P2006 Code Help: Intake Manifold Runner Control Stuck Closed - What to Do?

I’ve been dealing with the P2006 diagnostic trouble code lately, and I’m really hoping to get some advice on what steps I should take next. For those who aren’t familiar, this code is related to the intake manifold runner control (IMRC) and indicates that it’s stuck closed on bank 1. My car has been showing some signs of poor performance, particularly during acceleration, and the check engine light is constantly on.

What’s Happening?

From what I’ve read, a stuck closed IMRC can lead to a variety of issues:

  • Reduced Engine Performance: The car feels sluggish, especially at higher RPMs.
  • Poor Fuel Economy: I’ve noticed that I’m filling up more often than usual.
  • Check Engine Light: It’s been on, and this code keeps popping up.

Initial Checks

Before I dive deeper, here’s what I’ve done so far:

  1. Checked the Codes: My OBD-II scanner confirmed the P2006 code.
  2. Visual Inspection: I looked at the intake manifold and related components but didn’t see any obvious damage.
  3. Cleared the Code: I cleared the code to see if it comes back, and it did after a short drive.

Questions for the Experts

  • What’s the likely cause? Is this usually a fault with the actuator or the manifold itself?
  • DIY Solutions? Are there any steps I can take to troubleshoot this before taking it to a mechanic?
  • Potential Costs? If I do need to replace parts, what can I expect in terms of cost?

I really appreciate any tips or insights you all might have. I want to resolve this issue as soon as possible, so any advice or guidance would be super helpful!

I’ve dealt with the P2006 code before. One major symptom is a noticeable drop in engine performance. You might also experience a rough idle or warning lights on your dashboard.

Absolutely! I also noticed my fuel economy took a hit when my intake manifold runner was stuck closed. It was a pain at the pump!

I experienced similar symptoms. The check engine light came on, which led me to investigate further. I ran a code reader and confirmed the P2006 code as well.

Were there any other codes that came up with the P2006? Sometimes it’s not just the intake runner control that needs checking.

Good question, Carla! I only got the P2006 code. It’s strange how one small component can affect so much!

For diagnostic steps, I first visually inspected the intake manifold and actuator for any obvious damage or blockage. Didn’t find anything at first, but that’s where I started.

I went straight to checking the vacuum lines and electrical connections. Corroded or disconnected wiring can cause the runner to malfunction.

That’s a solid first step! I ended up replacing the actuator after finding it was faulty. Fixed my issue!

I had both poor performance and a rough idle. It really felt like the car was having a bad day! Has anyone tried the cleaning steps?

Haha, sounds like your car needs some vitamin booster! A good cleaning definitely helped with my problem.

Thanks everyone for sharing! It’s clear that this issue can affect various parts of performance. Definitely need to take a closer look at my intake system now.

I’ve had a P2006 code before! It typically points to issues with the intake manifold runner control. First, check the actuator for any damage or electrical problems.

Thanks for the tip! Could wiring problems also be the culprit? Sometimes the connectors get corroded.

Definitely check the wiring, estradavicki. I replaced my actuator and cleaned up the connectors, and it fixed my issue. Also, make sure there are no vacuum leaks.

That sounds like a solid plan! Is it hard to replace the actuator yourself?

Not difficult, hannahthompson! Just a few bolts and wire connections. Make sure to have the right tools ready. If you feel unsure, watch some YouTube tutorials!

If only all car repairs were that easy! What if it’s just a vacuum hose issue? Would that trigger the same code?

Great point, cruzgeorge! Vacuum leaks can absolutely trigger the P2006 code. I had a small crack in my vacuum hose that caused similar problems.

Always the little things, right? I never thought a tiny crack could cause such a headache!
