Intake Manifold Tuning (IMT) (Intake Manifold Runner Control (IMRC)) System

Intake Manifold Tuning (IMT) (Intake Manifold Runner Control (IMRC)) System

Engine power is adjusted by opening and closing the intake manifold tuning (IMT) (intake manifold runner control (IMRC)) actuator. 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) (intake manifold runner control (IMRC)) valve actuator contains a sensor that detects the IMT (IMRC) valve position and sends it to the PCM.
