Some vehicles have intake manifold runners that are typically partially closed during starting and idling conditions. They open to let in more air into the engine at higher revolutions per minute (RPMs). If your vehicle’s intake manifold runner is faulty then it can trigger diagnostic trouble codes (DTCs) like the P2005.
What Does the P2005 Code Mean?
Diagnostic trouble code P2005 stands for Manifold Runner Control Stuck Open Bank 2. This code triggers when the powertrain control module (PCM) can’t control the intake manifold runner as requested.
The intake manifold runner opens when the engine is at high RPM to let in more air so that the engine can have better performance and reduced emissions. Different vehicle manufacturers have different designs, but they all tend to use butterfly valves in the intake manifold.
Note: The definition of code P2005 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
What are the Common Causes of the P2005 Code?
The P2005 code can be triggered by the following:
- Failed intake manifold runner control actuator or solenoid
- Blocked vacuum lines
- Circuit issues, such as a damaged wire or poor connection
- Faulty PCM
What are the Common Symptoms of the P2005 Code?
Your vehicle might exhibit the following symptoms if the P2005 code is stored:
- Illuminated check engine light
- Poor engine performance
- Reduced fuel efficiency
How to Diagnose the P2005 Code
The P2005 is a generic powertrain code that can be stored in most modern vehicles. Remember that diagnosing this trouble code can vary depending on vehicle specifications.
If the P2005 code has been triggered, then you need to find the main problem causing the DTC before you make any repairs. The P2005 code might have a list of common causes, but you shouldn’t automatically assume that your vehicle has those issues because you might end up trying to repair a fully functional component.
Diagnosing this DTC might involve checking the intake manifold runner and its wiring. This task might require a lot of technical knowledge and specialized tools. If you think this is too daunting, then you should leave it to a professional mechanic.

How to Fix the P2005 Code
A proper diagnosis is the first step of any repair process. Accurately diagnosing the issue that’s triggering the code is important. Otherwise, you might be trying to fix a part that’s working properly.
There are many ways to fix the problems related to a specific OBD-II code because there are many possible causes. Once you’ve identified the issues causing the trouble code, then you can consult reliable online auto repair resources and how-to guides for possible fixes.
Since all vehicles are different, a fix for an OBD-II code for one vehicle might not work for another. Internal components can vary greatly among manufacturers. This is why you should consult a repair manual or repair database when it comes to troubleshooting and repairing DTCs. Chilton repair manuals can be useful. An ALLDATA DIY subscription might be better, as it provides detailed factory repair information for drivers who want to do the repairs themselves.
