Ericsson graduated from GP2 to F1 in 2014, kick-starting his career as a Grand Prix driver with Caterham before joining Sauber the following year.
After three full years of racing at the pinnacle of motorsport, the Swede's best result to date is an 8th place finish achieved with the Swiss outfit in Australian in 2015.
Kaltenborn assessed her driver's potential and believes that on his merit Ericsson could achieve success given the proper equipment.
"You have to have that determination, have that opportunity and be at the right time at the right place and I don’t see why he can’t do that," she told Autosport.
"I’m very happy with his season. He has taken a very big step up, you see it in his whole appearance as well. He gives very valuable input to the team.
"He can definitely improve, there's a lot to do. He knows his strengths and he will learn more, and with his own experience he will find his own limits and how he can work on them."
The Swede spoke recently of his improved mental preparation and management which helped his progress in 2016 as he raced on a par with team mate Felipe Nasr.
"That's very important because it's not easy for young drivers out there when people have their prejudices with them for them to even handle certain situations,” Kaltenborn added.
"He's found his way and he's learned how to focus much more on things that are really important to him.
"In the last races he has really taken a step up which is to say that there is a lot of potential to come from him."
