Light-Duty Diesel EGR & DPF Shop
The exhaust gas recirculation system (EGR) and diesel particulate filter (DPF) in diesel pickup trucks function to reduce and filter emissions and are now standard in light-duty diesel pickup truck models. The EGR system recirculates exhaust gases through the engine cylinders a second time, cooling them in the process. This cooling of the combustion temperature helps reduce nitrogen oxide levels in the vehicle's exhaust, leading to cleaner emissions.
Much of this process is controlled by a valve in the EGR system, the EGR valve, which functions to redirect exhaust to the inlet manifold instead of directly to the exhaust manifold. Over time, EGR components can get dirty from the particulate matter in exhaust gases and become clogged with soot. Issues that can occur in an EGR system include soot and carbon buildup in EGR valves, cracks within the EGR cooler, issues with sensors, electrical problems, and coolant leaks.

Since the EGR system is an intermediary between the engine and after-treatment systems, failures in the EGR can lead to larger problems in those components as well. Carbon buildup in the EGR itself can result in a decline in vehicle performance and efficiency, including increased fuel consumption, slower or sluggish engine acceleration, and rough idle. Issues with the EGR can also be indicated by black smoke coming from a diesel truck's exhaust, with a defective or clogged EGR valve often being the source of the problem.
Our service center can run diagnostics on the pickup truck's engine and exhaust system to pinpoint whether the EGR is causing a given problem. Once the issue is diagnosed, mechanics can remove carbon buildup by cleaning the EGR system.
