The P2008 code is a diagnostic trouble code (DTC) related to the Variable Intake Manifold (VIM) system, commonly found in many modern vehicles. When this code is triggered, it indicates a malfunction in the intake manifold runner control system, specifically related to the performance of the intake manifold’s runners. The runners play a critical role in optimizing engine performance by directing airflow to the engine's cylinders based on speed and load.
Understanding the P2008 code is essential for vehicle owners and automotive professionals alike. An issue with the intake manifold system can lead to reduced engine efficiency, increased emissions, and potential long-term damage to engine components.
Key Takeaways
- P2008 indicates a malfunction in the intake manifold runner control system.
- It can lead to poor engine performance and increased emissions.
- Immediate diagnosis and repair are crucial to avoid further complications.
- Understanding the common symptoms and causes helps in troubleshooting effectively.

Code Description and Meaning
The P2008 code is part of the On-Board Diagnostics II (OBD-II) system that vehicles use to monitor engine performance, emissions, and other critical aspects. When this code is stored in a vehicle’s computer, it means that the Engine Control Module (ECM) has detected an issue with the operation of the intake manifold runner control solenoid.
Important Notes:
- Intake manifold runner control (IMRC) systems adjust the length of the intake manifold depending on the engine speed.
- A properly functioning IMRC system enhances engine performance, fuel efficiency, and overall output.
- The P2008 code usually appears alongside other codes such as P2006 or P2007 due to accumulated issues within the intake system.
Common Causes
Understanding the common causes of the P2008 code can help prioritize repair efforts. Frequent reasons for triggering this code include:
- Faulty intake manifold runner control solenoid: The solenoid might fail, leading to improper operation of the runners.
- Clogged or damaged runners: Debris or carbon buildup can restrict airflow, affecting performance.
- Electrical issues: Wiring problems, such as shorts or breaks in the control circuit, can interfere with solenoid function.
- Vacuum leaks: Leaks in the intake system create imbalances that can trigger codes related to air-fuel ratios.
- Faulty ECM: In rare cases, the engine control module itself may malfunction, leading to erroneous readings.
Symptoms
When the P2008 code is present, the following symptoms commonly emerge:
- Check Engine Light: The most immediate sign is typically the illumination of the check engine light.
- Reduced Engine Power: Drivers may notice a decrease in acceleration and overall power due to compromised engine performance.
- Poor Fuel Economy: With the IMRC system malfunctioning, the vehicle may consume more fuel.
- Rough Idling: The engine may not idle smoothly, which can indicate airflow issues.
- Increased Emissions: A dysfunctional intake manifold system can lead to higher emissions levels, possibly failing emissions tests.
Diagnosis and Troubleshooting Steps
To effectively diagnose the P2008 code, follow these troubleshooting steps:
-
Scan the Vehicle: Use an OBD-II scanner to verify the presence of the P2008 code and check for any additional codes.
-
Inspect the Intake System:
- Look for visible damage or buildup within the intake manifold and runners.
- Check the solenoid for signs of wear or malfunction.
-
Examine Electrical Connections:
- Inspect wiring and connectors for signs of damage, corrosion, or loose connections.
- Use a multimeter to test the voltage and ground at the solenoid.
-
Perform a Vacuum Leak Test:
- Check for vacuum leaks using smoke testing or other methods.
-
Check the Functionality of the Solenoid:
- Apply direct voltage to the solenoid to see if it operates correctly.
-
Clear Codes and Test Drive:
- Clear the diagnostic codes and take the vehicle for a test drive to see if the issue reoccurs.
Repair and Replacement Procedures
Repair or replacement of components related to the P2008 code entails several steps. Here's a breakdown of the procedures:
Solenoid Replacement
-
Disconnect the Battery: Always disconnect the battery before working on electrical components to avoid shocks.
-
Locate the Solenoid: The intake manifold runner control solenoid is usually located near the intake manifold.
-
Remove the Old Solenoid:
- Disconnect the electrical connector from the solenoid.
- Remove any screws or bolts holding the solenoid in place and take it out.
-
Install the New Solenoid:
- Position the new solenoid in place, securing it with screws or bolts.
- Reconnect the electrical connector.
-
Reassemble and Test:
- Reconnect the battery, clear the codes, and perform a test run.
Cleaning or Replacing the Intake Manifold
- If debris is identified in the manifold, it may be necessary to remove and clean the intake manifold.
- Follow similar steps as above for disassembly; use professional cleaning agents to remove buildup.
- In severe cases, replace the intake manifold entirely.
Electrical Repairs
- If wiring issues are found, repair or replace damaged wires and connectors.
- Ensure all connections are secure and insulated to prevent future issues.
Cost to Fix
The cost to fix the P2008 code can vary significantly depending on the extent of the damage and the make and model of the vehicle. Here’s a general breakdown:
- Diagnostic Fees: $100 to $150 for an OBD-II diagnostic assessment.
- Solenoid Replacement: $100 to $300 including parts and labor.
- Intake Manifold Cleaning or Replacement:
- Cleaning costs range from $100 to $200.
- Replacement can escalate to $300 to $600 depending on labor and part costs.
- Electrical Repairs: These can vary widely but expect between $100 and $500 depending on the problem’s complexity.
Budget Summary Table
| Service | Average Cost |
