DTC Code P2015 – What does this code mean?

<ul> <li><a href="/problems/vw-check-engine-light-is-on"><b>Engine Light ON</b></a>: The check engine light or service engine soon warning light illuminates, indicating an issue with the intake manifold runner position sensor/switch circuit on bank 1.</li> <li><b>Reduced Engine Performance</b>: The vehicle may experience reduced engine performance, including a decrease in power and acceleration, due to improper intake manifold runner position.</li> <li><a href="/problems/vw-rough-idle"><b>Rough Idle</b></a>: The engine may idle roughly or inconsistently, as the intake manifold runner is not functioning correctly, affecting air flow.</li> <li><b>Poor Fuel Economy</b>: Fuel efficiency may decrease as the engine struggles to maintain optimal air-fuel mixture due to intake manifold runner issues.</li> </ul>

<ul><li>The intake manifold runner position sensor may be faulty, leading to incorrect readings and triggering the error code.</li><li>An open or shorted harness in the intake manifold runner position sensor can disrupt the signal, causing performance issues.</li><li>Poor electrical connections in the sensor circuit can result in intermittent or incorrect data transmission.</li><li>A malfunctioning intake manifold runner control solenoid valve can affect the movement of the intake manifold runners, impacting engine performance.</li><li>Mechanical defects within the intake manifold system can hinder the proper operation of the runners, leading to the error code.</li></ul>

<ul> <li><b>Initial Inspection</b>: Visually inspect the intake manifold runner control system for any obvious signs of damage or disconnection. Check the wiring harness and connectors for corrosion or damage.</li> <li><b>Check for Additional Codes</b>: Use a diagnostic scanner to check for any additional DTCs that may provide more context or indicate related issues.</li> <li><b>Test the Intake Manifold Runner Position Sensor</b>: Using a multimeter, measure the voltage and resistance of the intake manifold runner position sensor to ensure it is within the manufacturer's specifications.</li> <li><b>Inspect the Intake Manifold Runner</b>: Manually operate the intake manifold runner to ensure it moves freely without obstruction. Check for carbon buildup or mechanical binding.</li> <li><b>Examine the Control Module</b>: Inspect the Engine Control Module (ECM) for any signs of malfunction or failure. Ensure it is receiving and sending the correct signals to the intake manifold runner position sensor.</li> <li><b>Perform a System Test</b>: Conduct a system test using a diagnostic tool to verify the operation of the intake manifold runner control system and confirm the resolution of the issue.</li></ul>

<p>The DTC P2015 for Volkswagen indicates an issue with the <b>Intake Manifold Runner Position Sensor/Switch Circuit</b> on Bank 1. This can lead to <ul><li>reduced engine performance</li><li>increased emissions</li><li>potentially triggering limp mode</li></ul>. While not immediately critical, it should be addressed to prevent further engine inefficiencies and potential damage over time.</p>
