Adderly Fong will drive the Sauber in next week's one-day Pirelli Formula 1 tyre test, sharing duties with Marcus Ericsson.
The 25-year-old from Hong Kong had a relationship with Sauber last season, which included a Friday practice outing at the Abu Dhabi Grand Prix.
This year, he has been part of Lotus's roster of development drivers alongside a GP3 campaign, where he has yet to score a point.
Sauber said Fong's objective during the 12-hour test on Tuesday will be to qualify for the extension of his superlicence before handing the car over to Ericsson.
"I will do my best to give valuable feedback," said Fong. "I am looking forward to it, as well as the aim of extending my superlicence after completing 300km.
"Last year it was great to have the chance to drive the Sauber C33-Ferrari during FP1 here at the Abu Dhabi Grand Prix.
"Now I am curious about testing the current car."
Team boss Monisha Kaltenborn added: "We are pleased to have Adderly in the car again and to give him the opportunity to drive a current Formula 1 car.
"He immediately put in a solid performance in his last opportunities for us. We are confident Adderly will again put in every effort in this tyre test."
After missing the last round in Bahrain to contest the GT World Cup in Macau, Fong returns to GP3 for the finale in Abu Dhabi this weekend, switching from Koiranen GP to Carlin.
