What happens if the runner control valve is stuck?
What happens if the runner control valve is stuck?
Each intake runner control valve is controlled by the ECU for precise timing to maximize performance and efficiency. If a runner control valve is stuck, it can cause too much or too little air to enter the cylinder, negatively affecting performance and fuel economy. This may also illuminate the Check Engine light.
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 causes intake manifold runner control ( IMRC ) to shorted?
P2004 FORD Possible Causes Intake Manifold Runner Control (IMRC) monitor signal shorted to power Faulty Intake Manifold Runner Control (IMRC) actuator Faulty Intake Manifold Runner Control (IMRC) solenoid Damage Powertrain Control Module (PCM)
Can a faulty IMRC valve cause engine problems?
In many cases, an illuminated check engine light will be the only indicator that the valve is faulty. A faulty IMRC valve can throw off the engine’s air/fuel mixture, leading to performance problems.
Where is the short runner valve on a car?
The short runner valve on your car is a valve in the intake that directs airflow either through the long intake runners or around them. The short runner valve actuator is the electric motor that moves the short runner valve to it’s correct position.
