Hyundai Accent (HC): Engine Control System / Electric EGR Control Valve

Hyundai Accent (HC) (2017 - 2022) Service Manual / Engine Control / Fuel System / Engine Control System / Electric EGR Control Valve

- Description The Electric EGR Control Valve is installed in between the EGR cooler and the exhaust line and is a solenoid valve. This valve controls EGR (Exhaust Gas Recirculation) amount by the ECM's duty control signal depending on engine load and the need of intake air.The Exhaust Gas Recirculation (EGR) system is used to add the exhaust gas to intake air in order to reduce an excess of air and the temperature in the combustion chamber.

- Installation

   

• Install the component with the specified torques.

• Note that internal damage may occur when the component is dropped. In this case, use it after inspecting.

   

• Be careful of foreign material not to flow into the valve.

1.Install in the reverse order of removal.
