Long time no see to lots of you. It has been awhile since I have been able to get on here, lots have changed since last visit. Very nice though!
Anyways, my truck (2000 F350) has thrown the P1316 code at me. It did it off and on one day then the next day the SES light came on and stayed on this time. I searched the code and found out is has to do with the IDM, so I purchased one off of eBay (should be here in a couple of days) started doing research on how to replace it and found out that a lot of people have had the same issues and it was the UVC Harness and not the IDM. Well I already have the IDM coming so I will try that first and if thats not it I will start tearing down to the Valve Covers. (Assuming there is one Harness on each side, I haven't found a clear answer on that yet)
Now here is the tricky part, I don't have an ohm meter and I have very little money. So it would actually be cheaper for me to replace both Harnesses (assuming there is two) at $36.03 a piece (quoted from Int.) also assuming it isn't 100% necessary to change the gaskets ($72/pc), than it would be for me to take it to ford to have them code ($75). Now if I HAVE to change the gaskets can Ford actually tell me witch side is bad? So I hopefully only have to do one side?
I know this is a lot of text but thank you for bearing through it and I hope you can help me make the most economical decision.
The UVC harnesses (one on each side) are prone to come loose, causing the P1316 code that you got. The only thing that particular code means is to retreive the codes stored in the IDM. The Ford dealer can do that for you and tell you which injector circuit(s) are affected. Or you might be able to find a buddy with a PSD capable scan tool. Many shops have them and may charge less to do the test for you. It takes only 10 minutes or so to do, assuming you have the correct scan tool. The other option is to rent a multimeter (or buy a cheap one). What you are looking for is continuity thru the injector circuits on the valve cover gasket outer connector.
Your problem sounds very much like the typical UVC problem. Generally, the only thing you have to replace is the harness itself. Unless the electrical connector pins passing thru the VC gasket are burnt or corroded, the gaskets are reuseable. They have o-ring type seals, and rarely leak.
Hope that helps.
I think you'll just have a spare IDM, as yours is likely still good.
I understand you don't have lots of money to throw around, but as mentioned above, you can get a multi meter pretty cheap (a lot cheaper than buying a bunch of parts you don't need) to see which side is the problem.
There's a good chance that the plug connector inside the valve cover just came loose. If that's the problem you can make a ship to stick in the plug to keep it from coming loose again without replacing the harness.
If you're against spending the money on a meter you could always just pull both valve covers and do a visual inspection to see if the plugs are tight.

Seeing how I do not HAVE to replace the gaskets I will probably just go in and take a look. But if I do find somebody with a code reader what codes am I looking for to show me that it is more than likely the UVCH and which ones represent which side?
Late 01, Ford changed the UVCH connector design to prevent seperation from the gasket. I suggest you purchase 2 harness from Int. ($21 each last time i checked) Each harness will fit either side. (No right/left)
Save your IDM for last. Its probabily just as easy to replace these old harness which are an incident waiting to happen anyway.

What is the Int. part number for the UVCH connectors for my 2000? Just to check with the one that they quoted me (1830844C93)
That's the one you want. If you talk nice to them, they'll sell it to you for $25 or less. Ask for a discount. The worst they can do is say no.
If you get the codes pulled from the IDM, the ones you're looking for are P127X with "X" being the number of the cylinder with the bad circuit (loose harness). The cylinders are odd numbers on the passenger side (1-3-5-7 front to back) and even numbers on the driver's side (2-4-6-8 front to back).
I have been having issues. My truck has been throwing the 1607 code numerously. Now here is the wierd thing. My truck will not start in the morning. If I go start it after lunch, the truck cranks up with no problem. I thought at first that it was because of the higher humidity in the morning. Now I have found that the truck will start after a rain shower in the afternoon. So, the only thing that changes, is the temperature. Would one of my UVC harnesses being loose cause my truck to have these issues also? It is a 2001 F-350. Please help cause I cannot afford to take my truck to the shop.

I can't find a P1607 code, but a P1667 indicates a problem in a circuit between the PCM and IDM. You might check the IDM to see if there's water in it or the connector is corroded.
That was the code. When I looked it up, it said there were problems with comm. between my idm and pcm. Where is the idm located and are there any photos that could help me with this?

The IDM is located behind the F250 emblem on the driver's side fender. Pull the rear of the wheel well liner loose and you'll be looking up at the IDM connector.
The P1667 has to do with the CID (cylinder Identification) circuit, that the PCM uses to tell the IDM which cylinder to fire.

I am on here now because I have every screw/bolt out on my liner and the thing isn't moving an inch for me to see up in there little alone work. Am I missing anything obvious or do I just start yanking away at the liner?
Well it turns out I just started yanking here and there and wha-la there sits the IDM. The new(er) one should be here tomorrow to plug in real quick to see if it fixes the problem, which as of now I am not thinking it will.
Good news is I found a friend of mine that has the scan tool that I need and is letting me use it tomorrow if the new(er) IDM doesn't do the job.

You know, that sounds really familiar
