      Target EGR Valve Pos
      Actual EGR Valve Pos

   5. Perform the following steps 1 to 4.

   6. Step 1

      1. Perform Actuator Test of EGR-Valve with control value of 0% (opening ratio in %).

      2. Monitor the difference of the control value and EGR valve Actuator Position value (0 +/- 3%). EGR valve must operate within 1 second.

   7. Step 2

      1. Wait for 2 seconds or more.

   8. Step 3

      1. Perform Actuator Test of EGR-Valve with control value of 94% (opening ratio in %).

      2. Monitor the difference of the control value and EGR valve Actuator Position value (0 +/- 3%). EGR valve must operate within 1 second.

   9. Step 4

      1. Wait for 2 seconds or more.

   10. Perform the above steps 1 to 4 and check that the part operates as specified.
