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 (VSV) 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 VSV for swirl control valve to change the vacuum applied to the actuator's diaphragm to open and close the swirl control valve.
DTC Detection Drive Pattern | DTC Detection Condition | Trouble Area |
---|---|---|
After warming up engine, drive vehicle at an engine speed of 3200 rpm or higher with high load for 1 minute or more.* | When actual intake air volume detected by MAF 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) |
|
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/s. or more and MAP is 117 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 altitude, pressure drops by 1 kPa. Varies by weather.

INSPECTION PROCEDURE
Tech Tips
Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions 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 intelligent tester to the DLC3.
Turn the ignition switch ON and turn the tester ON.
Enter the following menus: Powertrain / Engine / DTC.
Read the DTCs.

Tech Tips
When MAP, MAF, Intake Air, and/or Intake Air Temp (Turbo)-related DTCs are stored along with P2006, perform troubleshooting for those DTCs first.

CHECK AIR INTAKE SYSTEM
Check for air leaks and blockages between the air cleaner case and turbocharger, and between the turbocharger and intake manifold.
Result | Proceed to |
---|---|
Leaks and/or blockages exist in the intake system | A |
No leaks or blockages in the intake system | B |
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.
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.

READ VALUE USING INTELLIGENT TESTER (MAF AND MAP)
Connect the intelligent tester to the DLC3.
Start the engine and turn the tester on.
Warm up the engine (engine coolant temperature is 70°C (158°F) or higher).
Enter the following menus: Powertrain / Engine and ECT / Data List / MAP and MAF.
Take a snapshot when the engine speed is maintained at 4000 rpm with no load.
Read the values of "MAP" and "MAF" in the Data List using the snapshot review function.
Result | Proceed to |
---|---|
MAF 84 gm/s. or more and MAP 117 kPa or more | C |
MAP less than 90 kPa | B |
Except above | A |
Tech Tips
The shift lever should be in neutral and the A/C switch and all accessory switches should be off.
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 altitude, pressure drops by 1 kPa. Varies by weather.
