Hyundai Accent (HC) (2017 - 2022) Service Manual: Variable Intake Solenoid (VIS) Valve

- Description Variable Intake manifold Solenoid (VIS) valve is installed on the intake manifold. The VIS valve controls the vacuum modulator which activates a valve in the intake manifold. The ECM opens or closes this valve according to engine condition (Refer to below table). Engine conditionVIS valveOperation Medium speedClosedIncreasing engine performance in low engine speed by reducing intake interference among cylinders Low / High speedOpenMinimizing intake resistance by shortening intake manifold length and increasing area of air entrance - Specification ItemSpecification Coil resistance (Ω)30.

Hyundai Accent (HC) (2017 - 2022) Service Manual: 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.
