I got code P0672. I checked on the interwebs and found that most other cases of this code are typically paired with other codes. Can anyone lend me some advice as to whether or not I should replace other parts that are probably going to go soon as well. Stranded in winter is not where I want to be.

Thanks in advance,
John

 

Anybody? Help!!

 

Are you having any other symptoms? Did you replace the GP on #2? Only that 1 or all of them? I can understand your desire to be proactive, but I am a believer also in the theory of, "if it ain't broke, don't fix it" sometimes.

 

I have the same thing but on #6.
No other codes.. last I checked.. and only other symptom is lots of white smoke on cold starts.
I have replaced all 8 glow plugs and didn't fix the problem. Went through all of last winter with this issue, thinking I'd get to it in the summer but it's already winter again...

Any ideas would be great. If it's easy enough, I might even do it this winter.

#3 here, but starts fine down to 25° so far
What side is #3 driver or pass?
Guessing we should check uvch connection and ohm gp's?

 

Number 3 would be on the passenger side.

 

Here is a good schematic I saw reading an old thread earlier today.

Thank you both

 

Could this be a failing GPCM?
