What Does P2015 Trouble Code Mean?
The P2015 trouble code indicates a problem with the intake manifold runner position sensor or switch circuit in bank 1.
This sensor monitors the position of the intake manifold runner flap, which controls the airflow into the engine.
When the Engine Control Unit (ECU) detects that the position of this flap is outside the expected range, it triggers the P2015 code.
This typically means the flap is stuck, not moving correctly, or there’s a circuit issue affecting the sensor’s performance.
The intake manifold runner flap optimizes airflow for different engine speeds and loads. At low RPMs, it stays closed to increase air velocity, improving low-end torque.
At higher RPMs, it opens to allow more air in, boosting power. If this system fails, it can disrupt your engine’s performance and efficiency.
A common cause is a faulty intake manifold runner position sensor. This sensor can wear out over time or get dirty, sending incorrect signals to the ECU.
Other causes include electrical issues like damaged wiring or connectors, and mechanical problems such as a stuck or broken flap.
Ignoring this code can lead to poor fuel economy, reduced power, and increased emissions. You might also notice the Check Engine Light on your dashboard, rough idling, or lack of acceleration.
Fixing the P2015 code involves diagnosing the exact cause. It could range from cleaning or replacing the sensor to repairing wiring issues or replacing the entire intake manifold assembly.
Identifying the root cause is crucial to avoid further damage and ensure your car runs smoothly.

How To Fix A P2015 Trouble Code
To fix a P2015 trouble code, follow these steps to diagnose and repair the issue:
1. Scan the Vehicle
Use an OBD-II scanner to confirm the P2015 code and check for any additional codes. This helps pinpoint the problem.
2. Inspect the Sensor and Wiring
Check the intake manifold runner position sensor and its wiring for damage, corrosion, or loose connections. Repair or replace any damaged components.
3. Clean the Sensor
Remove the sensor and clean it with an appropriate cleaner to remove any dirt or carbon buildup that might be causing incorrect readings.
4. Check the Intake Manifold Runner Flap
Manually inspect the flap for movement. Ensure it isn’t stuck or broken. If it’s not moving freely, clean or replace the flap.
5. Test the Voltage
Use a multimeter to test the voltage of the intake manifold runner position sensor circuit. Ensure it matches the manufacturer’s specifications. Replace the sensor if the readings are outside the normal range.
6. Check for Carbon Buildup
Inspect the intake manifold for carbon buildup. Clean it thoroughly if there is excessive carbon, as this can affect the flap’s movement.
7. Reset the Code
After making necessary repairs, use the OBD-II scanner to clear the trouble code. This will reset the Check Engine Light.
8. Test Drive the Vehicle
Take your car for a test drive to ensure the issue is resolved and the P2015 code doesn’t reappear.
Following these steps will help you diagnose and fix the P2015 trouble code, ensuring your vehicle runs smoothly again.
Conclusion
Now you know what the P2015 trouble code means and how to fix it.
