  1. INSPECT EGR VALVE ASSEMBLY


    1. A01IQ4A

      Inspect the EGR valve assembly.


      1. When a vacuum of 27 kPa (200 mmHg, 7.88 in.Hg) is applied to the diaphragm chamber, check that the shaft rises and air flows out.

      2. Maintaining the above conditions, check that there are no leaks and the shaft stays in position.

      3. Check that the valve does not have heavy carbon deposits and is not stuck.

        If the result is not as specified, replace the EGR valve assembly.

    2. Inspect the EGR valve position sensor.

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 (VC) - 2 (E2) 20°C (68°F) 4.0 to 6.0 kΩ

        If the result is not as specified, replace the EGR valve assembly.

    3. Create a vacuum in the diaphragm chamber.

        (EGR valve is fully opened)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        3 (EGLS) - 2 (E2)

        20°C (68°F)

        EGR valve is fully opened

        		 3.9 kΩ

        20°C (68°F)

        EGR valve is fully closed

        		 1.0 kΩ

        Tech Tips

        The resistance increases in proportion to the opening angle of the EGR valve assembly.

        If the result is not as specified, replace the EGR valve assembly.
