crankshaft/camshaft position correlation error. Can be caused by slipped timing belt or either sensor manfunction. First thing to do is check connectors on both sensors. If good, then you should check the valve timing by inspecting the camshaft sprocket alignment with timing marks. If you need instructions, please let us know.
SOURCE: i have a check engine
Honstly im not fromilar with porche engines but i have seen these two codes together along with P1345. The problem has to do with the correlation of the signals from the cam and crank sensors. Once again i don't know what this set up has or dosn't have but if it has a distubtor shaft check for exess movement in the shaft with the cap off if you can turn the rotor from side to side to far then the signal from the cam and crank gets distorted . If you have coil packs im not sure how to test it but the problem is still the same a signal distortion Hope this is of some help i usely don't answer questions that im not sure of but iv'e seen this before and its a tough one to track down
SOURCE: CEL P0016 and P0017, Changed
if you have a lot of miles on this car , it might be time to change the timing belt or at least tighten it up if it still looks good. Stretched belts can also pop these codes as the cam and crank are no longer lined up exactly where they should be to each other.
SOURCE: P0016 and P0017 check engine pop up after i run for 10 to 15 miles?
the common causes for code P0017 are as follows:

DTC P0016: Crankshaft Position (CKP) - Intake Camshaft Position (CMP) Correlation Bank 1
DTC P0017: Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation Bank 1
A camshaft actuator stuck in the full actuation position may cause the engine to crank but not start.
The camshaft position (CMP) actuator system is an electro-hydraulic operated device used for a variety of engine performance and operational enhancements. These enhancements include lower emission output through exhaust gas dilution of the intake charge in the combustion chamber, a broader engine torque range, and improved fuel economy. The CMP actuator system accomplishes this by changing the angle or timing of the camshaft relative to the crankshaft position. The CMP actuator simply allows earlier or later intake and exhaust valve opening during the four stroke engine cycle. The CMP actuator cannot vary the duration of valve opening, or the valve lift.
During engine OFF, engine idling conditions, and engine shutdown, the camshaft actuator is held in the park position. Internal to the CMP actuator assembly is a return spring and a locking pin. During non-phasing modes of the camshaft, the return spring rotates the camshaft back to the park position, and the locking pin retains the CMP actuator sprocket to the camshaft. The park position for the CMP actuator and camshaft is 8.5 degrees before top dead center (BTDC), which is equal to 17 crankshaft degrees BTDC. The engine control module (ECM) can only command the CMP actuator to retard the valve timing from the park position, or advance the valve timing back to the park position. The total range of valve timing authority is approximately 20 degrees of camshaft rotation, which is equal to 40 degrees of crankshaft rotation.
Problems with this will cause the PCM to disable traction control and Stabilitrac .How many miles on your vehicle ?

I think your sensors are pattern parts and the readings /resistances are not the same as the original parts ,try some bosch units is my first suggestion ,
