Driving around today my cel flashed on. Checked my programmer its saying P0022 intake camshaft position timing-over-retatrded bank 2. Any ideas on the culprit?

 

I'm having the same problem. I have NOT found the culprit, but have read several possible causes. Bank 2 VCT solenoid, oil pump, gunked up engine, or a plug issue. I'm sure there are more, but it is just what I have come across so far.

 

Actually I just solved it yesterday. Mine was from the aftermarket intake I have. Got custom tunes and no more code
