P2005 trouble code definition
P2005 is a general OBD2 trouble code that indicates a malfunction with the intake manifold runner control circuit.
This code is similar to P2006, P2007, P2008, P2009, P2010, P2013 and P2015.
What the P2005 code means
The P2005 code means that the intake manifold runner is stuck open on bank 2. The ECU controls the manifold runner and when it is found to be stuck open the P2005 code is triggered. This causes the Check Engine Light to be displayed on the dashboard.
What causes the P2005 code?
- Stuck intake manifold runner
- Poor electrical connection
- Short or open wiring harness
- Faulty intake manifold runner control solenoid
What are the symptoms of the P2005 code?
The most common symptom is the Check Engine Light displayed in the dashboard.
The engine may also have a rough engine idle and a lack of power at lower speeds.
How does a mechanic diagnose the P2005 code?
A mechanic will begin by using a scan tool to check for any pending, stored, or history codes. Mechanics will note all the freeze frame data as well as any codes that were originally found and then the codes will all be cleared.
The mechanic will then test drive the vehicle in an attempt to duplicate symptoms.
Afterwards, they perform a visual inspection to look for any worn vacuum lines, broken or damaged wiring, and any other wear.
A the scan tool will be used to monitor the intake runner position and intake manifold runner control solenoid.
Lastly, a handheld vacuum pump will be used to test the intake runner.
Common mistakes when diagnosing the P2005 code
Commonly mistakes are made when steps are not followed in the order listed or are skipped. When this happens it is easy to miss basic faults in place of larger ones.
How serious is the P2005 code?
The P2005 code can indicate a serious fault if the intake runner fails. This can cause runner parts to be sucked into the engine causing extensive damage.
For normal vehicle operation the P2005 code should be repaired as soon as possible.
What repairs can fix the P2005 code?
- Intake manifold manifold runner replaced or repaired
- Repairing open or short in wiring harness
- Poor electrical connections fixed
- Replacement of intake manifold control solenoid
Additional comments for consideration regarding the P2005 code
An advanced scan tool is an important tool when diagnosing the P2005 code. It allows access to the live data stream which tells technicians sensor and solenoid operation and voltage.
In some circumstances the intake manifold runner flap can become stuck. A intake manifold cleaner can be used to dissolve the carbon deposits and free up the runner flap.
