Intake Manifold Communication Control (MPV)

The Intake Manifold Communication Control (IMCC) actuator in the intake manifold controls the length of intake air path, depending upon engine RPM. With engine speed less than 3750 RPM, the IMCC actuator is energized, improving torque output. At more than 3750 RPM, the IMCC actuator is de-energized, increasing airflow while improving high RPM performance. The PCM monitors the IMCC actuator at all times.
