Are there any other codes in the system besides camshaft sensor?This will not prevent the engine from turning over, so there is something else going on here.What work has been done to this car recently?
take the oil cap off while someone is inside the car. look at the cam shaft and have someone try to start it. does the camshaft move?
If no parts can be see moving, and it sounds like its spinning really fast, that means you have a timing chain that has came apart, generally b.c. of a timing chain tensioner. The timing chain keeps the camshafts and crankshaft all in sync, so when you start the car the crankshaft is spinning but not the cam shafts, the engine computer sees that difference and sets the code.
The only way to determine the root cause of this failure and what exactly happened is to remove the engine, and remove the front cover to see whats going on. I attached a diagram of what it SHOULD look like and also as a visual to my explanation as to what happened. I really hate to be the one to tell you that bad news that its not a simple fix.
