This code means something is wrong with the connection between your VTCS solenoid and your PCM. VTCS is used to improve emissions at low rpm's. It basically restricts intake air so that the intake air speed increases and thus creates a greater mixing effect and better combustion.
The P1569 code means that either there is a problem with the wiring between the VTCS solenoid valve and the PCM, or that the VTCS or PCM is bad. Have a mechanic check the wiring between the two components for a short or an open circuit, and then check the solenoid and the PCM if the wiring looks good.
I do not think that driving with this problem would be an issue you might see lower gas mileage, but I do not know how much of an effect the VTCS solenoid has on increasing combustion at low rpms. Worst case scenario, you might get some unburned fuel passing through your engine, which might damage your exhaust system in the long run.
