Anderson reunited with the Jordan Grand Prix team in 2002. He co-designed the 2002 Jordan Honda EJ12 (with Eghbal Hamidy), which managed five points finishes, finishing the season 6th in the Constructors' Championship. Jordan lost backing of the Honda engines for 2003, and the Anderson-designed EJ13, now powered by Cosworth engines, finished the 2003 season 9th in the Constructors' Championship, but won a race (the 2003 Brazilian Grand Prix).
