P2007 Intake Manifold Runner Control Stuck Closed (Bank 2)
P2007 Intake Manifold Runner Control Stuck Closed (Bank 2) is a generic OBD-II diagnostic trouble code indicating that the Engine Control Module (ECM/PCM) has detected that the Intake Manifold Runner Control (IMRC) system on Bank 2 is stuck in the closed position or is not moving to the commanded position.
The Intake Manifold Runner Control system regulates the flow of intake air through the intake manifold. Depending on engine speed, load, throttle position, and other operating conditions, the ECM/PCM may command the runner flaps to open or close.
When the ECM/PCM commands the Bank 2 intake manifold runners to change position but detects that they remain closed, it can store P2007 and illuminate the Check Engine Light.
In simple terms, P2007 means the Bank 2 intake manifold runner system is not opening when the engine computer expects it to open.
This is important because P2007 does not necessarily mean that the electrical actuator itself has failed. The runners may be mechanically stuck because of carbon deposits, a damaged linkage, a seized shaft, a failed actuator, a vacuum problem, or another fault preventing the runners from reaching the commanded position.
The distinction between P2007 and the nearby IMRC codes is important:
-
P2007 = Bank 2 runner control stuck closed
-
P2008 = Bank 1 runner control circuit/open
-
P2009 = Bank 1 runner control circuit low
-
P2010 = Bank 1 runner control circuit high
-
P2011 = Bank 2 runner control circuit/open
-
P2012 = Bank 2 runner control circuit low
-
P2013 = Bank 2 runner control circuit high
Therefore, P2007 should primarily lead the diagnosis toward runner movement, actuator operation, linkage, vacuum supply, position feedback, and mechanical obstruction rather than assuming there is simply an open electrical circuit.
What Does P2007 Mean?
The code contains several important terms.
Intake Manifold Runner Control
Intake Manifold Runner Control, commonly abbreviated as IMRC, is a system that changes the effective intake-air path inside the manifold.
Many engines use runner flaps or valves to optimize airflow at different operating conditions.
Depending on the engine, the system may include:
-
Intake manifold runner flaps
-
Runner shafts
-
Mechanical linkage
-
Electric actuator
-
Vacuum actuator
-
Control solenoid
-
Position sensor
-
Position switch
-
Electrical wiring
-
ECM/PCM control
The exact design varies by manufacturer and engine.
Stuck Closed
The phrase “Stuck Closed” means the ECM/PCM believes the runner system has remained in the closed position when it should have moved.
For example, the ECM may command:
Closed → Open
but the position remains:
Closed → Closed
The computer can then determine that the runner system is not responding correctly.
A runner system can be stuck closed because of either an electrical/control problem or a mechanical problem.
Bank 2
Bank 2 refers to the cylinder bank that does not contain cylinder number one.
On a V-type engine:
-
Bank 1 = cylinder number one side
-
Bank 2 = opposite side
Therefore:
P2007 = Intake Manifold Runner Control Stuck Closed, Bank 2
The corresponding Bank 1 stuck-closed code is:
P2006 = Intake Manifold Runner Control Stuck Closed (Bank 1)
How Does the Intake Manifold Runner Control Work?
A simplified IMRC system works like this:
ECM/PCM → Actuator/Solenoid → Runner mechanism → Runner flaps
On systems equipped with a position sensor, the feedback path is:
Runner position → Position sensor → ECM/PCM
The ECM/PCM uses this information to determine whether the runners are actually moving as commanded.
At certain engine speeds and loads, closing or partially closing the runners can increase intake-air velocity.
At other operating conditions, opening the runners can provide a larger and less restrictive airflow path.
This allows the engine manufacturer to optimize the intake system for different operating conditions.
The exact opening and closing strategy is engine-specific.
Why Would the ECM Detect a Runner as Stuck Closed?
The ECM/PCM does not necessarily need to see a completely physically locked runner.
It may set P2007 when the actual runner position does not follow the commanded position.
For example:
Commanded position: Open
Actual position: Closed
If this mismatch persists long enough under the conditions required by the manufacturer's diagnostic strategy, P2007 may be stored.
This means that the fault can originate from several areas:
-
Mechanical runner mechanism
-
Actuator
-
Vacuum system
-
Control solenoid
-
Position sensor
-
Wiring
-
Electrical power supply
-
ECM/PCM control
Symptoms of P2007
The symptoms depend on how the runner system is designed and where the runners are stuck.
Check Engine Light
The Check Engine Light is the most common symptom.
The vehicle may continue to operate, especially if the ECM can compensate by using a default runner position.
Reduced Engine Performance
If the runners remain closed when they should open, intake airflow may become restricted.
Possible symptoms include:
-
Reduced engine power
-
Sluggish acceleration
-
Poor high-RPM performance
-
Reduced throttle response
-
Lack of power under heavy load
Poor High-RPM Performance
This is one of the more logical symptoms when the runners remain closed.
At higher engine speeds, the engine may require greater airflow.
If the runner passages remain restricted, the engine may struggle to breathe efficiently.
The driver may notice that the engine feels increasingly weak as RPM rises.
Poor Acceleration
The vehicle may accelerate more slowly than normal.
The problem can be especially noticeable during:
-
Hard acceleration
-
Highway acceleration
-
Passing
-
Uphill driving
-
High engine load
Engine Hesitation
Some vehicles may hesitate when the ECM expects the runner system to change position.
Rough Engine Operation
Depending on the engine design, an incorrect runner position may contribute to:
-
Rough running
-
Uneven power delivery
-
Unstable idle
-
Hesitation
However, rough idle is not guaranteed with P2007.
Reduced Fuel Economy
Incorrect intake-air management can reduce combustion efficiency and increase fuel consumption.
Increased Emissions
The wrong intake-air path can affect combustion characteristics and emissions.
Reduced Engine Response
The engine may feel less responsive when the throttle is opened.
No Noticeable Symptoms
P2007 can also occur with almost no noticeable driveability symptoms.
This can happen when:
-
The runners are only slightly restricted.
-
The ECM uses a default position.
-
The problem occurs only under specific conditions.
-
The engine has enough airflow to compensate.
In such cases, the Check Engine Light may be the only obvious indication.
Common Causes of P2007
Carbon or Sludge Buildup on the Runner Mechanism
Carbon buildup is an important potential cause.
Over time, deposits can accumulate around the intake manifold runner flaps and shafts.
This can make the mechanism:
-
Sticky
-
Difficult to move
-
Slow to respond
-
Completely stuck
The deposits may prevent the runners from opening even though the actuator itself is functioning.
Stuck or Seized Runner Flaps
The runner flaps may physically bind inside the intake manifold.
Possible causes include:
-
Carbon buildup
-
Dirt
-
Deposits
-
Corrosion
-
Damaged components
-
Worn shafts
-
Internal manifold damage
Broken Runner Linkage
Many systems use a mechanical linkage between the actuator and the runner flaps.
If the linkage breaks or becomes disconnected, the actuator may move while the runner flaps remain closed.
This can produce a situation where the electrical system appears to operate normally but the intake runners do not move.
Failed IMRC Actuator
An electric actuator can fail mechanically or electrically.
Possible actuator problems include:
-
Internal motor failure
-
Broken gears
-
Seized mechanism
-
Internal position-sensor failure
-
Electrical failure
-
Reduced actuator torque
Faulty IMRC Position Sensor
Some systems use a position sensor to tell the ECM/PCM where the runners are.
If the sensor provides incorrect feedback, the ECM may believe the runners are stuck closed even if they are physically moving.
Possible sensor problems include:
-
Incorrect signal
-
Dead spot
-
Intermittent signal
-
Internal electrical failure
-
Damaged wiring
Vacuum Leak
Vacuum-operated IMRC systems can develop problems when vacuum is insufficient.
Possible causes include:
-
Cracked vacuum hose
-
Disconnected vacuum hose
-
Leaking actuator diaphragm
-
Vacuum reservoir problem
-
Vacuum supply restriction
If the actuator cannot receive enough vacuum, the runners may remain closed.
Faulty IMRC Control Solenoid
Vacuum-operated systems often use an electrically controlled solenoid.
If the solenoid does not operate correctly, the actuator may not receive the required vacuum.
Damaged Wiring
Electrical wiring problems can prevent the actuator or solenoid from operating correctly.
Possible problems include:
-
Broken wires
-
Chafed insulation
-
Heat damage
-
Corrosion
-
Short circuits
-
Poor previous repairs
Loose or Corroded Connector
A poor electrical connection can cause intermittent or incomplete actuator operation.
Blown Fuse
If the IMRC actuator or control solenoid receives power through a fuse, a blown fuse can prevent operation.
The reason for the blown fuse should be identified before replacing it.
Low Battery or Charging Voltage
Some electronically controlled actuators may behave incorrectly when system voltage is abnormally low.
Check charging voltage if other electrical faults are present.
Intake Manifold Mechanical Damage
The internal runner mechanism may be physically damaged.
Possible problems include:
-
Broken flap
-
Damaged shaft
-
Broken mounting point
-
Worn linkage
-
Internal obstruction
Incorrect Installation
If the intake manifold or runner-control components were recently removed, incorrect installation can cause a stuck-closed condition.
Possible problems include:
-
Incorrect linkage installation
-
Disconnected connector
-
Incorrect hose routing
-
Misaligned actuator
-
Damaged runner mechanism
ECM/PCM Problem
An ECM/PCM problem is possible but relatively uncommon compared with mechanical or actuator-related faults.
The ECM/PCM should not be replaced before the external system has been tested.
Vehicles Commonly Affected by P2007

This is a general list rather than a list of vehicles guaranteed to set P2007.
The exact IMRC design depends on:
-
Model year
-
Engine
-
Intake manifold
-
Runner design
-
Actuator type
-
Position sensor
-
Vacuum system
-
ECM/PCM strategy
How Is P2007 Diagnosed?
P2007 should be diagnosed by determining why the Bank 2 runners remain closed when the ECM/PCM expects them to open.
A useful diagnostic sequence is:
Scan → inspect → command the actuator → observe runner movement → verify position feedback → test electrical/vacuum system → inspect mechanical mechanism → repair → verify
Step 1: Scan for Additional Trouble Codes
Use a diagnostic scan tool to check for:
-
Stored codes
-
Pending codes
-
History codes
-
Freeze-frame data
Look for related codes involving:
-
IMRC
-
Runner position
-
Runner control
-
Actuator
-
Position sensor
-
Vacuum control
-
Electrical circuit
-
Engine performance
-
Misfires
Additional codes can provide important clues.
For example, a runner-position sensor code stored together with P2007 may shift the diagnosis toward the feedback circuit.
Step 2: Check Freeze-Frame Data
Review the operating conditions when P2007 was recorded.
Depending on the vehicle, check:
-
Engine RPM
-
Engine load
-
Vehicle speed
-
Throttle position
-
Engine coolant temperature
-
Intake air temperature
-
Battery voltage
-
Commanded runner position
-
Actual runner position
This can help determine whether the problem occurs only under a particular operating condition.
Step 3: Inspect the Bank 2 Runner System
Locate the Bank 2 intake manifold runner mechanism.
Inspect for:
-
Broken linkage
-
Disconnected linkage
-
Loose components
-
Visible damage
-
Carbon buildup
-
Signs of binding
If the linkage is visibly disconnected, the actuator may be working while the runners remain closed.
Step 4: Check the Runner Mechanism by Hand
If the manufacturer's service procedure allows manual inspection, check whether the runner mechanism can move smoothly.
The mechanism should not be:
-
Seized
-
Excessively stiff
-
Binding
-
Grinding
-
Obstructed
If the runners cannot move freely, an electrical repair alone will not solve P2007.
Step 5: Command the IMRC Actuator
Use a capable scan tool to command the IMRC system where bidirectional control is supported.
Observe whether:
-
The actuator moves.
-
The linkage moves.
-
The runner flaps move.
-
The position sensor changes.
-
The commanded and actual positions agree.
This is one of the most useful tests because it separates several possible causes.
Step 6: Observe Commanded vs. Actual Position
Compare:
Commanded runner position
with:
Actual runner position
A typical fault pattern might be:
Commanded: Open
Actual: Closed
This strongly suggests that the system is not reaching the requested position.
The next step is to determine whether the problem is:
-
Actuator
-
Linkage
-
Vacuum
-
Position sensor
-
Wiring
-
Mechanical runner mechanism
Step 7: Inspect the Electrical Connector
Check the Bank 2 actuator, solenoid, and position-sensor connectors.
Look for:
-
Loose plugs
-
Bent terminals
-
Corrosion
-
Water intrusion
-
Backed-out pins
-
Damaged locks
-
Poor terminal tension
Step 8: Check Wiring
Inspect the harness for:
-
Broken conductors
-
Chafing
-
Melted insulation
-
Heat damage
-
Pinched wiring
-
Incorrect routing
-
Previous repair damage
Runner-control wiring can be exposed to significant engine heat and vibration.
Step 9: Verify Power and Ground
Depending on the system, verify:
-
Battery supply
-
Ignition supply
-
Fuse output
-
Ground
-
Actuator power
-
Solenoid power
Use the vehicle-specific wiring diagram.
Do not assume every IMRC system uses the same circuit configuration.
Step 10: Test the Actuator
If the system uses an electric actuator, test it according to manufacturer specifications.
Depending on the design, tests may include:
-
Power supply
-
Ground
-
Control signal
-
Motor operation
-
Current draw
-
Position feedback
-
Mechanical movement
An actuator that receives the correct electrical command but cannot move the runners may be defective.
Step 11: Test the Position Sensor
If the runner mechanism uses a position sensor, verify:
-
Reference voltage
-
Sensor ground
-
Signal voltage
-
Signal continuity
-
Signal change during runner movement
The signal should change appropriately as the runner position changes.
Step 12: Inspect the Vacuum System
For vacuum-operated IMRC systems, check:
-
Vacuum supply
-
Vacuum hoses
-
Control solenoid
-
Vacuum actuator
-
Diaphragm
-
Vacuum reservoir where applicable
A vacuum leak can prevent the runners from opening.
Step 13: Test the Control Solenoid
If a vacuum solenoid controls the runner actuator, verify:
-
Electrical power
-
Ground/control
-
Coil resistance
-
Activation
-
Vacuum flow
-
Vacuum retention
A faulty solenoid can prevent the actuator from receiving the necessary vacuum.
Step 14: Inspect for Carbon Buildup
If the actuator and control system operate correctly but the runners remain closed, inspect the internal runner mechanism for deposits.
Heavy deposits can cause the flaps or shaft to stick.
Step 15: Perform a Wiggle Test
While monitoring the runner position signal or actuator operation, carefully move the relevant wiring harness.
If the runner position suddenly changes or the signal drops out, investigate for:
-
Broken conductor
-
Loose terminal
-
Poor connector
-
Internal harness damage
Step 16: Compare Bank 1 and Bank 2
If the engine has equivalent runner-control systems on both banks, compare:
-
Actuator operation
-
Position sensor readings
-
Wiring
-
Power supply
-
Vacuum supply
-
Runner movement
Bank 1 can sometimes provide a useful reference when diagnosing Bank 2.
However, the two banks should only be compared when the manufacturer uses equivalent systems.
Step 17: Inspect the Intake Manifold Internally
If external components appear normal, the intake manifold may need to be inspected internally.
Look for:
-
Stuck runner flaps
-
Broken shafts
-
Carbon deposits
-
Damaged runner plates
-
Internal obstructions
-
Mechanical wear
Step 18: Check Manufacturer Technical Information
Before replacing major components, check for:
-
Technical Service Bulletins
-
Known runner failures
-
Actuator updates
-
Position sensor updates
-
Wiring issues
-
Connector problems
-
Software updates
-
Calibration procedures
Step 19: Perform Calibration or Relearn
Some vehicles require an IMRC calibration or relearn after replacing:
-
Intake manifold
-
Runner actuator
-
Position sensor
-
Runner assembly
Follow the manufacturer's procedure.
Step 20: Verify the Repair
After the repair:
-
Clear P2007.
-
Start the engine.
-
Monitor Bank 2 runner position data.
-
Command the runner system where supported.
-
Verify actuator movement.
-
Verify linkage movement.
-
Confirm runner movement.
-
Confirm position-sensor feedback.
-
Verify electrical or vacuum operation.
-
Perform any required calibration or relearn.
-
Complete the appropriate drive cycle.
-
Rescan the vehicle.
-
Confirm that P2007 does not return.
How to Fix P2007
The correct repair depends on the actual cause.
Clean the Runner Mechanism
If carbon buildup is preventing runner movement, the intake manifold and runner mechanism may require appropriate cleaning.
The cleaning procedure depends on the engine and manifold design.
Repair the Runner Linkage
If the linkage is disconnected or damaged:
-
Reconnect it if serviceable.
-
Replace damaged linkage.
-
Verify correct actuator-to-runner movement.
Replace the IMRC Actuator
If the actuator is confirmed defective, replace it.
After replacement, perform any required calibration or relearn.
Replace the Position Sensor
If the position sensor is defective and is serviceable separately, replace it.
Verify the sensor signal after installation.
Repair Vacuum Leaks
For vacuum-operated systems, repair:
-
Cracked hoses
-
Disconnected hoses
-
Vacuum leaks
-
Damaged actuator diaphragms
Replace the IMRC Control Solenoid
If testing confirms that the control solenoid is defective, replace it.
Repair Wiring or Connectors
Electrical repairs may include:
-
Repairing broken wires
-
Replacing damaged terminals
-
Repairing connectors
-
Correcting poor grounds
-
Repairing heat-damaged wiring
Replace the Intake Manifold
The intake manifold should not automatically be replaced because P2007 is stored.
Replacement may be necessary if:
-
Internal runner flaps are damaged.
-
Runner shafts are damaged.
-
The linkage cannot be repaired.
-
The actuator is integrated into the manifold and cannot be serviced separately.
-
The manufacturer specifies manifold replacement.
Update ECM/PCM Software
If manufacturer service information identifies a software issue, the ECM/PCM may require a calibration update.
Replace the ECM/PCM
ECM/PCM replacement should be considered only after the runner mechanism, actuator, sensor, wiring, vacuum system, and connectors have been thoroughly tested.

Can You Drive With P2007?
In many cases, a vehicle with P2007 can still be driven if the engine is running normally.
P2007 does not usually indicate an immediate catastrophic engine failure.
However, the underlying fault should be diagnosed because the intake runner system may be unable to provide the airflow characteristics intended by the manufacturer.
Driving with the problem may result in:
-
Reduced power
-
Poor acceleration
-
Reduced fuel economy
-
Increased emissions
-
Poor high-RPM performance
-
Additional engine-control faults
If the engine is severely misfiring, stalling, losing significant power, or the Check Engine Light is flashing, the vehicle should be inspected promptly.
Is P2007 a Serious Code?
P2007 is generally considered a low-to-moderate severity diagnostic trouble code, but the seriousness depends on the cause.
A runner flap that is slightly restricted may produce only a Check Engine Light.
A severely carbon-blocked runner mechanism, broken linkage, failed actuator, or damaged intake manifold can produce significant performance problems.
Ignoring the code for a long time may contribute to:
-
Reduced engine efficiency
-
Poor drivability
-
Increased emissions
-
Increased fuel consumption
-
Continued Check Engine Light
-
Additional intake-control problems
The actual cause should therefore be identified instead of simply clearing the code.
How to Prevent P2007
Not every IMRC failure can be prevented, but several maintenance practices can reduce the risk.
Recommended practices include:
-
Maintain the engine according to manufacturer recommendations.
-
Repair vacuum leaks promptly.
-
Inspect IMRC vacuum hoses where applicable.
-
Check electrical connectors during intake-system service.
-
Keep runner-control wiring away from excessive heat.
-
Address intake carbon buildup when appropriate.
-
Repair oil leaks that may contribute to intake deposits.
-
Address engine problems that increase intake contamination.
-
Do not ignore Check Engine Light warnings.
-
Inspect runner linkage during intake manifold service.
-
Use correct replacement components.
-
Perform required calibration after actuator or manifold replacement.
Final Thoughts
P2007 Intake Manifold Runner Control Stuck Closed (Bank 2) indicates that the ECM/PCM has detected that the Bank 2 intake manifold runner system remains closed or is not reaching the commanded open position.
The most important point is that P2007 does not automatically mean the intake manifold needs to be replaced.
The runners may be stuck because of:
-
Carbon buildup
-
Mechanical binding
-
Broken linkage
-
Seized runner shaft
-
Failed IMRC actuator
-
Faulty position sensor
-
Vacuum leak
-
Failed control solenoid
-
Wiring or connector problems
-
Intake manifold mechanical damage
Diagnosis should begin by scanning for additional trouble codes and reviewing freeze-frame data.
Next, inspect the Bank 2 runner mechanism, linkage, actuator, connectors, wiring, and vacuum system where applicable.
If the vehicle supports bidirectional scan-tool control, command the IMRC actuator and observe whether the actuator, linkage, and runner flaps actually move.
The commanded runner position should be compared with the actual position whenever reliable live data is available.
If the actuator moves but the runners remain closed, the problem is likely mechanical.
If the actuator does not move, check its power, ground, control signal, wiring, and vacuum supply before replacing it.
If the runners physically move but the ECM still reports them as closed, investigate the position sensor and its signal circuit.
The intake manifold should not automatically be replaced simply because P2007 is stored.
After the confirmed cause is repaired, clear the code, perform any required IMRC calibration or relearn, complete the appropriate drive cycle, and rescan the vehicle.
The final verification should confirm that the Bank 2 runners move to the commanded positions and that P2007 does not return.
