P0341 Camshaft Position Sensor Circuit Range/Performance (Bank 1)I am not sure what p164c means.To clarify you have a crank no start condition You have verified that you have Fuel pressureSparkCompression First I would check the valvetronic motor to make sure it is opening the valves you can over ride it by unplugging it and put a small allen socket (3mm I think) in the back of the motor and turn it a couple of rotations 3-4 ( I think it is counter clockwise) one way should be easy the other hard, one way is going with spring pressure and the other going against the spring you want it against spring pressure. WHen you do this is just the socket no rachet. Next if that doesnt do it, You will need to check valve timing to make sure the engine didnt lose time.

Both ways are fairly easy to turn. And where should I be looking to see if the valves are being opened? Is it necessary to remove the valve cover? Or can I just remove the oil cap and look through there ?

And yes cranks but won't start.
Expert:  Kenny replied 7 months ago.
I would try to start the engine after moving the valvetronic motor against the spring this will open the intake valves more.
