P2005 Fault Code

Intake Manifold Runner Control Stuck Open Bank 2a

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2005 fault code indicates that the intake manifold runner control (IMRC) for Bank 2 is stuck in the open position. The IMRC is a system designed to optimize engine performance by adjusting airflow in the intake manifold. A malfunction in this system can lead to overall engine inefficiency and performance issues.

What are the symptoms of the P2005 code?

Drivers may notice a variety of symptoms when the P2005 code is triggered, such as:

• Decreased engine power and acceleration.
• Increased fuel consumption due to inefficient combustion.
• Engine misfires or rough idling.
• Possible illumination of the Check Engine Light (CEL).
• Performance issues at higher RPMs.

What causes the P2005 code?

Several factors could lead to the P2005 error code, including:

• A defective intake manifold runner control valve.
• Carbon buildup within the intake manifold.
• Issues with the vacuum lines connected to the IMRC.
• Faulty electrical connections or wiring harnesses.
• Problems with the Engine Control Module (ECM) not correctly interpreting input signals.

How to fix P2005?

To resolve the P2005 fault code, you can follow these steps:

• Inspect the intake manifold runner control valve for any damage or blockage.
• Clean any carbon deposits from the intake manifold, as this can hinder airflow.
• Examine the vacuum lines for leaks or disconnections and replace them as necessary.
• Check all electrical connections and wiring associated with the IMRC for faults or breaks.
• If needed, reprogram or replace the Engine Control Module.
