Any fault in the intake manifold runner position sensor can trigger the check engine light. The P2015 code specifically points to a range or performance problem detected by the powertrain control module (PCM) in the Bank 1 intake manifold runner position sensor.
Diagnostic Trouble Code (DTC) P2015 stands for “Intake Manifold Runner Position Sensor/Switch Range/Performance (Bank 1).” It indicates that the PCM has received a signal from the Bank 1 intake manifold runner position sensor that falls outside the expected operating range.
Bank 1 refers to the side of the engine that contains cylinder #1. On inline engines, there is only one bank, so Bank 1 applies to the entire engine.
Note: The exact definition of P2015 can vary by vehicle manufacturer. Always consult a vehicle-specific repair manual or database for precise details.
The intake manifold mounts to the engine and contains runners that deliver air to each cylinder. Many modern engines use an intake manifold runner control (IMRC) system to optimize airflow under different driving conditions.
The IMRC system adjusts the effective length of the intake runners by opening or closing internal valves. These valves are typically controlled by a vacuum solenoid or an electronic actuator. The intake manifold runner position sensor reports valve position back to the PCM so the system can operate correctly.
When the PCM detects that this sensor’s signal is out of range, it sets the P2015 code.
Symptoms can vary by vehicle, but commonly include:
The P2015 code is generic, meaning it applies to many makes and models. However, the exact cause can differ depending on vehicle design and condition. Possible causes include:
While P2015 does not usually indicate an immediate safety risk, it can lead to reduced engine efficiency and drivability issues if ignored. Over time, unresolved IMRC problems may contribute to additional engine performance concerns.
Because multiple components can trigger this code, diagnosis can be challenging.
If you do not have DIY automotive repair experience, it is best to leave diagnosis to a qualified professional who has the proper tools and reference information.
There is no single fix that works for every vehicle. Repair steps depend on the root cause and vehicle design.
Always follow the repair procedures outlined in your vehicle’s service information.
Bank 1 refers to the side of the engine that contains cylinder #1. Inline engines only have one bank, so Bank 1 applies to the entire engine.
Yes, a fault in the intake manifold runner position sensor will most likely trigger the check engine light.
Yes, decreased fuel economy is one of the common symptoms associated with this code.
P2015 is a generic OBD-II code, but its exact definition and repair steps can vary by manufacturer.
Basic checks are possible, but accurate diagnosis often requires manufacturer-specific information and tools.
Yes, poor engine performance is a common symptom when the IMRC system is not operating correctly.
Yes, damaged wires or poor electrical connections can cause incorrect sensor signals that set the code.
PCM-related issues are possible but generally less common than sensor, actuator, or wiring problems.
If you lack automotive diagnostic experience or the code persists after basic checks, consulting a professional mechanic is recommended. Proper diagnosis ensures the correct repair and prevents unnecessary part replacement.
