Service Overview
A derate is a symptom. Find the underlying fault.
YourWay Diesel Repair & Fleet Services provides DPF, DEF, SCR and derate diagnostics for commercial trucks. A derate limits engine performance in response to a condition detected by the vehicle. The dashboard message alone does not establish which component needs repair, and reduced power is not always caused by the same aftertreatment fault.
The diesel particulate filter collects soot from the exhaust. Regeneration removes soot buildup under the required operating conditions. DEF is used in the SCR system to help control nitrogen-oxide emissions. DPF loading, DEF-related faults, NOx-sensor information and other aftertreatment data need to be evaluated in the context of the truck’s fault codes and symptoms.
YourWay can assess aftertreatment concerns and perform a forced regeneration when diagnosis and the manufacturer’s conditions make it appropriate. A regeneration is not a universal repair for a DEF, SCR or sensor fault. Describe failed regeneration attempts and recent work, and provide photos of the dashboard messages if available. Service focuses on diagnosis and compliant repair, not emissions deletes or bypasses.
Call 901-791-7948 or request derate diagnostics with the truck and engine details, warning messages and current operating condition. The Memphis shop is at 2709 Chelsea Ave. Related concerns may need electrical diagnosis or broader diesel diagnostics.

Answers for fleet managers, owner-operators, dispatch teams, and businesses comparing service partners in Memphis, TN.
A derate is an engine-control response to a detected condition. Aftertreatment faults are one possible cause, but the exact warning, fault data and system checks are needed to identify the reason.
Yes, when diagnosis and the vehicle manufacturer’s required conditions support it. A forced regeneration does not resolve every DEF, SCR, sensor or engine problem.
Include the truck year, make, model, engine, warning messages, current symptoms and recent repairs. Call 901-791-7948 before arranging service if the truck has reduced power or limited drivability.
