I've never worked on this system, so I don't want to be the person who says it's okay to drive it, but this system is actually just a means of adjusting the "personality" of the engine for varying conditions. We used to do this during the engine building process to tailor the engine to the application. For example, an old Chrysler 440 c.I. Could be built for lots of low-end torque to get a huge motor home going from a stop sign. The same engine could be built to make a highway patrol car have the same low-end power as with a tiny V-8 engine, but scream to life above 60 mph. Those differences in power ranges were done by altering the camshaft timing.
Your system does the same thing, but instead of being set for one condition, it adjusts your engine's power band to match the speed the engine is running at. You get the best of both worlds.
Depending on the failure, you are either losing that feature, or you are losing the reporting of the results of that feature as it's making the adjustments. To say that a different way, the feature may not be working, or it my be working but the computer isn't being told it's working. The fault code only indicates the circuit or system that needs further diagnosis. If the system is not working, what you should notice is lower-than-normal power when accelerating from a low speed, or reduced power at highway speed, or possibly both. To my knowledge, normal driving should not cause a problem.
