DESCRIPTION

The swirl control valve is installed to the intake manifold and composed of the swirl flap, swirl flap actuator and swirl flap position sensor.

The position sensor is supplied with a voltage of 5 V by the ECM. The signal of the position sensor is an analogue voltage signal.

The controllable swirl flaps are located in the swirl ports. Depending on the operating range, the swirl flaps are activated with different duty cycles. The further the swirl flaps are closed, the more fresh air is drawn in exclusively through the swirl port. This increases the swirl of the drawn-in fresh air.

In the bottom load and engine speed range the swirl flaps are closed variably according to the operating range.

When the engine speed is approximately 2250 rpm or higher and the fuel injection volume is approximately 30 mg/stk or higher, the swirl flap is fully open.

The position of the swirl flaps is also corrected depending on the ambient pressure. At ambient pressures less than approximately 880 hPa, the swirl flaps tend to be opened further.

Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are 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


  1. PERFORM ACTIVE TEST USING GTS (ACTUATOR TEST OF SWIRL FLAP)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Start the engine.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Actuator Test of Swirl Flap / Data List / Swirl Valve Actuator Position.


      Powertrain > Engine and ECT > Active Test
      Active Test Display
      Actuator Test of Swirl Flap
      Data List Display
      Swirl Valve Actuator Position
      OK
      The value of "Swirl Valve Actuator Position" changes according to the amount "Actuator Test of Swirl Flap" is operated, and the swirl flap operates smoothly.

  2. CHECK HARNESS AND CONNECTOR (SWIRL CONTROL VALVE - ECM)


    1. Disconnect the swirl control valve connector.

    2. Disconnect the ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      B129-3 (SCV+) - B112-49 (IA1+) Always Below 1 Ω
      B129-4 (SCV-) - B112-19 (IA1-) Always Below 1 Ω
