Efficient engine air intake is important for the proper operation of your car’s engine. For this to happen, many engine components work together to ensure the proper delivery of air to the engine. On some vehicles, one of these components is the intake manifold runner position sensor. 

What happens when there is a fault in this sensor? Any fault in this sensor will most likely trigger the check engine light. P2015 is a trouble code related to how the intake manifold runner position sensor performs.

What Does the P2015 Code Mean? 

Diagnostic Trouble Code (DTC) P2015 stands for “Intake Manifold Runner Position Sensor /Switch Range/Performance (Bank 1).” This code simply indicates that the powertrain control module (PCM) has detected that the signal in the Bank 1 intake manifold runner position sensor is out of range. 

Bank 1 sits on the side of the engine where the #1 cylinder is located. Bank 2 refers to the side of the engine with the #2 cylinder. However, inline engines only have one bank. 

Some vehicle models are more prone to code P2015 than others. Have a technician check your vehicle immediately if you own a Volkswagen (especially VW GTI and Passat), or Audi and your diagnostics show P2015.

Note: The definition of OBD code P2015 may vary depending on the vehicle manufacturer. Consult your trusted repair manual or repair database for the exact code definition

Intake Manifold Runner Control System 

To understand the code more, let’s discuss the intake manifold runner control (IMRC) system. Your vehicle has an intake manifold that mounts to the engine. The role of runners or intake tubes inside the intake manifold is to deliver air to the engine. 

Many modern vehicles use an IMRC system to fine-tune the engine’s air intake. This system changes the length of the manifold runner by controlling the opening and closing of valves. Either a vacuum solenoid or an electronic actuator controls these valves.

The PCM determines IMRC operation with the help of the signal from the intake manifold runner position sensor. This sensor also helps determine if the IMRC valves are in the right position. Once the PCM detects that the signal is out of range, it will trigger the code. 

What are the Possible Causes of the P2015 Code? 

P2015 is a generic code supported by various makes and models. However, keep in mind that the causes of this code may vary depending on your vehicle’s make and model, as well as the condition of your vehicle. 

Here are some of the possible causes of the P0125 code: 

  • Malfunctioning Intake Manifold Position Sensor
  • Failing IMRC actuator/solenoid
  • Circuit issues, such as damaged wires or poor connections
  • PCM issues, such as outdated software

Circuit issues may contribute to the setting of the P2015 code.

What are the Common Symptoms of the P2015 Code? 

Symptoms of this code may present themselves differently depending on your car’s make and model. Here are common symptoms related to the code: 

  • Check Engine Light
  • Decreased Fuel Economy
  • Poor engine performance

How to Diagnose the P2015 Code 

Since there can be many possible causes of this code, diagnosing it can prove challenging. If you do not have DIY automotive repair skills, it is best to leave the job to an experienced professional. They would know how to properly identify the underlying issue that may cause the code. 

If you’re determined to diagnose this code yourself, you may consult your vehicle manufacturer’s repair information for the diagnostic steps and procedures. 

How to Fix the P2015 Code 

There is no fix that can work for all makes and models. For example, the repair steps for Audi OBD code P2015 may differ from the repair steps for other vehicles.

If you’re not well-versed with auto repair, it is best to leave the job to a professional. However, if you’re a skilled DIYer, you can refer to online auto repair manuals and guides to help you find the best repair procedures for your vehicle.
