Hey,

I had a code come up on my SGII this morning. No cell light. P0677 - cylinder 7 Glow Plug Circuit fault. Anyone have an idea of rough cost? Truck feels like its lost some power.

I have also had some codes come of on the EGR flow, and one other one that have gone away after clearing them and not returned. Want to do the EGR delete, I see a few SCT tuners on the web. Which one should I go with if the only purpose to buying it is for the delete?

If you are going to delete the EGR just leave the valve in place and leave it plugged in, you dont need the sct it wont throw a code cause it wont know the difference as long as the egr opens and closes when comanded to do so by the computer, if you want to take everytjhing out, than you need the sct so you dont keep throwing egr codes. Change no 7 glow plug, but when one goes so too will the others, replace them all as were getting closer to winter every day now.

 

Any Idea on cost to replace all glow plugs?

On the XPD site they say the SCT is needed for 06-07's to avoid the code? What is the trick to avoid that?

Thanks,

 

if you leave the EGR valve hooked up to the wire, it will not throw the code and the fan will run correctly. If you remove the EGR valve, you will get a code and the SCT can turn it off. The SCT runs in the $400 range.

 

What are the pro's and con's of leaving the valve hooked up to the wire V.S. pulling it all and using the scanner?

 

if you leave the valve hooked up, you don't need a $400 scanner to turn it off and your fan will run correctly. You can delete the EGR cooler and just let the valve lay there, working as before. No added cost.

OR

Remove the EGR and the valve and pay $400 for the scanner to turn off the CEL.

 

that is the pro and conns

 

So I am just throwing money away bying the scanner? Sorry if I keep asking the same question. I just don't see why someone would pay for a scanner unless they wanted it for performance?

 

The behavior of the truck with the EGR delete depends on the flash version in the PCM. Early trucks generally dont throw a code and later models generally do. I forget the code number but it's for reduced EGR flow and is measured by a lack of expected temp rise at the iat2 sensor and something else, maybe MAF.

I don't think a scanner model can keep the CEL off, you need a tuner that can tell the PCM to ignore the readings.

 

I'm sure a scanner of lesser quality could also turn the CEL off well. Having one would allow it to be turned off whenever it popped up.

The SCT does come with canned tunes.

 

IMO only change #7 glow plug. Lots of times you get a single failure and others last for a good long time.

 

The reduced EGR Flow is P0401 I think. I got that one last month and it went away and didn't come back, then last week I had a different code which also went away and hasn't come back.

Thanks Bismic, I Will just change the #7, I found a new Diesel Mechanic in the area who works at the local Ford dealership and does this work on the side, The guy I was refred by said he does great work, and he get start on it tonight. I think I will have him do something as far as an EGR delete while he has it. I had my PCM re flashed in 12' when the dealership was screwing me over on my FICM
