I would have a look at the cam sensor as per this TSB as well. It not same codes but it one to check and it costs stuff all to fix just shims.
S-SB-0033-13 : Hard Start, Rough Idle, Camshaft Sensor or Misfire DTCs
Im just guessing here but their is a couple of instances when both cams are targeting opposite to what the ecu is asking for (target angle) seems weird but you probably need to log a good car and check. Wether this indicates problem with sensor or ecu no idea just looks weird
