When you manage a fleet of heavy-duty trucks or long-haulers, your repair technicians need to be aware of several different engine components and functions, including derated diesel particulate filters (DPFs). If you omit or skip the valve adjustment when it is the recommended time, it can adversely affect engine performance and create the conditions to prevent heat recovery. When reducing power, this technique prevents the engine from overheating. After 40 hours a fault code will appear, which will stop the engine from starting. It is designed to protect you from damage to the engine or the Diesel Particulate Filter (DPF). DEF Pressure Sensor. I changed the filter but The CEL is still on and it's still in derate (won't rev higher than 1400 rpm) Do I need to clear the code before it will get out of the derate? Photo by Zetong Li on Unsplash. Fixing the underlying failures will help to clear derating codes permanently. Now, I own my garage in Miami, Florida. When the air filter is clogged, the amount of air required by the engine to reach optimum power is reduced. I love cars and love to share everything about them with my readers. Fuel Pressure Relief Valve.
The motor relief is designed so that when the ambient temperature exceeds the normal operating condition, the motor relief starts. If you're looking for diagnostic solutions that can give your drives and techs all the information they need about a derated DPF, then you need Jaltest tools. How does DPF regenerate? Put the key in the ignition with doors closed. Triad Diagnostic Solutions has all the heavy-duty code readers and software you're going to need. DEF Level & Temp Sensor.
I am an Automotive specialist. To find the best diagnostic tool for your fleet or repair shop, take a look here. Eaton uses this method of key cycles methods to retrieve: active, inactive, and to clear codes. In that case, it is best to use an OBD-II scanner to clear the codes. Active regeneration is a must for fleets that only drive local routes or don't reach the high temperatures necessary for passive regeneration. The machine will resume normal operation if it detects no errors for that duration. What Does a Derate Code Mean? During these instances, the engine undergoes a process to increase exhaust heat and create a chemical reaction that generates the high temperatures necessary for the DPF to oxidize particulate matter. It's Active fault 559 (engine injector metering rail 1) Looks to me like what happened is the Davco filter was plugged and it triggered the fault due to low fuel pressure. The engines are derated if the DEF system fails three times in the last 40 hours. Defects in the cooling system can lead to higher engine fluid temperatures, resulting in a greater reduction in engine power and increased fuel consumption.
Yeah right, I am the warranty!!! When the aftertreatment system in your heavy-duty fleet is working effectively, a regeneration of the DPF will occur while the truck is in transit. Each motor is designed to operate under specific conditions, such as environmental conditions. For example, if you have an electricity generator, you can reduce the derate of the motor to extend its life, even if the power in one direction is lower than in normal use. Attempting to clear the derate code before fixing the underlying problems will not permanently clear the code, the derate will come back.
