Give it a shot, its fast and easy. Make sure to do the ECU reset also. P1606 couldve been anything, but since i did try everything else short of messing with the VVELS themselves, im almost 100% sure that my issue was ground. Hasnt failed since I did the ground wire.
When I started having this problem, it would go away if it sat overnight, then it would come back, and progressively got worse. There might be a faulty pin that loses connection from vibration.
