well i guess im gonna have to get my hands on a multimeter and see what the post reads when in the on position. anything else i should look at or test while i have this meter?
after reading more i think that if its not the idea of the gpr getting 39 amps, theni must have a gp out or connector thats gone bad because it states that
For California only, the glow plug system monitor will start when the glow plugs are commanded on for over 30 seconds and the battery voltage is between 11.5-14 volts. A glow plug code will be stored in continuous memory if one or more glow plugs are not being powered.
im gonna do some tests with a multimeter and ill let u knwo what i come up with
The manual list 3 separate parts to that shunt.
4 -- Left Bank Glow Plug Feed Post (Part of 1825931)
5 — Left Bank Sensor Feed to PCM (Part of 1825931)
7 — Right Bank Sensor Feed to PCM (Part of 1825931)
8 — Right Bank Glow Plug Feed Post (Part of 1825931)
9 1825932 Shunt
Well, two things. I think Alan is right. I was thinking 99, and 00 has no GPR. Now the codes you are looking up is for a GPCM 00 model, at least from what I can see. May apply to the 99 but don't see how since it is wired differently but could be. That shunt simply connected the left and right to the same GPR post from what I can see. Shouldn't matter wiring directly from what I can tell. Since you have those codes, I wonder if there isn't something wired downrange that we don't know about detecting that fault but I cannot see how since they are wired together at the GPR, shunt or no.
Maybe smokin was onto something with her evaluation of the 109???

On California vehicles the glow plug monitor system is part of the On-Board Diagnostics II (OBD II) System.
The glow plug monitor (GPM) system is designed to find failed glow plugs or failed wiring in the glow plug system.
The GPM system uses a low resistance shunt to conduct current to the left and right bank glow plugs.
Three sensing wires measure the voltage drops across the shunt when the glow plugs are operating. A failure in the glow plug system will set a diagnostic trouble code (DTC).
well i think thats it, looks like i have to go back to the original style gpr, if the ses light is still on then i must have a failed gp or wire lose or pinched right?
Gotcha Alan. Makes sense now. Kinda like my post about testing the GPR between both large terminals. A good test of the meter or light. I am curious as to how they are wired to detect that fault independently from left to right since there is a common mounting point, shunt or no, on the GPR.

Stand by, been at this one and others for a while, I can't remember all of you symptoms. Any other problems but the SES?
Edit: OK, after a quick review, I would say that it may be a sneaky wiring issue. Did you have any codes before the new GPR? Why did you replace it? Maybe I didn't go back far enough.

I got stuck in the PCED pinpoint area in the KC test section. There is a diagram there showing all except Cal GPCM models. Shows a GPR and could apply to Dangle's rig. Of course this was under a Y2k model because that is what I was looking up but he has a 99.

Thats where I started but the workshop manual goes into the GPR(Glow Plug Relay) with GPM (Glow Plug Monitor) that the 99's had before the GPCM came out in mid 00.
Hey John,
My ses light came on and the truck started running rough right away. I pulled over and plugged in my superchips tuner and it pulled a P1316 code. I tried clearing the code and restart...but it came right back. I also noticed that when I got into the upper RPM's, especially 2nd and 3rd; the ses light would go out and the truck would start running good until the upshifted.
I gotta admit though...I did go by a buddies shop and have him scan it so I knew which cylinder was misfiring. I wanted to make sure the IDM wasn't toasted...Found the # 8 injector not working. Pulled the VC and just went ahed and replaced the harness and it ran great..code cleared and put it back together.
I'm still really new to diesel technology...hope it helps!
Thanks for the reply. Mine was running rough when cold and never really smooth and quiet all other times. We'll see how the harnesseshelp. I plan to install them tonight if the rain holds off.
I also found a good mechanic that has some PSD training and knowledge along with all of the tools to check it out. So, if this doesn't help it's going over to him to get scanned....
This is my first post to this site and I must give a HUGE thank you to everyone in this thread!
I own a 2001 F350 and just the other day I experienced the same problems as listed here in this thread - SES, code P1316, rough idle, lack of power. I was very concerned about my truck and I refuse to go to the stealership unless I've exhausted ALL my options! The posts in this thread saved me hundreds of dollars, that I'm sure of! Yesterday I picked up a set of the plastic connector repair parts and dug into the drivers side valve cover. Guess what I found....yes the injector wire harness was almost completely unplugged! I installed the plastic clip, put it all back together and now it runs perfect for the low price of $14. I would like to ask if you guys think I should install one in the passengers side just to be safe, what do you think?
Again, thank you to everyone posting here and I look forward to using these threads more often in the future, what a super experience you guys are great!
P.S. I've had a few small problems with this truck over the years and I have also found that International carries everything I've ever needed for about 60 - 80% less than Ford!
