What do you need to know about intake manifold runners?
Traditional designs have a fixed length and width. 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.
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.
How are intake runners connected to the plenum?
Intake runners are the actual tubes that channel intake air from a reservoir, known as a “plenum” to the intake ports. The image above shows a typical intake manifold, on which the runners connect to the plenum individually, as opposed to branching off from a single exit point as was usual on older manifolds.
What happens when you have a bad intake manifold?
If you have a bad intake manifold, the air-fuel mixture will get different than what it is supposed to be, and therefore the check engine light will show up on your dashboard. When the check engine light shows up – there is also a trouble code stored in the engine control unit that you need to read to continue the troubleshooting.
Where is the intake manifold Runner position sensor?
Code P2015 stands for Intake Manifold Runner Position Sensor Range Bank 1. The intake manifold sits on top of the engine between the cylinder heads. Runners inside the manifold deliver air to the engine via a series of runners.
What are the symptoms of a bad intake valve?
A typical symptom of bad valve seals/guides is you will notice oil/deposits built up on the side of the spark plug facing the intake valve. With worn rings, usually the entire tip of the plug will have oil/deposits on it.
What are variable intake manifolds?
In internal combustion engines, a variable-length intake manifold ( VLIM ), variable intake manifold ( VIM ), or variable intake system ( VIS) is an automobile internal combustion engine manifold technology. As the name implies, VLIM/VIM/VIS can vary the length of the intake tract – in order to optimise power and torque across the range of engine speed operation, as well as help provide better fuel efficiency.
What is a variable intake manifold?
In internal combustion engines, a variable-length intake manifold ( VLIM ),variable intake manifold (VIM), or variable intake system (VIS) is an automobile internal combustion engine manifold technology.
What is the intake manifold runner code for a Kia Sorento?
P200a intake manifold runner code. 2011 kia sorento 2.4 liter 4 cylinder. – YouTube P200a intake manifold runner code. 2011 kia sorento 2.4 liter 4 cylinder. If playback doesn’t begin shortly, try restarting your device.
Why does the intake manifold tumble on a Kia?
The valve restricts air flow, causing it to tumble or swirl. The tumbling action helps ensure that the fuel and air mix thoroughly and burn faster. The intake manifold flow control valve and variable valve timing work together to improve fuel economy, idle stability, and emissions.
What causes a manifold to stick on a p200a Kia?
P200A KIA Possible Causes 1 Intake Manifold Runner Binding Or Sticking 2 Faulty Manifold flow valve 3 Manifold flow valve harness is open or shorted 4 Manifold flow valve circuit poor electrical connection
What is the runner control on an intake manifold?
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 does an intake manifold do in a car?
Your car has an intake manifold that distributes air into the engine’s cylinders. Traditional designs have a fixed length and width. But now, some vehicles have a variable intake manifold (also known as an intake manifold runner control system).
