CPS problems maybe??

A few times over the last few months the truck hiccups for no apparent reason. Driving along and it acts like you shut it off just for a split second than keeps on going as if nothing happened. It would never throw any codes. This time when it did it I plugged up the code reader and it gave me "Camshaft Position Sensor A Circuit Range/Performance (Bank 1 or Single Sensor)". so I pulled out my spare CPS out of the glove box. (brand new in package never installed before. It is the gray one bought from ford.) After changing the CPS i ran another KOEO test and the same code came up. There are nothing to clear from memory, this comes up when it runs the KOEO diagnostic test. Is there something else I should be looking at? I haven't driven it yet since replacing the CPS so I don't know if it is still having issues.
