Do you have the DDDL software, or a ScanGuage so you can see the temp reading? If the DPF outlet temp is suddenly jumping from normal to crazy high values then it's your wiring harness shorting out. Been there.

And I started getting this same code another time because one of my CAC boots was leaking. If I let off the accelerator while it was doing a regen it would pull in air and the oxygen would cause a heat bloom in the one box. I guessed what the problem was because I had just had my CAC pressure tested.

 

Do you have Scngauge in your truck? Do you monitor boost pressure?

 

Yes. I can monitor boost, but I usually don't.

 

Do you remember what was the max boost value you have seen?

 

I believe it was in the thirties.

 

I was thinking it must be high twenties. DL shows two pressures. Intake pressure and estimated boost pressure. Scangauge reads Estimated Boost pressure value. I have a truck that does not build more than 23psi. Checked everything and can't understand why it does not build more pressure.

 

I will make a point to watch mine tomorrow.

 

thank you.
