check engine code P1200-68
 

I have a 2016 Mazda 6 with 63,000 miles. Every so often lately it takes a little longer than usual to crank and once it starts the check engine lite comes on. I have a scan tool and it comes up with P1200-68. which I think was something related to the VVT. I can reset it and the car will run fine for a while. When it did it earlier this year it needed a oil change which seemed to take care of it for about 1800 miles. Now it's doing it again.
Any suggestions?
