At Maxim Fleet Service, we specialize in comprehensive emission system diagnostics and repair for all major semi-truck brands. Today’s trucks are held to strict emission standards, and problems with your DEF, DPF, EGR, or SCR systems can lead to power loss, warning lights, forced derates—or even downtime.
Our trained technicians use advanced diagnostic tools to accurately identify emission-related issues, including:
DPF (Diesel Particulate Filter) cleaning and replacement
DEF (Diesel Exhaust Fluid) system inspection and repair
EGR (Exhaust Gas Recirculation) valve and cooler service
SCR (Selective Catalytic Reduction) troubleshooting
Regeneration problems and fault codes
Sensor and wiring failures
We’ll walk you through the cause, provide a clear repair plan, and perform all necessary work to ensure your truck passes inspection and stays on the road. Whether you’re dealing with reduced engine power, poor fuel economy, or check engine lights related to emissions—we’ve got you covered.
Our team is trained on EPA-compliant repair procedures and equipped with the latest tools to ensure accuracy, efficiency, and peace of mind.
