A Guide to the 2002-2006 Honda CR-V Intake Manifold Runner Control Valve
Is your second-generation CR-V feeling sluggish or throwing a check engine light? The IMRC valve could be the culprit.
- A faulty IMRC valve on a 2002-2006 CR-V typically causes a check engine light with codes like P2004, P1077, or P1078.
- Symptoms include poor acceleration, rough idle, and decreased gas mileage.
- Replacement requires removing the intake manifold, making it a moderately difficult DIY job.
- A quality aftermarket brand like Standard Ignition offers a reliable, cost-effective alternative to expensive OEM parts for this repair.
Is My Intake Manifold Runner Control Valve Failing?
A faulty IMRC valve can disrupt your CR-V's engine performance. Because it controls airflow, a failure can lead to a noticeable drop in power, poor fuel economy, and a rough idle. The most common sign is a check engine light on your dashboard.
Common Trouble Codes
If your check engine light is on, a code scanner will likely show one of these diagnostic trouble codes (DTCs) for a failing IMRC system:
- P2004: Intake Manifold Runner Control Stuck Open.
- P1077 / P1078: Often related to the IMRC system malfunction.
- P0661: Intake Manifold Tuning Valve Control Circuit Low.
Choosing the Right Aftermarket Part
When replacing the IMRC valve on your 2002-2006 CR-V, you have the choice between original equipment (OEM) from Honda or an aftermarket part. For this specific component, aftermarket options can provide good value. The key is to choose a reputable brand.
Standard Ignition (Standard Motor Products): This is a well-known aftermarket brand that has been around for a long time. Their parts are designed as direct-fit replacements and are often built to meet or exceed original specifications using quality materials. For a vehicle of this age, a quality aftermarket part from a brand like Standard Ignition is a reliable and cost-effective choice compared to a more expensive OEM part.

Known Issues & Recalls
While there are no specific recalls or Technical Service Bulletins (TSBs) from Honda for the IMRC valve on the 2002-2006 CR-V, failures are a known issue. The most common cause of failure is the internal diaphragm tearing or carbon buildup preventing the valve from moving freely. Sometimes, the vacuum lines connected to the solenoid can also crack or come loose, causing similar symptoms.
It is important to note that this CR-V generation was subject to recalls for other issues, such as the driver's side power window switch and Takata airbags, but not the intake system.
Pro Tip: Check Before You Replace
Before buying a new valve, it's worth inspecting the vacuum hoses connected to the IMRC solenoid. These hoses can become brittle and crack over time, creating a vacuum leak that mimics a failed valve. A simple visual inspection could save you time and money.
Frequently Asked Questions (FAQ)
What are the main symptoms of a bad IMRC valve on a CR-V?
The most common symptoms are a check engine light, reduced engine power (especially at low or high RPMs), rough idling, and a decrease in fuel economy. You might notice the engine feels sluggish or hesitant to accelerate.
Can I clean the IMRC valve instead of replacing it?
Sometimes, cleaning can solve the problem if it's caused by carbon buildup that is making the valve stick. However, if the internal diaphragm has failed or there is an electronic issue with the sensor, cleaning will not work and the part must be replaced.

This is a moderately difficult job for a DIY mechanic. It requires removing the entire intake manifold to access the valve, which is held on by three bolts. The process involves disconnecting several hoses and electrical connectors. If you are not comfortable with this level of work, it's best to have a professional mechanic do it.
