Ford Excursion :: Code P0683 - Glow Plug Control Module To PCM Comm Circuit
I have a 2002 7.3L and keep throwing a P0683 code (Glow Plug control module to PCm comm circuit). I have looked though all the Forum posts I could and it looks like the GPR, or the GPCM, or harness are at fault. I know my truck has the GPCM ... does it also have a GPR? I am not getting ANY individual GP failure codes, but the damn thing is having a hell of a time starting in the cold.
1) How do I determine if the GPCM is bad?
2) If I have a bad ground?
3) Bad connector to GPCM connection?
4) If something is wrong with the wiring harness itself
Last night I unplugged the harness from the GPCM, cleaned the connectors, added di-electric grease to improve the connections .. made no difference.
Ford 6.0L Power Stroke Diesel :: 2006 F250 - Code P0677 / #7 Glow Plug Circuit Module
06 6.0 F250 throwing code P0677 #7 glow plug circuit module. I don't think one bad plug would cause a no start, however coupled with too much oil possibly? Swapped my oil about 500 miles ago, I put in 20qts accidentally, drained off about 3-4 qts eyeballed, truck fired up and ran fine no smoke nothing. Yesterday morning I was leaving work and moved my truck from parking space to behind the bay at my fire station, I turned the engine off.
Loaded up my gear and turned the engine to the aux position and someone was talking to me so inlet it sit for a while in the auxiliary position. Went to crank no start, turned the key off then back on and it fired. Fast forward after 7 different starts throughout the day, I'm at dinner with my son we go to leave engine will not start at all, rolls and rolls and rolls nothing. Towed her home and scratching my head. Over filled oil with a bad plug cause no start??
Egr delete, new oil cooler, cat and muffler delete, upgraded Y turbo pipe. Also have an SCII throwing codes p0677 and p0401 egr code....
Ford Excursion :: Service Engine Soon Light Came On - Cylinder 1 Glow Plug Code

View 1 RepliesFord 6.0L Power Stroke Diesel :: CEL On For Multiple Codes - Cylinder 1 / 2 / 7 And 8 Have Glow Plug Circuit Open
Just got back from the beach yesterday. On the way back I noticed the check engine light on and read the codes. It listed 4 codes, P0671,P0672, P0677 and P0678. From what I can find, Cylinder 1, 2, 7 and 8 have the glow plug circuit open. Truck ran fine and didn't miss a beat. Ambient temp was around 80 when we started up the truck so I guess diesel plugs are not to crucial for that temp. I did notice when driving back the Vbatt would jump from 12.2v at1854 RPM (34 MPH) and 13.8v at 1652 (57 MPH).
Would bad batteries or low batteries cause this type of problem? This may be wishful thinking on my part. I have tested the batts with a DMM and they are at 12.3v. I took them out and charged them but they always go down to 12.3v. FMP is 47.5v to 48.5v. It seems suspect that all four glow plugs would be bad so I assume it could be the harness. What are some ways I can test to verify where the problems come from.First thing I would do is get two new batteries as these are still under warranty.

So i just finished putting in new high pressure oil rail cup seals in and a new #2 injector. Truck was running great for about 5 miles and then just shut off. When I had it towed home I plugged in the super chips tuner "no tunes installed" and I have a p0460, p0463, p2290, p2291. I also have a #7 glow plug circuit failure Ive been a little neglectful in getting done.

I'm new to owning a diesel. I have a. 2004 f250 6.0. I gotta smog the truck this weekend but the check engine light is on. Fault is P0674. I've notice during the day it starts up fine but at nights, lately it's been low 40 outside it won't start. Where to start at.
View 3 RepliesFord 6.0L Power Stroke Diesel :: Crank All Day And No Start When Engine Cooled To Ambient Temps - Glow Plug 4 Fault
My 2007 has been having this issue for the last couple of years and has gotten pretty consistent lately. When it's below about 60 and the engine has cooled to ambient temps, it will crank all day and not start. Once ambient temps are about 60, it will fire up and runs like a champ. You'd never know it had an issue. It's got a #4 glow plug fault. Other than that, everything is reading within parameters. FICM, GPCM, or what?
View 5 RepliesFord 6.0L Power Stroke Diesel :: Glow Plug Code And CEL Code P0675
Truck has been running very well while in the warmer North Carolina climate pulling trailers with no limp mode or wrench light. However, when daughter started the truck this morning, SGII showed one DTC and when she pulled it up it was P0675. OK, glow plug num 5 maybe or the module. No issues starting or rough cold idle. I told her to clear the code and we'll see if comes back.
She did ask if it is something she should have it repaired before the trip back to Vermont. So I thought I'd ping the group here since reading posts, they seem to be fairly easy to replace (and assuming it isn't a chafed wire) and I could probably save her some $. Just want to make sure there isn't any chance of real engine damage.
Ford 6.0L Power Stroke Diesel :: Every Glow Plug Code At The Same Time?
Just happened to check codes today for fun and found something interesting. I've known about 2 or 3 glow plug codes since last winter but I looked today and I have a code for every single circuit. Thought that was kind of odd.... I already have 8 brand new plugs and both harnesses from Autonation sitting in the back seat, was just waiting till the fall to change them out. At 176k on the originals I decided to change them all. But now I'm thinking the GPCM may be faulty as well.

Pulled p0678, glow plug 8. I've changed out the glow plug on cylinder 1 a few years ago.
Cylinder 8, being on the driver side rear, is it difficult to change out? Should I just pay Ford or another shop to fix this?

View 8 RepliesFord Escape / Hybrid :: 2004 V6 - Code P0403 EGR Circuit Fault
I'm pulling a P0403 EGR circuit fault on a 2004 v6 Escape.
Last night I changed out the EGR solenoid. Cleared the code and drove around for a while, got on the highway and cruised for a few miles and everything seemed fine. Turn the car off and back on and the code showed up again.
My next step will be to check the electrical connection to the solenoid. I don't do a lot of auto repair.
With my multimeter I will check for 12 volts. But from what I understand I can not check ground as the PCM sends ground to the solenoid to activate it. How should I check the electrical connections to the EGR solenoid?

On a family vacation in our 2013 6.7 pulling a 41ft trailer to the Seattle area from Alberta Canada. Made it to destination yesterday. Woke up this morning started truck and cel on. Bought a code reader at the local napa store and read P206 fault inj 6 open circuit. Any thoughts on driving the truck around with a inj fault? Thought I had read here some where that 6 was the regen cylinder.

I recently picked up a 2005 f250 SD 5.4 4x4... I was having issues with sporadic shifting and wandering shifts while cruising around 100kph, scanned it and came up with p0721 OSS sensor circuit performance fault.
I checked the harness and all looks fine, now I attempted to remove the OSS at the rear of the tranny, got the 8mm bolt out however could not, for the life of me get the sensor out. I tried not to use pliers to twist the sensor or anything for fear of breaking the sensor off and having bits go into the transmission.

How to fix SES P0670?? I understand there's a whole procedure on checking fault.
