So, the way I would go about this is to correct the P1416 code first and then go from there as needed. If you find a wiring issue causing the first code, then it may just fix everything but if it doesn't then you will have to deal with the second problem as needed.
The MDS solenoid is mounted in the top of the block under the intake manifold, so you will have to remove the manifold to inspect the wiring and replace the solenoid.
Also, it is very important to use ONLY 5W-20 oil in this engine otherwise it can affect the MDS solenoid operation.
