Description
WGV (Waste Gate Solenoid Valve) Control Solenoid Valve is installed side of the exhaust manifold and operates the WGT actuator which controls the by-pass passage of the turbo-charger turbine.When the turbine internal pressure is too high, the knocking phenomenon will occur in case of gasoline engine because of excessive operation of the compressor. So, in this case, in order to drop the turbine internal pressure, ECM restricts the turbine rotation by opening the by-pass passage.
