference between the CAC temp and the fuel temp out of its threshold. Apparently it's supposed to detect that you had the block heater plugged in, but sometimes it doesn't above 0F.
That being said, in case it actually is bad in my case, where is it on the truck, and where can I find the part?
So I did a bunch of digging myself and found where it's located, as there's not really a clear answer out there, unless you dig for awhile like I did. I've attached pictures of where it's located. It's right next to the fuel pressure switch, apparently. Also, the P/N from Ford is BC3Z9F951A.
Code P0181. Where is fuel temp sensor A
