• Solutions

The P2015 code refers to an issue with the Intake Manifold Runner Position Sensor or Switch for Bank 1. This component is crucial for controlling the airflow into the engine and optimizing performance across various RPM ranges. When this sensor fails or provides inaccurate readings, it can lead to suboptimal engine performance and fuel efficiency.

• The sensor monitors the position of the intake manifold runner, which adjusts to enhance airflow based on engine demands.
• An out-of-spec range signal from the sensor indicates performance issues.
• The code is specific to Bank 1, which is typically the side of the engine that contains cylinder number one.

What are the symptoms of the P2015 code?

When the P2015 code is triggered, you might experience the following symptoms:

• Reduced engine performance and acceleration.
• Increased fuel consumption due to inefficient airflow management.
• Engine stalling or hesitation during acceleration.
• Check Engine Light illuminated on the dashboard.
• Possible rough idling or unusual engine noises if the issue is severe.

What causes the P2015 code?

Several factors can contribute to the P2015 fault code:

• Faulty Intake Manifold Runner Position Sensor or circuit issues.
• A stuck or malfunctioning intake manifold runner.
• Electrical problems such as damaged wiring or poor connections.
• Carbon buildup in the intake manifold that affects the runner's movement.
• Issues with the Engine Control Module (ECM) that may misinterpret sensor signals.

How to fix P2015?

To resolve the P2015 code, follow these steps:

• Begin by inspecting the intake manifold runner position sensor and its electrical connections for damage or corrosion.
• Test the sensor with a multimeter to ensure it is functioning correctly.
• If the sensor is faulty, replace it with a new one.
• Clean the intake manifold to remove any carbon deposits that may hinder the runner's movement.
• Clear the fault code from the ECM and conduct a test drive to verify the repair.
