- The Intake Manifold Tuning Valve (IMTV) is a motorized actuated unit mounted directly to the intake manifold1234. It controls a shutter device attached to the actuator shaft, which can be used to regulate pressures between intake plenums, redirect intake air to a separate set of intake runners, or alter the length of the runners to fine-tune the engine's performance2354. The valve is usually motorized or vacuum actuated and attached to the intake manifold, and controls the opening and closing of butterfly valves inside of the intake manifold runners4.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.The Intake Manifold Tuning Valve (IMTV) is a motorized actuated unit mounted directly to the intake manifold. The IMTV actuator controls a shutter device attached to the actuator shaft. There is no monitor input to the Powertrain Control Module (PCM) with this system to indicate shutter position.www.engine-codes.com/p2076.htmlThe intake manifold tuning valve has multiple possible purposes to aid in your engine's performance and drivability. One is to regulate pressures between intake plenums. The other may be to redirect intake air to a separate set of intake runners (or combination) to change to flow and possibly the performance of your engine.www.obd-codes.com/p0660The primary chore of the intake manifold runner valve is to improve the engine airflow process and ensure optimal engine performance. The valve achieves this chore by diverting airflow and altering the length of the runners. Altering the length of the runners allows the fine-tuning of the engine’s performance.carsamazing.com/what-is-the-ultimate-role-of-the-i…It is usually a motorized or vacuum actuated unit attached to the intake manifold, that controls the opening and closing of butterfly valves inside of the intake manifold runners. The unit will open and close the butterfly valves in order to provide maximum manifold pressure and flow at all engine speeds.www.yourmechanic.com/article/symptoms-of-a-ba…Intake manifold vacuum is applied to the variable tumble shutter valve actuator by the operation of the variable tumble solenoid valve, closing the variable tumble shutter valve. At this time, the intake passage is narrower than normal, increasing intake airflow speed and also creating a powerful air tumble in the combustion chamber.www.focusfanatics.com/threads/duratec-intake-tuni…
