I had a code for a bad inlet nox sensor. So I got it replaced. Both sensors now I’m getting spn 4364 fmi data valid but below normal operating range-moderately.
After treatment 1scr conversation efficiency. What else can it be? 2015 prostar Cummins isx 450k miles. Thanks in advance!
Hello guys spn4364. Again. And again

Max Milage from Pittsburgh Power 1oz per 25 gallons it's around $140 for a half a gallon but lasts awhile. Had the same code after I started using it, codes gone less regens it cleans the after treatment crap.

Wish I'd known about it 1 month earlier, would have saved me replacing every sensor $1500 and $1550 in labor including both Nox sensors

Check your DEF concentration. I’d also check your DEF dosing valve to make sure it’s not plugged and putting out the correct amount and pattern of DEF and not making deposits of crystallized DEF in your decomp tube.
if that’s all good could have a bad SCR catalyst. -
Oh I fixed it by using the Pittsburgh Power Max Milage No more after treatment codes it makes the exhaust burn hotter through the DPF system and lowers the soot level. I know 100% it works I will recommend it to anyone with a dpf filter.
baha Thanks this. -

That was what cost me 3 grand total replacing all sensors and labor. Code still was there cleared and came back up. Ordered that Max Milage from Pittsburgh Power because a guy told me about it on the CB. $140 for half a gallon mix 1 Oz to 25 gal of diesel. In 600 miles turned truck off started up the next morning check engine light GONE and been GONE ever since

I wish I had known about it when I 1st got my truck I would have been running it from day 1. But live and learn.

I will tell everyone I can about it from now on
