Intake Manifold Tuning (IMT) Valve (J35Z3 engine)

Engine power is adjusted by opening and closing the intake manifold tuning (IMT) valve. When the valve is closed, there is high torque at low engine speed. When the valve is open, there is high torque at high engine speed.
The intake manifold tuning (IMT) valve actuator has a sensor that detects the IMT valve position and sends it to the ECM.
