Intake Manifold runner control stuck open - bank one:
- Intake Manifold Runner Binding Or Sticking
- Faulty Manifold flow valve
- Manifold flow valve harness is open or shorted
- Manifold flow valve circuit poor electrical connection

There is a factory service bulletin for this problem for 2007-2008 Dodge Avengers. (JS)

2004 ford f 150 5.4 3V pulled intake fixed vac hose came off replaced imrc & still show intake runner control closed bank 1 Still has no power when I get in it to pass something any ideas?


Is your check engine light on ? Any codes ?

There are three basic types of intake air sub-systems:


  • Intake Manifold Runner Control (IMRC) electric actuated system

  • Intake Manifold Swirl Control (IMSC) vacuum actuated system

  • Intake Manifold Tuning Valve (IMTV)

These subsystems are used to provide increased intake airflow to improve torque, emissions and performance. The overall quantity of air metered to the engine is controlled by the throttle body.

Intake Manifold Runner Control (IMRC) Electric Actuated System
The Intake Manifold Runner Control (IMRC) Electric Actuated system (Figure 107) consists of a remote mounted motorized actuator with an attaching cable for each housing on each bank. Some applications will use one cable for both banks. The cable or linkage attaches to the housing butterfly plate levers. The 2.0L (2V) Focus IMRC uses a motorized actuator mounted directly to a single housing without the use of a cable. Each IMRC housing is an aluminum casting with two intake air passages for each cylinder. One passage is always open and the other is opened and closed with a butterfly valve plate. The housing uses a return spring to hold the butterfly valve plates closed. The motorized actuator houses an internal switch or switches, depending on the application, to provide feedback to the PCM indicating cable and butterfly valve plate position.



Below approximately 3000 rpm, the motorized actuator will not be energized. This will allow the cable to fully extend and the butterfly valve plates to remain closed. Above approximately 3000 rpm, the motorized actuator will be energized. The attaching cable will pull the butterfly valve plates into the open position. Some vehicles will activate the IMRC near 1500 rpm.



WARNING: SUBSTANTIAL OPENING AND CLOSING TORQUE IS APPLIED BY THIS SYSTEM. TO PREVENT INJURY, BE CAREFUL TO KEEP FINGERS AWAY FROM LEVER MECHANISMS WHEN ACTUATED.




  1. The PCM uses the TP sensor and CKP signals to determine activation of the IMRC system. There must be a positive change in voltage from the TP sensor along with the increase in rpm to open the valve plates.




  1. The PCM uses the information from the input signals to control the IMRC motorized actuator based upon rpm and changes in throttle position.




  1. The PCM energizes the actuator to pull the butterfly plates open with the cable(s) or linkage.




  1. The IMRC housing contains butterfly plates to allow increased air flow.

P2004 intake valve stuck open


code p2004 refers to intake manifold air control actuator-bank 1--actuator stuck open===Causes---wiring--intake manifold air control actuator---mechanical fault .I would check blockage and wire connections Then I would replace the actuator But I would not tear down the engine as it is between the air filter and the manifold. Check the air cleaner element

Whats is Service Engine Code P1800 - VIAS Control Solenoid Valve Circuit Open


Here is the definition. Cost would depend on your area and the actual problem found after testing.

P1800 NISSAN Description When the engine is running at low or medium speed, the power valve is fully closed. Under this condition, the effective suction port length is equivalent to the total length of the intake manifold collector's suction port including the intake valve. This long suction port provides increased air intake which results in improved suction efficiency and higher torque generation.
The surge tank and one-way valve are provided. When engine is running at high speed, the Engine Control Module (ECM) sends the signal to the Variable Intake Air System (VIAS) control solenoid valve. This signal introduces the intake manifold vacuum into the power valve actuator and therefore opens the power valve to two suction passages together in the collector.
Under this condition, the effective port length is equivalent to the length of the suction port provided independently for each cylinder. This shortened port length results in enhanced engine output with reduced suction resistance under high speeds.

Engine code P1800 for infiniti I35, how do I fix this?


Code 1800 is for the Variable Intake Air System control solenoid.

The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the power valve actuator. An excessively low or high voltage signal is sent to ECM through the valve

Hi i have 02 altima 3.5 v6 who have check engine light with code p1800 what is manufactured transmission control can anyone help me what that means?


You may want to have someone else take a look at it. The Nissan P1800 trouble code is not a transmission control problem. It is described as follows:

Trouble diagnosis name: VIAS control solenoid valve circuit.
Component Description:
The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the power valve actuator.
DTC detecting condition:
•An excessively low or high voltage signal is sent to ECM through the valve.
Possible cause:
•Harness or connectors (The solenoid valve circuit is open or shorted.)
•VIAS control solenoid valve

Check your vacuum hoses to make sure they are in good shape and are securely attached Aslo check the wiring harness is ok and securely attached as well. If they are, you’ll probably need to replace your VIAS. It's right next to the throttle body.

Engine noise


Sounds like a problem with the power valve actuator in the intake manifold collector. I would check with a Nissan dealer first and inquire of any recalls or service bulletins. Might save ya time & money.

Rattle when accelerating


had the same issue, had someone look and it seems the noise was caused by heat shield being loose covering exhaust system. Have that checked out.

Take a look at Nissan Technical Service Bulletin NTB05-15b. Title = "Rattle Noise From Vias Power Valve Actuator / Intake Manifold Collector" This appears to describe your problem exactly. I have the same problem with my 2005 Xterra and I am going to try the recommended fix myself at home.
