Keywords DPF: Diesel Particulate Filter Bake: Process of cleaning soot out of DPF Soot Level: How much soot is calculated by the engine ECU or controllers Benefits of cleaning your DPF filters Better MPG Better Throttle Response Less frequent Regenerations (Passive) Longer DPF Life Less Downtime The DPF filter is a part of the emission system that helps trap the soot collected from your exhaust stream. The soot that is caused by the diesel engine is gathered from various sources. In order to meet emission standards, the DPF / SCR / EGR / VGT system was developed to reduce NOx Emissions. How do you know that your DPF system needs to be cleaned? Regenerations that are occurring more frequently is an indicator...
The number one cause of a 5 MPH derate in a Volvo truck is the SCR/DEF system not operating properly. The SCR/DEF system was implemented in Volvo Trucks 2011+ to curb exhaust emissions on Class 8 trucks. If you have a Paccar engine and are stuck in 5 MPH derate check out this blog post. What is a derate? A derate means that the program inside the engine computer limits either the power or vehicle speed. A derate is designed to protect you from causing engine or DPF damage. A derate can be caused by various sensors or system. However, when it’s a specific 5 MPH derate then you can be certain that the problem is related to the emissions,...
SA 16 DTC Explained = OBD / P-Codes Heavy-duty truck fault codes do share similar results with the OBD automotive standard, but the heavy-duty manufacturers do things a little differently. This is why we recommend using good sources for your information so you have the right information to fix your truck. Which trucks use OBD Fault codes? Volvo Trucks 2014+ Mack trucks 2014+ Prevost Bus 2014+ Here is look at some fault code data that you may have seen on your dashboard. The following information is on a 2015 Volvo VNL 670 with a Volvo 500hp D13 engine with I-shift. Fault #1: SA 16 DTC P113000 [SA] stands for Source Address. In this particular example, the “16” stands for the engine. So this fault code is coming from...
What does ‘SCR NOx conversion efficiency low’ mean on Detroit Diesel DD13, DD15, DD16? Fault codes associated with Selective Catalyst Reduction (SCR) NOx efficiency low are the most dreaded codes you will find on the Detroit diesel application and can drive your costs high. Long story short, these fault codes mean that the efficiency in the aftertreatment system, aka the 1-Box, is not operating within the required threshold (70%). This measurement happens between your inlet and outlet NOx sensors and it’s called your SCR NOx efficiency. If the SCR NOx efficiency goes below 70%, then these fault codes get set “Active.” The only way you can clear these codes is by doing a forced regen with the SCR NOx efficiency above...
Owner-operator - IG TransCraft Express LLC Ilya has been driving across the United States with his dog, “Diesel.” When Illya first used the reset tool he said he had to wait until a check engine light appeared to see if it’s an actual problem with the truck or if it’s a Ghost code. Ilya was left shocked when he plugged it in and it actually cleared the codes. Ilya wanted a tool to keep him on the road without any added downtime due to fault codes coming from the Engine & Aftertreatment system. Ilya is now in control of his system and will continue to use the reset tool when something comes up. Ilya is a proactive owner-operator who takes the...
