In short, P2015 means a fault in the intake manifold runner position sensor/switch “A” circuit, part of the system that controls the intake runner valves. It can cause drivability problems such as rough idle, reduced power, and poor fuel economy, and the check engine light will typically come on. While not immediately life-threatening, ignoring it can lead to worse performance and emissions problems, so diagnosis and repair are advised.
What P2015 Means
The P2015 code identifies an issue with the intake manifold runner control (IMRC) system, specifically the position sensor or actuator circuit labeled “A.” In many engines, the IMRC system uses movable flaps or plates inside the intake manifold to optimize airflow at different speeds. A fault in the position sensor, the actuator/solenoid, or the wiring that connects them can cause the PCM to receive incorrect information about the runner position, triggering P2015.
How the IMRC system works
The IMRC system coordinates the opening and closing of the intake runners to improve efficiency and power. When the engine requires high RPM performance, the runners may open; at light load, they may close to improve torque and fuel economy. A faulty sensor or actuator disrupts this coordination, leading to a mismatch between what the engine perceives and what is actually happening inside the manifold.
Why the code matters for performance
If the IMRC cannot operate correctly, the engine may run with variable or limited airflow, causing power loss at certain RPM ranges, hesitation, or misfires. In some cases, fuel economy can suffer and the check engine light will stay on until the fault is repaired. Emissions performance may also be affected.
Symptoms
Before listing specific symptoms, drivers should note that P2015 can present as intermittent or persistent issues. Typical signs include:
- Rough or unstable idle
- Reduced power or hesitation during acceleration
- Decreased fuel economy
- Engine stalling or bucking at low speeds
- Illuminated Check Engine Light with code P2015
These symptoms vary by vehicle and by how the IMRC failure manifests (sticking open vs. sticking closed).
Possible Causes
Several issues can trigger P2015. The most common causes are:
- Faulty IMRC actuator or position sensor
- Vacuum leaks or carbon buildup around the IMRC components
- PPCM/ECM software calibration needing an update
- Intermittent electrical fault due to heat or vibration
Because the IMRC system is integrated with the intake and engine management, diagnosing the exact cause often requires a hands-on inspection and scanning with a capable OBD-II tool.
How It Is Diagnosed and Fixed
Repair decisions depend on the exact diagnosis, but typical procedures include:
- Confirm the code with a scan tool and note any related DTCs
- Inspect wiring and connectors to the IMRC actuator and position sensor for damage or corrosion
- Test the IMRC actuator/solenoid for proper operation, including voltage and ground checks
- Inspect the intake manifold and runner passages for carbon buildup or mechanical sticking; clean or service as needed
- Repair or replace the IMRC valve, sensor, or related wiring as required
- Update PCM software if the manufacturer recommends it, and perform a relearn or parameter reset if specified
- Road-test to verify the fault is resolved and that symptoms do not recur
Because IMRC components can be integrated with the intake manifold, some repairs may involve replacing the entire IMRC valve assembly or the manifold unit, which can affect cost and vehicle downtime.
Costs and Practical Considerations
Repair costs vary widely based on the vehicle, the exact failure mode, and labor rates. Typical ranges include:
- IMRC sensor or actuator replacement: part costs often $60–$400
- Labor: $150–$500 depending on accessibility and regional rates
- Possible manifold or valve assembly replacement: higher end of the range or more, depending on the model
Always obtain an itemized estimate and consider a second opinion if the suggested repair seems unusually expensive. In some cases, software updates can resolve a fault without replacing hardware, while in others, hardware replacement is unavoidable for a lasting fix.
Should You Drive It?
If the Check Engine Light is on and symptoms are noticeable, plan for service rather than prolonged driving. Moderate driving with mild symptoms may be possible in some cases, but continued operation could risk catalyst damage or further engine issues. A professional diagnosis is recommended to determine whether the vehicle should be driven to a shop or towed.
Summary
P2015 flags a fault in the intake manifold runner position sensor/switch “A” circuit, signaling a problem with the IMRC system. The consequence can range from minor drivability issues to significant power loss and higher emissions, depending on the vehicle and the exact failure mode. Diagnosis centers on the IMRC actuator, sensor, and wiring, with repairs potentially involving cleaning, sensor/actuator replacement, or, in some cases, replacement of the IMRC valve assembly or manifold. Costs vary widely, and timely service is advised to restore performance and maintain emissions compliance.
What can cause a P2015 code?
Usually, this happens because one of the intake manifold position sensors has failed, but it may also be due to a failed IMRC actuator or solenoid, a problem with the intake manifold as a whole, generalized wiring problems, including an open or short in the wiring harness, or, in rare cases, issues with the PCM.

Is it expensive to replace an IMRC sensor?
The cost to replace a faulty IMRC can vary widely depending on the vehicle make and model, ranging from approximately $100 to $300 or more. It can cause engine damage if left unaddressed, as it may lead to poor combustion and increased wear over time.

Can you still drive a car with a P2015 fault?
Can I Still Drive With The P2015 Error Code Present? In the case of the P2015 error code, the most notable symptom reported by vehicle drivers is an illuminated check engine light. This means driving with the P2015 fault code will be okay. However, your vehicle will expel increased vehicle emissions.
