In engine terms, a 25 derate means the power output is reduced by 25%. Engine derate occurs when the engine computer limits power or speed to prevent damage.
It is essential to address the underlying issues causing the derate to maintain optimal engine performance and avoid further complications. Engine derating can be intentional to extend engine life or result from suboptimal operating conditions. Understanding the causes and levels of derate is crucial for effectively managing engine performance and ensuring efficiency.
By addressing derating promptly and accurately diagnosing the root cause, you can prevent potential damage and maintain optimal engine functioning in various applications.

Understanding Engine Derate
A derate means that the program inside the engine computer limits either the power or vehicle speed. It is designed to protect from causing engine or DPF damage. Various sensors or systems can cause a derate. Engine derating is the reduction of an engine’s output due to less-than-ideal operating conditions. Derating sometimes is done intentionally to prolong engine life and avoid substantial wear or damage.
If the system regularly runs low on DEF, things can become clogged and non-functioning in the DEF tank system. The truck might start derating due to regulatory and aftertreatment system fault codes. In case of a DEF derate, driving the truck with the SCR DEF derate bypass as a permanent solution to the problem is not recommended. Original DTC was poor DEF quality with engine derate. After deleting DEF, steps to clear the engine derate should be followed for resolution.

Troubleshooting Engine Derate
Engine derate is a term used to describe the reduction of an engine’s output under less-than-ideal conditions. This can be done intentionally to protect the engine from damage and prolong its life. Common signs of engine derate include lower power or restricted speed. To clear engine derate, address any fault codes and ensure proper maintenance of the exhaust aftertreatment system.
Def System And Engine Derate
DEF System and Engine Derate: A derate in the engine computer sets limits on power or speed to prevent damage from occurring. It happens when the system runs low on DEF, causing clogs and malfunctions.
Role of DEF System in Engine Derate: Engine derating is a method to protect the engine and avoid excessive wear. Low DEF levels can lead to clogs and malfunction, triggering the system to limit power or speed as a safety measure.
Common Issues with DEF System: Regularly running low on DEF can result in clogs and dysfunction within the DEF tank system, leading to engine derates and reduced performance.
Preventing DEF-related Derates: Checking DEF quality, sensor maintenance, and timely refills can help avoid engine derates caused by DEF system issues or malfunctions.
Consequences Of Ignoring Engine Derate
A derate means that the program inside the engine computer limits either the power or vehicle speed. It is designed to protect you from causing engine or DPF damage. It can be caused by various sensors or systems.
