What does the flapper valve on the intake manifold do?
What does the flapper valve on the intake manifold do?
I have heard these called many names but a “flapper” valve comes up often in the repair world. The 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.
What is the purpose of an intake manifold tuning valve?
One of the systems that your ECM is responsible for monitoring and correlating with desired values is, the Intake Manifold Tuning Valve. I have heard these called many names but a “flapper” valve comes up often in the repair world. The intake manifold tuning valve has multiple possible purposes to aid in your engine’s performance and drivability.
What kind of material is the intake valve made of?
The valve itself, from my experience anyway, is made mostly of plastic so you can imagine some possible malfunctions in combination with notoriously high temperatures in the engine compartment.
How to replace the intake manifold in a Lincoln Navigator?
How to Replace the Intake Manifold in a Lincoln Navigator. The Lincoln Navigator is the first full-size luxury SUV offered by a domestic auto maker. Because of its size and flash, it was regarded for its first few years as a status symbol.
Where is the tuning valve on the intake manifold?
First, you will need to locate the intake manifold tuning valve. This may be difficult because more often than not they are mounted internally, in the intake manifold itself. Having that said, the connector for the valve should be fairly accessible, so visually inspect it, looking for broken tabs, melted plastic, etc.

How do you remove the upper intake manifold from a car?
Lift the manifold from the engine and disconnect the IM Tuning Valve (IMTV) connector. Pull the upper intake gaskets and discard them. Use a ratchet to remove the upper-to-lower manifold bolts then separate the two units. Remove the gasket and discard it. Set the upper manifold onto the lower manifold.
How does the intake manifold control valve work?
The intake runner control valve diverts air to longer, narrow runners during low RPMs, and shorter, wider runners for higher RPMs. Each intake runner control valve is controlled by the ECU for precise timing to maximize performance and efficiency.
What is the diagnostic code for intake manifold tuning valve?
P0660 is a diagnostic trouble code (DTC) for “Intake Manifold Tuning Valve Control Circuit/Open Bank 1”.
Where is the intake manifold Runner Control located?
Jan 11th 2016 at 1:38PM. The intake manifold runner control is an engine management component that is found on newer intake manifold designs. 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.
Why does my intake manifold runner light come on?
Check Engine Light comes on. An illuminated Check Engine Light is another symptom of a possible issue with the intake manifold runner control. If the computer detects an issue with the intake manifold runner control position, signal, or circuit, it will set off the Check Engine Light to alert the driver of the issue.
