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?

Where did you get the sensor? Unless it is an International (or re boxed by Ford) you're going to have issues.

They won't. You'll need to run by the dealer or get one online. Search for CPS and woodnthings8 on the forum. He did a comparison between the dark blue cps meant for the 94-97 PSD and the original black and replacement grey. I'd get the dark blue as it seems to work the best of the available models.

Standard brand cps are terrible quality.

Like rt said oem only. Ford or dieselorings sells them

check the pigtail as well for water and or poor connections, insulation, etc.

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.
