EGR & DPF Repair Services in Rochester, NY

About Our EGR & DPF Repairs & Services for Trucks & Fleets

Your EGR System

The EGR system helps decrease NOx emissions in a heavy-duty engine by lowering the combustion temperature. Here’s how it works. The higher the temperature, the more NOx is generated. The EGR system takes some of the exhaust gases and recirculates them back into the engine instead of letting them out through the exhaust pipe. Next, an EGR cooler cools the exhaust gases before reintroducing them into the engine. From here, a valve regulates the amount that is recirculated, making your truck’s engine more environmentally friendly. 

Your DPF System

When you see a modern heavy-duty truck, chances are that it integrates a DPF component. It is designed to accumulate soot and other debris before it exits the exhaust system. As the DPF has a limited storage capacity, it may enter Automatic Regeneration mode periodically to burn off stored material and make space for more. However, the DPF may become clogged sometimes before it reaches full capacity. In such cases, our technicians at PNS Truck Repair can manually activate the DPF's regeneration mode to clear out any debris.

Signs of EGR Complications

EGR systems in today’s trucks are susceptible to two mechanical troubles. 

• Malfunctioning EGR valves: Carbon buildup caused by exposure to unfiltered emissions can cause the EGR valves to seize up, resulting in an uncontrolled exhaust recirculation system and potentially severe engine damage. 
• Leaks in the EGR coolers: Leaks can cause coolant to mix with the exhaust gases and be sent back into the engine. This not only damages your engine but also affects your truck’s overall performance.

Why Does My Semi Truck Keep Going Into DPF Regeneration?

Frequent DPF regeneration may point to excessive soot production, faulty temperature or pressure sensors, EGR problems, injector issues, or a filter that is no longer cleaning effectively. Proper aftertreatment diagnostics can identify the root cause instead of treating repeated regens as the only problem.

What Causes a Diesel Truck to Enter Derate Because of the Aftertreatment System?

Aftertreatment derate can result from DPF restriction, EGR faults, DEF system problems, failed sensors, or unresolved emissions-related fault codes. Diesel diagnostics can pinpoint which part of the system triggered the derate so technicians can correct the issue and restore normal engine performance.

Can EGR and DPF Problems Cause Loss of Power in a Diesel Truck?

Yes. Restricted exhaust flow, excessive soot buildup, a sticking EGR valve, or incorrect sensor readings can reduce engine power and throttle response. EGR and DPF repair focuses on identifying the failed component or restriction before the truck experiences repeated derates, regens, or downtime.
