It stays in the system until it is cleared.

As long as you haven't erased the codes they will be in the computer. Limp mode is usually caused by transmission control sensors. An OBD II code reader will not work to pull the codes. You need a mechanics $3000 scan tool.Source(s): Mitsubishi Master Tech
