Yea, but, here's the deal with the CPS issue. It does Not cause low power and rarely causes the engine to run poorly. What happens is, as the engine temp causes the CPS to get hot, it just Quits. Like you turned the Key Off. Runs great one second and leaves you stranded the next. After a cool-down period (10-30 mins) starts right up, runs great again and then quits. Sometimes 15mins later, sometimes 15 weeks, ya never know....
That doesn't sound anything like what you're seeing.
Next is the code reader you want to bring. Unless you have a professional scanner, it's not going to tell you much. These trucks are Not, specifically, OBD-II and few generic codes are applicable. Most here use the AutoEnginuity for personal use, if your "mechanic" comes he needs to bring the shops SnapOn, Matco, or the equivalent. A cheaper scanner is useless. PLUS what you really want is a diagnostic tool that will read the Ford proprietary and Diesel Specific codes as well as monitor the sensors and be able to query the IDM with a Buzz Test.
BUT, even that, isn't going to be the same as what you'd get from a dealership. They know these trucks and the common faults in, not only the engine, but the entire drivetrain & suspension. THAT'S what you want so you know what it is your in-for...
