Do the codes remain even if the SES light goes out? I do know someone with a machine to test but I was trying to avoid spending anymore money than I had to.
Yes, the codes will remain in the computer until you clear them out, even if the SES light is no longer illuminated. If you leave your batteries disconnected, it might clear them out. I think it used to on older vehicles, but not sure about the newer ones. Anyway, I'd want them to stay until I could find out what they were for.
Didn't see that you were new. Welcome to the forum!!
As an FYI, to post a new thread, go to the main page for the 99-03 7.3L PSD page, link here: https://www.ford-trucks.com/forums/f...splay.php?f=31
Once there, you should see at the top of all the threads a blue button on the left of the page that says "new topic" that you can click. This link may take yout there too: https://www.ford-trucks.com/forums/n...newthread&f=31
It will open a page where you type in a title, which shows up on the list of threads, then just type in your post, like you are replaying to a thread, and hit submit. Pretty simple, once you post a couple, you'll get the hang of it.
Thank you very much for all of your help! I had the codes read and that is the problem!!! Now wish me luck getting home and replacing it tonight! Your site helped me very much as did all of your responses!
By the way...still gotta love the Ford Trucks! Best truck I have had and this is my first real issue I have had with it! Other than those darn door locks! Lisa
Glad we could help. Replacement should be pretty smooth. 10mm socket and 20 minutes or so. There should be some guidelines on replacing it here on the forum if you haven't read through them already and would like to.

20 minutes is just about as accurate as you can get. I put the new CPS in my PSD today. The 10mm bolt was one tight little sucker, but it finally gave up. I was surprised that the old CPS came out as easy as it did. Just pulled and wiggled it back and forth, and it popped right out. The new one went in very easy, and the 10mm bolt got a nice coat of anti-sieze.
Thats pretty good Neil, I actually had a bad experience with mine about a year ago. The idiot that had the truck before me rounded the bolt just enough so that I had to buy a Craftsman damaged bolt extractor socket and remove the fan shroud so I could fit in there to pound it on with a hammer. The so called 10 min. fix was like 2.5 hours once I got done. Not to mention all the bloody knuckles. Anyways, the new cps has antiseize and a new bolt now so no worries when I change it to the new blue cps. Everytime someone says how easy it was to change I laugh at my bad luck!!!

Bet u had a few choice words for that guy!

Slightly off the main topic title, but still mentioed in the thread. What can I say I'm just catching with this chain.
I've only used di-electric grease back in my 'Gas Engine' days for spark plug boots. When saying to use it on the connector - is that on the connections directly or only on the sealing surface?
If on the contacts will/can it short across them? Will it reduce the power thru put???
Good morning all! Truck is running great (so far). It took about 20 minutes or so to change out the CPS. To the gentleman looking for the Blue CPS...I am in the Portland OR area and I am sure you can order the part from Brattain Int'l and it is $115.00. Have a great day!

better to find out in your drive wat than beside the road. one more advantage of the blue cps , better than a spare ford cps in your glove box. glad you gt her figured out.

Directly on the metal contacts is the main point. I ususally try to get some in the "fins" of the sealing surface of the plug too, just to help out a little. There is a clip that holds the plug in, so it's not going to slip out.

Dielectric grease will not cause the contacts to short out. That's one of the things the grease is designed to stop -- other contaminants from getting in the plug and shorting them out. It will not reduce power through the port either.
Just an update. Did my first full tank run of all around driving, with the IH blue CPS. Looks as though I picked up 1.4 mpg. Same fuel station filled to the top of the neck. Plus the truck seems to be running smoother and quieter the more miles I put on.
I've got an update also. Unfortunately, I have done too many things to the truck since the last fill to have any idea if the CPS has helped or hurt. What makes matters worse is I just finished the harpoon and hutch mods. I just filled up and I know I got more in with the harpoon mod than I used to! Oh well, other than mileage, of which I dont have a clue, she fires up quicker and runs smoother that with the original CPS.
