Here's the thing,,, the CPS was recalled and replaced under a campaign that was started Many years ago. So, the chances that yours is the original one is kinda sketchy...
Here's how you can tell, the original ones were made of Black Plastic, the replacement Ford used was Grey. If you were looking from the front of your truck, towards the motor, it's located at around 10 o'clock behind the crankshaft balancer.
BIG CONTROVERSY on CPS's and what's the best one to use (do Not use anything that's not from Ford or International, none of that aftermarket crap...) but it's all about the colors
Black/Grey/Blue,,, whatever, I think you just want a good spare to try and the Grey is the cheapest and easiest to find (If yours is Black, and bad, you might even be IN for a Free one installed at the dealership - take a look at it
Here's how to find & change -> Welcome to guzzle's CPS R&R Web Page<
Here's some of the basics on the differences, and why you might want to hang-on to a Black one (if it's not the problem) -> Black, Grey, & Dark Blue Cam Position Sensor Perdels Test - Diesel Forum - TheDieselStop.com
But again, I know your current priority is to solve the problem.
