Code P2006 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. 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 plates closed. The motorized actuator houses internal switches to provide feedback to the Powertrain Control Module (PCM), indicating linkage and plate position. Under about 3000 rpm, the vacuum solenoid will be energized. This will allow the manifold vacuum to be applied and the butterfly valve plates to stay closed. Above approximately 3000 rpm, the vacuum solenoid will be de-energized. This will allow a vacuum to vent from the actuator and the butterfly valve plates to open. The Diagnostic Trouble Code (DTC) sets when the IMRC is commanded open, but the IMRC monitor indicates close.

2. What does the OBDII code P2006 indicate?

- The code P2006 indicates that the Intake Manifold Runner Control (IMRC) is stuck closed on Bank 1 of the engine.

3. What are the possible causes of the Intake Manifold Runner Control being stuck closed?

- Potential causes include a faulty IMRC actuator, carbon buildup in the intake manifold, or electrical issues.

4. How can I diagnose the issue causing OBDII code P2006?

Discuss the causes and fixes for P2006 OBDII Code

  • could this be a short runner actuator valve

  • What make, model and year is your vehicle? 

  • I got his P2006 on my Ford Freestar 4.2L 2004, what It can be the cause?

  • Got this code on my 2010 Kia Forte

  • Got this on my wifes 2011 Kia Sportage the other day. Does this require an entire Intake Manifold replacement?

  • Please double check the code, there is no information on the factory service manual for the P2006 code.

  • Thanks, I'll have a different mechanic check it. The info came from my regular mechanic.

  • Hi..received this code from the dealership for my 2011 Hyundai tuscon. They recommend replacing the whole intake manifold. Is there not a repair for this?

  • According to the factory service manual the most likely cause of the code is the Variable Charge Motion Actuator (VCMA)

  • thank you. Assume then i don't need my whole intake manifold replaced that did sound a bit crazy

  • Hi!
    The p2006 code, p2181 and also the p1128 code has shown up on my 2010 dodge caliber rush (4 cyl.-2.4 liter) .

    The abs light and engine light is on. After driving my car for atleast an hour, when it is warm outside (takes longer in cold weather) , my car will drop down to 2and gear and won't go over 30 mph and it makes a horrible grinding like noise.

    So I'm assuming that I need to replace the thermostat and the o2 sensors on bank 1. On the p2006 it said that my intake manifold running control stuck closed bank 1A. -----i don't know what I should do with that.

    On a side note, I know nothing about cars. Ive spent days googling this stuff. Can someone help me out on what to do with all this?

  • You are correct about the P2181 code, the thermostat is the most common cause of this code. You should hold the O2 sensor for P1128 code, according to a national database of repairs for your model and year, the Positive Crankcase Ventilation (PCV) Valve could cause the P1128 and P2006 code. I suggest replacing the thermostat and PCV Valve (which are both parts of regular maintenance), clear the codes and go from there.
