RE: SPN 4364 FMI 18? (05-12-2017 )JMBT Wrote: Jimeneztrans84, also check the simple stuff. Mine has thrown this code often since new. It can be, and I would say is often, set by poor quality DEF fluid. If you have no other codes. I would first check for leaks, use the DEF pressurizing test on insite, then get under and look for leaks. Then replace the DEF pump filter if it has been in longer then 50K. Then unplug both NOX sensors and reseat them with a little di-electric grease. Then clear the code. If it comes back, which mine never has after the above, then pull and inspect the decomposition tube for deposits, and look into replacing the nox sensor or sensors. That's the only code I get here and there. I will reset the code and it comes back 1 or 2 weeks later always when I'm climbing steep grade... no power loss, I replaced the def filter about 50k or so, might change it out again...start with the cheapest parts. I replaced the inlet nox sensor about 75k miles ago. I need to inspect the def injector and scr can... will be changing out filter tmrw.... | |||
