### DTC P2008/58 Intake Manifold Runner Control Circuit / Open (Bank 1)

## for Preparation Click here

## DESCRIPTION

The swirl control valve is mounted on the intake manifold. The swirl control valve Vacuum Switching Valve (VSV) for changes the vacuum to actuate the actuator.
The ECM determines the opening angle of the swirl control valve, and uses the swirl control valve VSV to change the vacuum applied to the actuator's diaphragm to open and close the swirl control valve.

DTC No. | DTC Detection Condition | Trouble Area

P2008/58

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)

1. Swirl control valve VSV
2. Open or short in Swirl control valve VSV circuit
3. Intake manifold (swirl control valve)
4. EGR valve assembly
5. MAF meter
6. ECM

## INSPECTION PROCEDURE

HINT:

  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 running or stopped, if the engine was warmed up or not, and other data from the time the malfunction occurred.

NOTICE:

  If the ECM is replaced, the new ECM needs initialization (Click here).

1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P2008/58)

1. Connect the intelligent tester to the DLC3.

1. Turn the ignition switch ON and turn the intelligent tester ON.

1. Enter the following menus: Powertrain / Engine / DTC.

1. Read the DTCs.

   Result:

     Display (DTC Output) | Proceed to
     P2008/58 | A
     P2008/58 and other DTCs | B

| B |

SYSTEM OK

2.CHECK CONNECTION OF VACUUM HOSE

1. Check the vacuum hose connection of the swirl control valve system.

| NG |

REPAIR OR REPLACE VACUUM HOSE

OK |

3.INSPECT SWIRL CONTROL VALVE VACUUM SWITCHING VALVE (OPERATION)

| NG |

REPLACE SWIRL CONTROL VALVE VACUUM SWITCHING VALVE

OK |

4.INSPECT SWIRL CONTROL VALVE VACUUM SWITCHING VALVE (RESISTANCE)

1. Disconnect the S9 VSV connector.

1. Measure the resistance of the VSV.

   Standard resistance:

     Tester Connection | Condition | Specified Condition
     1 - 2 | 20°C (68°F) | 37 to 44 Ω

| NG |

REPLACE SWIRL CONTROL VALVE VACUUM SWITCHING VALVE

OK |

5.CHECK WIRE HARNESS (SWIRL CONTROL VALVE VACUUM SWITCHING VALVE - ECM)

1. Disconnect the S9 VSV connector.

1. Disconnect the E8 ECM connector.

1. Measure the resistance of the wire harness side connectors.

   Standard resistance:

     Tester Connection | Specified Condition
     S9-1 - E8-15 (SCV) | Below 1 Ω
     S9-1 or E8-15 (SCV) - Body ground | 10 kΩ or higher

| NG |

REPAIR OR REPLACE HARNESS AND CONNECTOR

OK |

6.CHECK WIRE HARNESS (MAIN RELAY)

1. Remove the integration relay from the engine room J/B (Click here).

1. Disconnect the 1J integration relay connector.

1. Disconnect the S9 VSV connector.

1. Measure the resistance of the wire harness side connectors.

   Standard resistance:

     Tester Connection | Specified Condition
     1J-5 - S9-2 | Below 1 Ω
     1J-5 or S9-2 - Body ground | 10 kΩ or higher

| NG |

REPAIR OR REPLACE HARNESS AND CONNECTOR

OK |

7.INSPECT INTAKE MANIFOLD (SWIRL CONTROL VALVE OPERATION)

| NG |

REPLACE INTAKE MANIFOLD

OK |

8.CHECK EGR VALVE ASSEMBLY

| NG |

REPLACE EGR VALVE ASSEMBLY

OK |

9.INSPECT INTAKE AIR TEMPERATURE SENSOR

1. Remove the MAF meter.

1. Measure the resistance of the IAT sensor.

   Standard resistance:

     Tester Connection | Condition | Specified Condition
     4 - 5 | -20°C (-4°F) | 13.6 to 18.4 kΩ
     4 - 5 | 20°C (68°F) | 2.21 to 2.69 kΩ
     4 - 5 | 60°C (140°F) | 0.49 to 0.67 kΩ

| NG |

REPLACE MASS AIR FLOW METER

OK |

10.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P2008/58)

1. Connect the intelligent tester to the DLC3.

1. Turn the ignition switch ON and turn the intelligent tester ON.

1. Enter the following menus: Powertrain / Engine / DTC.

1. Read the DTCs.

   Result:

     Display (DTC Output) | Proceed to
     P2008/58 | A
     No DTC | B
