He joined Ligier for 1988, ironically alongside the man he replaced at Ferrari, René Arnoux, but the team's first non-turbo powered car since , the Michel Beaujon-designed JS31 powered by a naturally aspirated Judd V8 engine, was totally uncompetitive, scoring no points and often failed to qualify, even against teams with much smaller budgets such as AGS and Rial (the French team's low point of the year was when both Johansson and Arnoux failed to qualify for the French Grand Prix at Paul Ricard in the first weekend of July). Unfortunately for Johansson, he failed to come to grips with the JS31, recording six non-qualifications during the season (compared to Arnoux who only failed to qualify twice). He did record the car's two best finishes of the year though, ninth placings in the opening race of the season in Brazil and the last race in Australia.
