Hit SAUTE on the pressure cooker, and when it reads Hot, add the olive oil, chopped onions, garlic and kielbasa, and cook, stirring frequently, until sausage is lightly browned and onions are slightly soft
Hit CANCEL, deglaze pot with some of the broth, if necessary, and add the remaining ingredients to the pot. Pot will be full, but liquids should be below the fill line, so it's okay.
Place lid on pressure cooker, make sure vent is at Sealing position, and hit PRESSURE COOK for 4 minutes
Pot will take a few minutes to reach pressure (time will vary with different models) then begin counting down and start cooking
When pot beeps, allow a 5 minute natural release, then quick release remaining pressure
When pin drops, carefully remove lid, stir soup well, and serve
