First, if it is the Camshaft sensor it's not too expensive and it's pretty easy to replace ...see picture.
Second, I had the same code. Turned out to be the wiring harness from the sensor to the computer. The harness fell from it's mooring (a little 2 cent hook) and let the harness fall into the path of the front passenger-side halfshaft that while spinning burnt through the harness and the wires from the sensor. No wires, no camshaft signal, no go.
