DTC Code | DTC Name |

P2006 | Intake Manifold Runner Control Stuck Closed (Bank 1) |
DESCRIPTION
The swirl control valve is mounted on the intake manifold. The vacuum switching valve is used to change the vacuum to control the swirl control valve.
The ECM determines the opening angle of the swirl control valve, and uses the vacuum switching valve (for swirl control valve) to change the vacuum applied to the actuator's diaphragm to open and close the swirl control valve.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory |
---|---|---|---|---|---|
P2006 | Intake Manifold Runner Control Stuck Closed (Bank 1) | When actual intake air volume detected by mass air flow meter continues to be smaller than volume estimated from boost pressure and intake air temperature sensor, ECM determines that swirl control valve is stuck closed (1 trip detection logic). |

CONFIRMATION DRIVING PATTERN
DTC Detection Drive Pattern | After warming up engine, drive vehicle at an engine speed of 3200 rpm or more with high load for 1 minute or more.* |
Tech Tips
*: When the above driving pattern cannot be performed due to road conditions, etc., the swirl control valve can be determined to be functioning normally if MAF is 84 gm/sec or more and MAP is 110 kPa or higher when the engine speed is at 4000 rpm with no load. However, no DTCs are stored when inspecting the vehicle with this method.
The above values were measured under standard atmospheric pressure. The values are influenced by elevation, weather conditions, etc.
Standard atmospheric pressure is 101 kPa. For every 100 m increase in elevation, pressure drops by 1 kPa. This varies by weather.

CAUTION / NOTICE / HINT
Tech Tips
Read freeze frame data using the GTS. Freeze frame data records the engine condition when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
PROCEDURE
CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P2006)
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the DTCs.

Tech Tips
When MAP, mass air flow, Intake Air, and/or Intake Air Temp (Turbo)-related DTCs are stored along with P2006, perform troubleshooting for those DTCs first.
MAP-related DTCs: P0105, P0107 and P0108.
MAF-related DTCs: P0100, P0102 and P0103.
Intake Air-related DTCs: P0110, P0112 and P0113.
Intake Air Temp (Turbo)-related DTCs: P0095, P0097 and P0098.

CHECK AIR INTAKE SYSTEM
Check for air leaks and blockages between the air cleaner case and turbocharger, and between the turbocharger and intake manifold.

Tech Tips
Inspect the air intake system, especially hoses and pipes between the air cleaner and turbocharger.
Check if the air cleaner element is significantly dirty.
Check for abnormal disconnections, pipe and hose squashing, and any damage in the intake system.
Using your hand, check whether the pipes and hoses in the intake system are securely connected.
The swirl control valve does not move due to deposits or the diaphragm not being air-tight, etc., and the specified output performance cannot be obtained.
If operating normally, when the engine is started, the swirl control valve quickly moves from fully open to fully closed.
By applying soapy water and revving up the engine, air leaks from the intake system can be checked by checking for bubbles.
Check for any modifications in the intake system made by the user.
