What does an intake manifold runner control do?
What does an intake manifold runner control do?
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 an intake manifold runner position sensor?
The runner position sensor, also known as the runner valve, controls the volume of air entering the intake manifold. The runner valve controls a flap in the intake manifold, which will open or close depending on the air requirements of the engine. It is designed to help optimize the air-fuel ratio (AFR) of the engine.
What causes an intake manifold runner to get stuck?
Possible causes for this engine code include: 1 Defective IMRC actuator solenoid 2 Loose or binding intake manifold runners 3 Bad intake manifold runner position sensor 4 Open or shorted wiring in the IMRC actuator solenoid control circuit 5 Faulty MAP Sensor 6 Corroded IMRC actuator solenoid connector face More
What is the Ford intake manifold runner control?
P1537 FORD Description The Intake Manifold Runner Control (IMRC) is an electrically actuated system consisting of a motorized actuator with an attaching linkage for each housing on each bank. The linkage attaches to the housing butterfly plate levers. Each IMRC housing is an aluminum casting with two intake air passages for each cylinder.
How to diagnose Ford P2004 intake manifold control?
Start by checking the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The cost to diagnose the P2004 FORD code is 1.0 hour of labor.
Can a vacuum diaphram control an intake manifold?
Finally, sometimes it is achieved by a vacuum diaphram instead. If this is the case, it will be controlled by an electronic intake manifold solenoid. If you suffer from a intake manifold runner control that is stuck open, there are a few symptoms you will probably notice.
