Where is the intake runner control?

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.

What is a variable intake manifold runner valve?

But now, some vehicles have a variable intake manifold (also known as an intake manifold runner control system). The updated design varies the length of the manifold’s runners with the help of an intake manifold runner control (IMRC) valve. The IMRC valve is the part of the intake manifold system that opens and closes the flaps.

What are the flaps on an intake manifold?

Most systems have flaps (or butterfly valves) inside the manifold that vary the runner length. An electric or vacuum-operated actuator controls the flaps. On vehicles where a vacuum source is used, a solenoid supplies vacuum to the actuator.

How does a solenoid work in a variable intake manifold?

On vehicles where a vacuum source is used, a solenoid supplies vacuum to the actuator. A typical variable intake manifold system with an electronic actuator. Usually, the flaps control access to two separate pathways for airflow: one short and one long.

What to do if your intake manifold Runner Control is bad?

Step 1: Clear the codes. If the indication of a bad intake manifold runner control was a check engine light and an accompanying trouble code, clear the engine computer after the job. OBD II scanners have become very affordable so they are accessible to the home mechanic.
