What is the vehicle you are describing ? Sounds like camshaft position sensor to me if everything else runs fine, I have had to change out both on my Ford and GM products, What I have noted in the past and this is not always true, if your powerplant is mechanically fine, then usually it's some sort of sensor.
P0014 Camshaft Position Timing Over Advanced or System Performance
I am getting this code only when I go on very long drives on the highway, usually when driving in hilly areas. The car idles fine and has zero problems running. Even when the CEL comes on due to the code there is no performance difference. I can drive it for months and never get this code. It only happens on very long drives. I have already replaced the CVVT solenoid with a genuine GM one and the oil is fresh and gets changed regularly. Does anyone have any Idea what may be causing the engine to throw this code only under these circumstances?

I would check the camshaft position sensor, if you are taking care of it mechanically and don't feel or hear any unusual sound comimg from the engine I'd start there first, now that the heat season is upon us and the sensors are located on a hot engine they dont last very long they get brittle, if it is an original part chances are the life expectancy is pretty much to an end, after all the sensor is 18 years old, its not so much the miles as it is the age and what type of conditions the vehicle is subject to, like drives in hilly areas, where the vehicle has to work harder with a little more heat output, try that first
