Hello,
The code P0022 is the intake camshaft timing for bank 2 which is on the driver's side of the engine is more retarded than it should be. I would check the oil first because that could cause an issue as well. It is not a circuit error it is an operational error which is caused by a clogged or malfunctioning camshaft position control valve for bank two. Here is the valve location so you can remove it and check the screen to see if there are metal shavings clogging the oil control ports.
Here is the sensor location and how to replace it for your own knowledge:
