Fault code P2015 is logged when the powertrain control module (PCM) has detected an issue with the intake manifold runner position sensor or switch in the first bank of the engine.
This happens when the signal being sent from the sensor to the PCM is out of the allowable range that the manufacturer of the vehicle presets.
The intake manifold runner allows a variable intake of air into the engine, rather than a fixed amount found with older engines. The intake manifold runner control valve is responsible for controlling this, while the position sensor monitors it.
The position sensor is responsible for relaying information about the position of the valve back to the PCM to allow for optimization and to ensure proper function. Malfunctions with the position sensor mean the PCM cannot properly determine how open or closed the intake is.
Bank 1 refers to the side of the engine where the first cylinder is located. This typically only applies to V-shape engines that have two banks.
Other Signs of This Problem
The symptoms of this problem can be difficult to detect. This means it is important to pay attention to the fault code logged.
The most obvious sign will typically be the presence of the Check Engine light on the dashboard.
In some cases, the vehicle will perform poorly as a result of incorrect air coming into the intake. This can result in symptoms like reduced acceleration and rough idling.
Additionally, there may be a slight reduction in fuel economy.
Because the signs of this problem can be hard to detect, it can be helpful to look out for additional fault codes. There may be other intake manifold fault codes logged. Look out for codes like P0075 to P0077 and P0081 to P0083.
What Could Be The Problem?
The cause of this issue will typically be found only in the intake manifold runner control valve circuit. This can include electrical issues or faulty parts.
One of the most common causes is a faulty intake manifold runner position sensor. It is possible for the intake manifold runner to be stuck in a position, causing this fault code to be logged.
Additionally, any electrical faults in this sensor’s circuit can cause this issue. These can include damaged wires and loose connections.
It is also possible that there can be electrical faults in the intake manifold runner control valve/solenoid circuit.
Fixes should be focused on the position sensor circuit itself as this is the most likely place the fault will be found.
A faulty intake manifold runner position sensor should be replaced.
Any electrical issues in the position sensor circuit need to be fixed. Additionally, electrical issues in the intake manifold control valve circuit must also be fixed.
A faulty intake manifold runner control valve needs to be replaced.
Fault code P2015 is considered a low issue in terms of seriousness. It does not have a major effect on the driveability or safety of the vehicle.
It is a good idea to have this issue resolved as soon as possible, up to a few weeks.
