What you would verify first is that the timing is correct(ie. timing belt jumped a tooth). If timing is ok, the OCV is next and needs to be checked. There is a mesh filter in the OCV that can cause it to stick and mess the timing up. In order to test the OCV operation, you need to pull the two wire connector off and apply battery voltage to the two terminals on the valve. At idle, the car should run poorly and possibly stall out. Then remove power to verify the car returns back to normal. That would verify the valve itself isn't sticking. Here is the oil control valve, responsible for VVT.(pointing to it)
After those tests, clear the code and see if it comes back as the diagnosis goes a bit further and it could simply be a sluggish OCV, which is common, especially with folks who use conventional oil. Reset the code either by scanner or remove the negative battery terminal for 5 minutes. Then allow the car to warm up and drive it around for at least 10 minutes. Then report back your results and if it comes back.
