What is the function of the butterfly valve?
What is the function of the butterfly valve?
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.
What do the butterfly valves on an intake manifold do?
At high speeds/RPM, the IMRC butterfly valve plates will open to allow the flow of air into the intake system, and at low speeds/RPM, the IMRC butterfly valve plates will close to restrict the flow of air into the intake system.
Why do butterfly valve plates open and close?
The plates then open and close to allow or restrict air from entering into the intake system. At high speeds/RPM, the IMRC butterfly valve plates will open to allow the flow of air into the intake system, and at low speeds/RPM, the IMRC butterfly valve plates will close to restrict the flow of air into the intake system.
How to test the IMRC butterfly valve plates?
Uses the scan tool to test the IMRC solenoid: Open and close the IMRC solenoid using the scanner. If the IMRC solenoid does not respond, the solenoid will need to be replaced. Replacing the IMRC butterfly valve plates when the problem was that they were not connected properly
