I have been fighting an engine light for a few weeks and have replaced many parts. I am getting an engine light with code p0018 for crankshaft position - camshaft position correlation (bank 2 sensor A). I have currently replaced the bank 2 camshaft position sensor, bank 2 variable valve timing solenoid, spark plugs, oil filter with OEM part and valve cover/intake gaskets. I replaced the valve cover and intake gaskets due to a valve cover leak I found while investigating this issue. The van runs better that it has in a long time at this point actually. But the fault light returned every time. The only thing I notice while the vehicle is running is a slight hesitation on acceleration and a brief shutter or rough idle while sitting still. I do not want to just keep throwing parts at this thing without a specific direction. Any advice would be great! Thanks!

Yep, I have seen this problem before it is the camshaft actuators that are bad not holding oil therefore not holding their position causing the code. I have seen low engine oil levels cause this as well so oil full? I sure it is so no worries. You might as well do the chains as well.

Here are the diagrams below to help you get the job done, start by disconnecting the battery and draining the coolant. Do an oil change once you are done.

You will need to remove the harmonic balancer. Here is a video on how to do that part and the diagrams below to show you how to do the rest you can get the parts from Ebay or Rockauto:

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
