Code 3471 FMI 14

Picture for attention
Hello everyone! Long time reader first time poster. To start I have an 2012 Volvo with the D13, truck has 710k right now and I’ve just got a new code that I can’t figure out. The codes are

SA 0 SPN 3471 FMI 14
Or
MID 128 PPID 328 FMI 14

I am at a lost when trying to figure out what the code means with the FMI 14. I know it has something to do with the Aftertreatment Injection Shutoff Valve and I just replaced it with a new one along with new seals. That did not clear the code, along the way I also removed the 7th Injector and cleaned that out installed new gasket and bolts. That didn’t do anything either so here I am hoping that someone can guide me what to look for next.

Thanks!

 

Did you purchased a new shut off valve? I am not 100% sure if this was the case or not but I was told the new valves that Volvo sells doesn’t work on older model year trucks or at least not mine and I still have a semi new shut off valve sitting in my truck. So my mechanic had an old one laying around and tried it out voila it fixed it and went through regen no issues afterwards. Give that a try, you can find plenty of used valves for less than $50 on the internet but try to find one that’s closer to your model year.

 

Hey, did that fixed your issue? The same code just came back on my truck this morning.
