The Chevy Duramax trouble code P140C indicates a problem with the exhaust gas recirculation system, specifically a slow response resulting in reduced flow. The EGR valve is a crucial component in managing emissions in diesel engines. By recirculating exhaust gases, the EGR system helps reduce NOx emissions by lowering oxygen levels in the combustion chamber and absorbing heat. If you find yourself needing to replace the EGR valve, be prepared for a moderately expensive repair. On average, the cost of EGR valve replacement falls between $340 and $430, with labor typically ranging from $90 to $110 and parts priced at $250 to $320. These costs may vary based on additional repairs and location-specific factors.
