P2011 Fault Code

Intake Manifold Runner Control Circuit/Open Bank 2a

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

The P2011 fault code refers to an issue with the intake manifold runner control (IMRC) circuit associated with Bank 2. This system is responsible for optimizing airflow and engine performance by adjusting the position of the manifold runner. When the control circuit is open or malfunctioning, it can lead to reduced engine efficiency and performance problems.

What are the symptoms of the P2011 code?

Common symptoms associated with the P2011 fault code include:

• Reduced engine power and acceleration.
• Poor fuel economy.
• Engine stalling or misfiring.
• Check Engine Light (CEL) illuminated on the dashboard.
• Unusual noises coming from the intake area.

What causes the P2011 code?

Several factors can lead to the P2011 code being triggered, including:

• A faulty intake manifold runner control actuator or motor.
• Damaged wiring or connectors in the IMRC circuit.
• A malfunctioning engine control module (ECM).
• Intake manifold runner control vacuum leaks or blockages.

How to fix P2011?

To resolve the P2011 code, consider the following steps:

• Inspect the intake manifold runner control actuator for proper operation.
• Check wiring and connectors for any signs of damage, corrosion, or disconnection.
• Clear any vacuum leaks in the intake manifold system.
• If the actuator or motor is faulty, replace it with a new one.
• Reprogram or replace the ECM if it is determined to be defective.
