Engine code 9 - what the hell does this mean?

I got the check engine light on and checked the ecu, its a code 9 .
Online it said a code 9 for an integra was crank angle sensor or circuit. Now under the teg tips it says, Cylinder position sensor. Which one is it, its a 90 GS with a B16a. Also what does this code mean and am I harming anything by driving the car? thanks a ton!

Have you had any starting problems with your car?

Not horibly but it does not sounds right at all when crankin it over? I shouldnt drive it huh?
