Common Questions
What does P2007 mean and how does it affect my car?
The P2007 code means that your vehicle's intake manifold runner control system is malfunctioning, which can lead to poor engine performance, reduced fuel efficiency, and increased emissions. If left unresolved, it can cause further damage to the engine and affect drivability.
What are the most common causes of P2007 and how much does it cost to fix?
Common causes of P2007 include a faulty intake manifold runner control valve, damaged wiring, or a vacuum leak. Repair costs can range from $150 to $400 for parts and labor, depending on the specific issue.
Can I drive my car with P2007 or should I stop immediately?
While it may be possible to drive your vehicle short distances with the P2007 code, it’s not advisable. Doing so can lead to decreased performance and may cause further damage. It's best to have the problem diagnosed and repaired as soon as possible.
How can I diagnose P2007 myself using GeekOBD APP?
You can use the GeekOBD APP to scan for the P2007 code and view freeze frame data to understand when the issue occurred. Check for any other related codes and inspect the intake manifold runner control system for visible issues like wear or damage.
What vehicles are most commonly affected by P2007?
The P2007 code is frequently seen in vehicles such as the 2007-2015 Honda Accord and the 2008-2013 Toyota Camry. It's essential to check for any recalls or Technical Service Bulletins (TSBs) related to the intake system in these models.
How can I prevent P2007 from happening again?
Regular maintenance, including cleaning the intake manifold and ensuring proper sealing, can help prevent future occurrences of the P2007 code. Additionally, using high-quality fuel and performing routine inspections can keep the intake system functioning optimally.
What is P2007?
The Diagnostic Trouble Code (DTC) P2007 indicates that the Engine Control Module (ECM) has detected a malfunction in the intake manifold runner control system. This system is designed to optimize airflow into the engine, enhancing performance and fuel efficiency. When the runner control is stuck open, it can lead to a mismanaged air-fuel mixture, which may cause poor engine performance, increased emissions, and potential long-term damage to the engine. Commonly seen in vehicles like the 2007-2015 Honda Accord and the 2008-2013 Toyota Camry, this issue can manifest as a check engine light on your dashboard. If ignored, you might experience symptoms like poor acceleration and reduced fuel efficiency. It’s crucial to address this issue promptly to avoid further complications, such as engine knocking or reduced power output. In addition, if your vehicle is equipped with an onboard diagnostics (OBD-II) system, the P2007 code will be stored, and you can access it using a diagnostic scan tool or an app like GeekOBD.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P2007 is present:
- Check engine light stays on constantly, indicating an ongoing issue with the intake manifold.
- Engine hesitates during acceleration, leading to a lack of power when you press the gas pedal.
- Fuel economy decreased by 10-15%, noticeable during daily driving and longer trips.
- Rough idling or stalling when the engine is warm, affecting smooth operation.
- Increased emissions, which may lead to failure during emissions testing.
Possible Causes
Most common causes of P2007 (ordered by frequency):
- The most common cause is a faulty intake manifold runner control valve, with a likelihood of around 60%. This valve can wear out or become stuck due to carbon buildup.
- Another frequent cause is a broken or damaged intake manifold runner control linkage, which may result in mechanical failure.
- Electrical issues such as damaged wiring or poor connections can also trigger the P2007 code, reducing the effectiveness of the system.
- Less common, but serious, is a vacuum leak in the intake system, which can lead to significant performance issues.
- A rare cause could be a malfunctioning ECM, which may misinterpret signals and trigger the P2007 code inaccurately.

Diagnostic Steps
Professional P2007 Diagnosis Process
Follow these systematic steps to accurately diagnose P2007. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion (5-10 minutes)
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes)
Step 3: Component testing - Use a multimeter or specific diagnostic tools to test the intake manifold runner control valve and associated components (20-30 minutes)
Step 4: System function test - Verify proper operation after repairs and clear codes using the GeekOBD APP (10-15 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm repair success and ensure the check engine light remains off (15-20 minutes)
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
