Should I Replace camshaft position sensor???

I posted a while back about my 2003 Jetta 1.8T dying on the highway. Turns out the fuel pump runs so I borrowed a code scanner from AutoZone. I had one trouble code which was "Camshaft position sensor circuit high input. But I don't know if this means the sensor is bad or does it mean the sensor has detected a problem with my camshaft position? Any help is greatly appreciated so I can get back on the road.
Thanks,

High imput? check to see if its plugged in. Its on the passenger side of engine the connector sticks out of the timing belt cover.

If not I would say pull off the timing belt cover, remove the 2 10mm bolts and check the sensor and wheel for damage. If there ok than replace the sensor.
