What Does The P2006 Code Mean?

The P2006 diagnostic trouble code (DTC) indicates a malfunction in the intake manifold runner control (IMRC) system. Though this is a generic code that can happen on all vehicles equipped with OBD-II, it is more commonly triggered in Mercedes, Audi, Ford, Hyundai, Mazda, Volkswagen, Kia, Dodge, and Jeep.

The intake manifold runner control system is designed to optimize the airflow into the engine for improved performance and efficiency. It consists of several components, including the intake manifold, intake manifold runner control valve, actuator motor, and linkage. These components work together to adjust the length of the intake runners, which helps optimize the intake air velocity and maximize engine power and torque across different RPM ranges.

When the P2006 code is triggered, it means that the powertrain control module (PCM) has identified a problem with the IMRC actuator for engine bank 1. Specifically, the actuator is detected to be stuck in the closed position. This issue hinders the proper functioning of the IMRC system, leading to disrupted airflow and negatively impacting the engine’s performance.

The P2006 code shares similarities with other codes related to the IMRC system. They are P2005, P2007, P2008, P2009, P2010 and P2015.

Special Notes

To address this issue, car manufacturers have issued Technical Service Bulletins (TSBs) or recall campaigns. For example, Ford and Mercury have released TSB 06-7-10 related to the P2006 code. Audi has also issued a TSB regarding this code. Additionally, Mazda has a recall campaign specifically addressing the P2006 code in certain models.

These TSBs and recall campaigns provide guidance for diagnosing and repairing the intake manifold runner control system to resolve the P2006 code. It is important for car owners experiencing this issue to consult the specific TSB or recall campaign relevant to their vehicle make and model to ensure proper solutions for your vehicle.

How Serious is the P2006 Code and Should You Continue Driving?

The severity level of the P2006 code is high. While it may not cause immediate drivability issues or safety hazards, it can significantly impact engine performance and fuel efficiency. Ignoring the P2006 code can lead to a reduction in engine power, decreased fuel economy, and potential long-term damage to the engine or emission control system.

Although you may be able to continue driving for a short period of time with the P2006 code, it is strongly recommended to have the issue diagnosed and repaired as soon as possible. Continuing to drive without resolving the P2006 code can decrease drivability and lead to increased repair costs over time.

P2006 Code Symptoms and Indicators

When the P2006 code is present, several symptoms may be observed.

Check Engine Light (MIL) illuminated
Reduced engine power or hesitation during acceleration
Decreased fuel efficiency
Rough idle or stalling

Possible Causes of P2006 Code

There are various potential causes for the P2006 code.

Stuck or malfunctioning IMRC valve
Faulty actuator motor or linkage
Vacuum leaks in the intake manifold
Carbon buildup within the IMRC system, particularly on the IMRC flaps or intake manifold ports
Open or shorted wiring within the solenoid control circuit for the IMRC actuator
Broken actuator linkage pin between the actuator and the runner control valve.
Faulty MAP sensor
Issues with the Tumble Generator Valve (TGV) in Subaru vehicles (may require TGV delete)

Essential Tools and Parts

OBD-II scanner
Basic hand tools (such as wrenches, sockets, and screwdrivers)
Intake manifold gaskets
Intake manifold runner control valve
Actuator motor
Vacuum hoses

Step-by-step Procedure

Step 1: Use an OBD-II scanner to retrieve the P2006 code and any accompanying codes.

Step 2: Inspect the intake manifold, vacuum hoses, and related components for any visible signs of damage, leaks, or loose connections. Repair/replace any damaged components and ensure all connections are secure.

Step 3: Test the intake manifold runner control valve and actuator motor for proper operation and movement. Ensure they are not stuck or malfunctioning. Replace any faulty components.

Step 4: Check the electrical connections and wiring related to the intake manifold runner control system. Look for any open or shorted circuits. Repair/replace any damaged wiring or connectors.

Step 5: Clean or replace the intake manifold and valves to remove carbon buildup.

Step 6: Inspect and test the MAP sensor for proper functionality. Replace the sensor if it is faulty.

Step 7: Clear the codes using the OBD-II scanner and test drive the vehicle to verify if the P2006 code reappears. Monitor the system for any new issues or codes that may arise.

Notes and tips:

Refer to the vehicle’s service manual or manufacturer’s instructions for specific diagnostic and repair procedures.
Take precautions when working with the intake manifold to avoid damaging sensitive components.
Ensure all connections, hoses, and wiring are properly secured and in good condition.
Consider performing regular maintenance, such as cleaning the intake system, to prevent future carbon buildup.
