I could rev the engine and the -29 would over shoot to +39 and settle back around 0. I thought this was the issue that was throwing the code. To me it looked like clogged OCV passage/filter. I got an engine flush and oil change. Data logging since then does not show the -29 anymore but I am still throwing P0018. Both intake cams seem to respond well and lag slightly behind the target angles. I assume this is normal since electricity is faster than oil. I have swapped OCV's from side to side and cam position sensors from side to side. Still get P0018 (not the other side).
Any idea what is going on guys? I am out of ideas.
Could it be the Crank position sensor. I assume I would have more problems if that were the case. It seems to drive fine once i reset the DTC's but then I get the code and it become "detuned" (slight limp mode).
Please help!!!

take a look at the TSB s in the sticky at top of this thread, that cam code is likely covered under warantee on 2013 and prior cars if still covered its a known problem
unfortunalty might be related to the cam sensor the oil control valve,the cam sproket actuator or even the ecu itself, the TSB shows how to diagnose but its quite complex and could possibly require multiple parts to be replaced
p0018 is cam position correlation error, ie difference between what ecu asks for and what the sensor feedback reads.
