Where is the engine location of the crankshaft position sensor on a 2016 Ford Taurus SE 3.5L?

It would be highly, highly unusual for the crankshaft position sensor to be faulty. What was your troubleshooting process?

Most likely it would do about as much good if you just threw it in the glove box and left it there.. Perhaps if we had a few more details about the actual problem we could offer some beneficial assistance. Good luck!
