P2005 OBD-II Trouble Code: Intake Manifold Runner Control Stuck Open Bank 2

P2005 trouble code definition

P2005 is a general OBD2 trouble code that indicates a malfunction with the intake manifold runner control circuit.

This code is similar to P2006, P2007, P2008, P2009, P2010, P2013 and P2015.

What the P2005 code means

What causes the P2005 code?

• Stuck intake manifold runner
• Poor electrical connection
• Short or open wiring harness
• Faulty intake manifold runner control solenoid

What are the symptoms of the P2005 code?

• The most common symptom is the Check Engine Light displayed in the dashboard.

• The engine may also have a rough engine idle and a lack of power at lower speeds.

How does a mechanic diagnose the P2005 code?

Additional comments for consideration regarding the P2005 code

An advanced scan tool is an important tool when diagnosing the P2005 code. It allows access to the live data stream which tells technicians sensor and solenoid operation and voltage.

In some circumstances the intake manifold runner flap can become stuck. A intake manifold cleaner can be used to dissolve the carbon deposits and free up the runner flap.
