2KD-FTV EMISSION CONTROL SYSTEM ON-VEHICLE INSPECTION

Tech Tips

In a malfunction where the EGR system is always on, black smoke or white smoke may come out from the exhaust pipe. If this occurs, inspect the EGR system, as well.

Note

Always stop the engine when installing or removing the vacuum gauge, or removing the vacuum hose.


  1. INSPECT EGR OPERATION WHEN ENGINE IS COLD (Engine coolant temp. is 15 °C (59 °F) below)

    1. Using a 3 way connector, connect a vacuum gauge to the hose between the EGR valve and E-VRV.

    2. Start the engine.

    3. Check that the vacuum gauge indicates 0 at idle.

  2. INSPECT EGR OPERATION WHEN ENGINE IS HOT (Engine coolant temp. is 75 . 85 °C (109 . 194 °F))


    1. Using a 3 way connector, connect a vacuum gauge to the hose between the EGR valve and E-VRV.

    2. Warm up the engine.

    3. Check that the vacuum at idle.

      Standard
      30 kPa (225 mmHg, 8.9 in.Hg)

    4. Fully depress the accelerator pedal quickly.

    5. Check that the vacuum gauge indicator drops momentarily.

    6. Check that the vacuum gauge indicates 0 at 4000 rpm.

  3. INSPECT ELECTRIC EGR CONTROL VALVE ASSEMBLY

    1. Remove the EGR valve Click here.

    2. Apply a vacuum of 26.7 kPa (200 mmHg, 7.87 in.Hg) to the diaphragm chamber.

    3. Check that the EGR valve opens.
