Saute the bacon, onion, celery, carrots and garlic in the olive oil in the Instant Pot on the sear setting until the bacon renders out.
Add all remaining ingredients except the andouille sausage and stir.
Place the lid on, lock and set the valve to closed.
Operate on Manual for 45 minutes.
When the time is up, use a wooden spoon to move the quick release valve open and let the steam subside completely.
While the steam is going down, saute the andouille sausage in a nonstick skillet until browned, then stir into the black eyed peas just before serving.
