The Exhaust gas recirculation (EGR) system is vital because it recirculates exhaust back into the engine cylinders, replacing some air with nitrogen oxide to reduce emissions. The EGR feedback pressure hose is the primary connection between the components of the EGR valve.
EGR pressure feedback hoses functionThe EGR pressure feedback hoses are an essential part of the EGR system because it connects the components of the EGR. The hose is known to deal with excessive heat from the exhaust and it is susceptible to cracking over time. The EGR pressure feedback hose must remain in good working condition to prevent damage to the vehicle.
Common issues with a faulty EGR pressure feedback hoseA defective EGR pressure feedback hose can lead to rough idling, clunking noises, or an increase in emissions.
