DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Intake Manifold Runner Control Valve
Intake manifold runner control valve is consist of intake manifold runner control valve to open/close the right/left half section installed at each port of intake manifold runner control valve motor to drive open/close the valve.
ECM transmits the open/close signal to intake manifold runner control valve motor according to the driving condition based on the signals of engine speed, coolant temperature etc. ECM stabilizes combustion by causing strong swirl flow (revolving flow) by closing the intake manifold runner control valve.
INTAKE MANIFOLD RUNNER CONTROL VALVE MOTOR
Intake manifold runner control valve motor
is connected to the rear end of the valve shaft.
The motor opens or closes the valve by the output signal of the ECM.
INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION SENSOR
Intake manifold runner control valve position sensor
is connected to the front end of the valve shaft.
The sensor consists of variable resister. It senses the valve shaft movement and feeds the voltage signals to the ECM.
