So the BPV solenoid is unplugged? That might CEL as well.
The soenoid gets constant power when the igition is on. The ECU activates the valve by connecting its -ve terminal to ground.
P1662 is for the charge air control valve!
Codes for the BPV control valve are P1658, 1659 and 1110. It should CEL for an open circuit. WIS suggests checking the wires and connectors.
When de engergized the valve connects the BPV to the manifold. I really do not know what the point of this valve is. WIS does not explain what it does when energized etc.
