Hard start and codes after replacing CPS

My EX began having problems while away on vacation 2 weeks ago. Threw codes for the Cam position sensor and would smoke like crazy before cutting out. When unplugging and checking the CPS I noticed water in the connector which wasn't a major surprise as the week required some water crossings.

So replaced the sensor as the truck continued to have issues and throw codes on the drive home. I was only able to get a hold of the Grey Standard sensor. Since replacing the sensor I have had an intermittent miss while cruising and a hard start issue which seems like dead batteries so I pulled cleaned and re tightened all battery connections, pulled and checked the starter and connections and load tested the batteries. I am also showing 2 persistent codes a P1670 and P0603 which I have never seen before. Any thought or ideas? Related to the CPS? bad sensor?

I got it from the local parts store its a by Standard, ill take it back and see if they carry the ford one.
The new Ford CPS seemed to fix some of the issues, I put it in checked the pig tail and pins and fired it up. The truck chugged for about 2 minutes but settled out and has been running good ever since. It did throw another set of codes again and I haven't driven the truck yet to see if they will clear out or not.

I am still having the hard start issue and I am beginning to think its starter related.
