So I've got a 2016 F150 with 2.7l Ecoboost. What I need help with is in the picture below. Long story short, I had a rat chew the wires to my Engine Coolant Temperature (ECT) sensor. I'll detail more below but I do not recommend tackling that yourself! While putting everything back, I somehow lost or misplaced a sensor/relay. If any of you could snap a picture or post the part number I would be most grateful!! I can't figure out what sensor/relay this is or where the hell I put it. You'll have to take the Ecoboost plastic cover off of the top of the engine but it is just 2-10mm nuts.
Long story about the ECT sensor and the rat from hell....
I had a bag of cattle cubes I left in the back of my truck for a couple days in July. A rat decided to chew into the bag and then start making my engine compartment home. While doing that he proceeded to chew a bunch of wires in the matter of 24ish hrs. I was out in my other truck for work on a Thursday and came home that afternoon to jump in F150 to run to town and all kinds of lights were on and truck barely cranked. Immediately it said "engine coolant temp high". I was able to drive it around to my shop where I started investigating. I found 3 wires chewed up along the front cross member. Then I found 4 more hidden behind the battery tray. I fixed all of those but none of the symptoms went away. After much digging I decided it had to be the ECT under the intake. That ended up being the biggest pain in the ass the remove! Below all of the intake manifold, the fuel rails, the coolant hose, down deep in the valley of the engine lies the ECT. About halfway into it, I watched a YouTube video of a guy and he just stopped part of the way through and said, "don't do it, just don't do it, take it to Ford and let them do it, it ain't worth dying over". He was most definitely correct. Pain. In. The. Ass. Attached is the new harness compared to the old one.
