SOURCE: HOW TO REPLACE CAM SHAFT SENSOR
Chances are your cam sprocket is off one tooth, bring the engine to Top dead center #1 cylinder firing stroke lining up the flywheel timing pointer notch to the timing marked zero. remove the timing belt cover to check that the timing marks line up if not remove tensioner and reset the sprocket so it lines up then reinstall tensioner recheck.

this code is for the theremostat heater control sensor that is under the intake. very labor intensive and should be handle by a quilified tech. the reason the code will not clear is because it is a hard fault and it is seeing it constantly or you do not have the proper scan tool with the correct software. it needs to be vag software and you can get one of these off ebay for under 50 dollars.
you can check the respected fuse for ecm circuit -j220 if that is okay it will need to be tested further.
let me know if you have any more question. good luck

the timing is off, take a good look at the reluctor wheel, make sure its not slipping. other thing is the tensioner, if the marks were all lined up when put together and they are no longer lined up after driving, then the tensioner will have to be replaced.
if you do not have the special tools to set the timing up, send it to the dealer and let them set it up for you, but your timing is off.

- Stretched timing chain
- Failed camshaft actuator or actuator solenoid
The Engine Control Module (ECM) monitors the position of both camshafts and the crankshaft. The ECM performs a test for misalignment between both camshafts on one bank of the engine and the crankshaft. During the test the ECM learns the position of the camshafts and the crankshaft. While the engine is idling, the ECM compares the position of both the camshafts and the crankshaft with the learned value. The ECM will set the P0008 code if both learned values for one bank of the engine are exceeding a calibrated threshold in the same direction.

This diagnostic trouble code (DTC) is generic and applies to all makes & models of vehicles. The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.
The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together.
If the PCM detects that the crank and cam signals are out of time by a specific number of degrees, this DTC will set. Bank 2 is the side of the engine that doesn't contains cylinder #1, the "A" sensor is most likely the intake camshaft side.
Note it is not uncommon on certain models to see this DTC in conjuction with P0008, P0009, P0016, P0017, and P0019. If you have a GM vehicle and have those multiple DTCs, check for service bulletins that may apply to your engine.
