Code P0404 2015 Chevrolet Silverado Description
The P0404 code for a 2015 Chevrolet Silverado indicates a problem with the Exhaust Gas Recirculation (EGR) system. Specifically, it means that the EGR valve is stuck in an open position, leading to a decrease in engine performance and increased emissions. The EGR system is responsible for recirculating a portion of the engine's exhaust gases back into the intake manifold to reduce combustion temperatures and minimize nitrogen oxide emissions. When the EGR valve is stuck open, it can result in poor fuel economy, rough idling, engine hesitation, and even stalling. If left unaddressed, this issue can lead to further damage to the engine and other emission control components.
