1. INSPECT EGR VALVE ASSEMBLY


    A202938E01
  1. Measure the resistance according to the value(s) in the table below.
    Text in Illustration 
    *1
    Component without harness connected
    (Electric EGR Control Valve)

    Standard Resistance:
    Tester Condition
    Condition
    Specified Condition
    1 (M+) - 2 (M-)
    25°C (77°F)
    0.3 to 100 Ω

    HINT:
    The temperature indicated under "Condition" is the temperature of the electric EGR control valve assembly.

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



2. VISUAL CHECK EGR VALVE ASSEMBLY
  1. Visually check the electric EGR control valve for deposits.
    If there are deposits, clean the electric EGR control valve.

    NOTICE:
    When cleaning the electric EGR control valve, use a piece of cloth soaked with cleaning solvent. Spraying the solvent directly onto these parts or soaking the parts in the solvent may damage the parts.



    A202976E01
  1. Hold the electric EGR control valve up to a light, and then from the side indicated by the arrow in the illustration, visually check that there is no gap between the valve and body.

    OK:
    No light passes through (there is no gap between the valve and body).

    If light passes through (there is a gap between the valve and body), replace the electric EGR control valve assembly.

    HINT:
    Light passes through part A shown in the illustration even if the valve is completely closed; this is not a problem.
