Ok, little bit of background. My XD is an ‘03 GT Sedan. The previous owner blew a timing belt and had the engine replaced. I have the paperwork on the engine swap/mileage but it doesn’t say what year the engine is from.

I’m assuming that there were slight differences between the years and there is what looks like a sensor in the front below the valve cover on the right side next to the coolant hose that isn’t plugged into anything. To me it looks like a coolant temp sensor but my temp reads fine and I have no check engine lights for anything.

Here is a picture

Does anybody know?
