Aachen Colloquium, Aachen, 2019Dec 17, 2021 · Technician: Nich M. This fault code indicates that the nox emissions are not being reduced enough by the SCR catalyst. There are many possible causes for this fault code including: Degraded DEF fluid. A faulty SCR catalyst. A plugged or faulty DEF doser. A problem with the DEF pump. An faulty nox sensor.Fig. 1 is a static map of SCR efficiency. In order to achieve maximum de-NOx efficiency (around 0.95) the catalyst requires temperatures over 230 °C. This paper is focused on the first step of this heating process, reducing the time to achieve the proper target temperature when the urea solution is injected into the conversion system.5655 can be a bad SCR, but it's often something else. Knowing the other codes you're seeing would be helpful in pinpointing the issue. Until then: Make sure your DEF isn't crap first. Old DEF that's become diluted is the most common cause of SCR problems. You can check it with a refractometer.SPN-4364 18 Aftertreatment 1 SCR Conversion Efficiency Jan 30, 5:07 PM Jan 30, 5:09 PM Intermittent SPN-3226 2 Aftertreatment 1 Outlet NOx 1 Jan 14, 9:12 AM Jan 30, 6:59 PM Constant SPN-3226 2 Aftertr … read moreIn today’s fast-paced business world, maximizing efficiency is key to staying ahead of the competition.
