P2013 Fault Code

Intake Manifold Runner Control Circuit High Bank 2a

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

The P2013 fault code indicates that there is an issue with the intake manifold runner control circuit for bank 2. This system is responsible for managing the airflow into the engine, optimizing performance by adjusting the length of the intake runners according to engine speed and load. When the circuit reports a high voltage condition, it can lead to poor engine performance, reduced fuel efficiency, and possible stalling issues.

What are the symptoms of the P2013 code?

Drivers may experience a variety of symptoms when the P2013 code is present, including:

• Lack of power during acceleration.
• Rough idling or stalling of the engine.
• Decreased fuel economy due to improper air-fuel mixture.
• Engine warning light (check engine light) illuminated on the dashboard.
• Unusual engine noises or vibrations.

What causes the P2013 code?

Several factors can contribute to the P2013 code being triggered:

• A defective intake manifold runner control (IMRC) actuator or solenoid.
• Wiring issues such as shorts or open circuits in the control system.
• Faulty Engine Control Module (ECM) detection or programming issues.
• Vacuum leaks affecting the operation of the intake manifold.
• Carbon buildup or mechanical failure in the intake manifold runner itself.

How to fix P2013?

To address the P2013 fault code, consider the following steps:

• Inspect the intake manifold runner control system for any visible signs of damage or wear.
• Test the IMRC actuator and related components for functionality, replacing them if necessary.
• Check wiring and connectors for any signs of corrosion or damage that could affect the circuit.
• Clean the intake manifold to remove any carbon buildup that may impede operation.
• If everything else checks out, reprogram or replace the ECM if it's determined to be faulty.
