Try searching that code P0022. This is a common issue on cars with the M272 engines, not that we know what kind of car you have since you haven't updated that part of your profile.

P0022 "A" Camshaft Position - Timing Over-Retarded (Bank 2) so you must have a V6 & likely a quadcam V6 which is the 272. A camshaft position sensor has likely failed. See Johnand's thread in this regard. He found cheaper CPS's that are OE from suppliers other than stealers. Replacement is easy.

Happened to me a month ago P0015 what is same thing but on Bank 1. They first change camshaft sensor but didn't help. Second time they did some kind of camshaft timing udjustment as they told me and that helped. I have no idea how much would that cost because it was under warnty.

First replace the camshaft sensor. It is DIY and costs about $135. If this does not work then it's a dealer job with once only use impulse wheels etc.
