Laymans terms

This code means that a part inside the engine that helps control air flow is stuck open on one side of the engine. It's like a door that should open and close but is stuck open.

Explanation

The intake manifold runner control system is responsible for adjusting the airflow into the engine's cylinders. If it's stuck open, it can affect how the engine runs.

Technical description

The P2005 code is triggered when the Engine Control Module (ECM) detects that the intake manifold runner control (IMRC) for bank 2 is stuck in the open position. This can lead to improper air-fuel mixture and affect engine performance.

Symptoms

• Check Engine Light is on

• Poor engine performance

• Reduced fuel efficiency

Common Causes

• Faulty intake manifold runner control valve

• Broken or disconnected vacuum lines

• Wiring issues or electrical faults in the IMRC circuit

Diagnosis steps

• Check for any stored trouble codes and freeze frame data

• Inspect the intake manifold runner control valve for damage or blockage

• Test the IMRC actuator and related wiring for proper operation

Repair procedures

• Replace the faulty intake manifold runner control valve

• Repair or replace damaged vacuum lines

• Fix any wiring or electrical issues in the IMRC circuit

Tools required
