      Component without harness connected

      (Electric EGR Control Valve)

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

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

      Tech Tips

      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.

      Note

      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.

      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.

      Tech Tips

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