Hi,
Did you try turning the engine using a breaker bar or just the starter?
If you used a breaker bar and can't turn it, you will need to tear the engine down to determine the cause. I can't be sure, but here is what I suspect happened.
Since you have a code related to the camshaft position sensor, I have a feeling the timing chain for the cams jumped time. The problem is this. This engine is known as an interference engine. Basically, if the engine timing between the cams (valves) and the pistons is off, they can hit each other because there isn't enough room. If that happens, most times there is interference between the two causing internal engine damage.
If I am correct, that would explain why you can't turn the engine with a breaker bar. Also, the cylinder head would need to be removed to see what actually happened. In most cases (not all), it is less expensive to find a good used engine.
I attached a pic below showing the cam gears and the timing chains. There are two on this vehicle. The larger one is where I feel the problem is.
If you want, I attached the directions below (extensive) for replacing the timing chain. These directions will give you access to check things. You don't have to do everything, but enough to remove the timing chain cover and inspect.
The biggest problem is this. You can't turn the engine to see if the timing marks are off. But at least, you will be able to see if there is damage to the chain or timing chain gears.
Let me know what you find. Also, if you do take it in, could you let me know what is found? I'm really interested in knowing if I am correct.
Take care,
Joe
